14 CFR Parts 43, 91 and 145
[Docket No. FAA-2006-26408; Notice No. 12-03]
RIN 2120-AJ61
Repair Stations

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

This action would amend the regulations for repair stations by revising the system of ratings, the repair station certification requirements, and the regulations on repair stations providing maintenance for air carriers. This action is necessary because many portions of the existing repair station regulations do not reflect current repair station aircraft maintenance and business practices, or advances in aircraft technology. These changes would modernize the regulations to keep pace with current industry standards and practices.

We also discuss how you can get a copy of related rulemaking documents.

Authority for This Rulemaking

The FAA's authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency's authority.

This rulemaking is promulgated under the authority described in title 49, subtitle VII, part A, subpart III, section 44701, General requirements, and Section 44707, Examining and rating air agencies. Under section 44701, the FAA may prescribe regulations and standards in the interest of safety for inspecting, servicing, and overhauling aircraft, aircraft engines, propellers, and appliances. It may also prescribe equipment and facilities for, and the timing and manner of, inspecting, servicing, and overhauling these items. Under section 44707, the FAA may examine and rate repair stations.

This regulation is within the scope of section 44701 since it establishes new regulations for a repair station to have permanent housing for all its facilities, equipment, materials, and personnel. This regulation is within the scope of section 44707 since it revises the system of ratings for repair stations and specifies those instances when the FAA may deny the issuance of a repair station certificate, especially when a previously held certificate has been revoked.

I. Background

In 1989, the FAA held four public meetings to provide a forum for the public to comment on possible revisions to the rules governing repair stations. After considering the comments and data collected from these meetings, the FAA published a notice of proposed rulemaking in June 1999 (1999 NPRM).
1

The 1999 NPRM proposed significant changes to part 145 because the existing language was no longer appropriate and had become increasingly difficult to administer.

1
64 FR 33142; June 21, 1999.

In August 2001, the FAA published a final rule with request for comments and direct final rule with request for comments; final rule.
2

This final rule revised most of part 145 as proposed in the 1999 NPRM. However, it did not adopt the proposed revised repair station ratings and the quality assurance system due to the volume of negative comments received on the FAA's proposed changes to these areas.

2
66 FR 41088; August 6, 2001.

On October 19, 2001, the FAA tasked the Aviation Rulemaking Advisory Committee (ARAC) to address ratings and quality assurance for repair stations.
3

ARAC provided its recommendations in May 2002.
4

3
66 FR 53281; October 19, 2001.

4
A copy of the ARAC's recommendations can be found at
http://www.faa.gov/regulations_policies/rulemaking/committees/arac/.

On December 1, 2006, the FAA published the NPRM titled “Repair Stations” (2006 NPRM) that addressed ARAC's recommendations.
5

The original comment period was scheduled to close on March 1, 2007. However, the FAA received a request from the Aeronautical Repair Station Association to extend the comment period. In a notice published on February 27, 2007, the FAA granted a 45-day comment period extension to April 16, 2007.
6

The 2006 NPRM proposed the following changes to part 145:

5
71 FR 70254; December 1, 2006.

6
72 FR 8641; February 27, 2007.

• The system of ratings and classes would be revised significantly, including the creation of an avionics rating and the end of the issuance of

limited ratings (to be replaced by the issuance of limitations to the rating a repair station holds).

• Each repair station would set up and maintain a capability list of all articles for which it is rated. The list would identify each article by manufacturer and the type, make, model, category, or other nomenclature designated by the article's manufacturer. A repair station with an avionics or a component rating would also be required to organize its lists by category of the article.

• Each repair station would set up a quality system that includes an internal evaluation that reviews the complete repair station yearly.

• Applicants for a repair station certificate would include a letter of compliance as part of their application.

• Each repair station would be required to provide permanent housing for its facilities, equipment, materials, and personnel.

• Each repair station would be required to designate a chief inspector.

• The FAA would use certification from an authority “acceptable to the FAA” as a basis for issuing a certificate to a person located outside the United States.

• The FAA would identify reasons it could use to deny the issuance of a repair station certificate.

The FAA received more than 150 public comment submissions to the 2006 NPRM. While there was general support for revising the repair station rules, several commenters asked the FAA to withdraw the proposal. Many other commenters expressed concerns related to the proposed ratings system (particularly the proposed avionics rating), the capability list, quality system, letter of compliance, chief inspector, housing and facilities, and the FAA's denial of a repair station certificate.

On May 7, 2009, the FAA withdrew the 2006 NPRM because it did not adequately address the current repair station operating environment, which had changed significantly since the recommendations developed in 2001 by ARAC.
7

The FAA also noted that the withdrawal would give the FAA time to thoroughly review and properly address these substantial operating environment changes and the many issues raised by the commenters.

7
74 FR 21287, May 7, 2009.

The withdrawal notice stated that the FAA had started rulemaking to update and revise the regulations for repair stations to more fully address the significant changes in the repair station business model. This NPRM is the result of those efforts.

General Discussion of the Proposal

There are three major areas that this proposal will address:

• The system of ratings.

• The certification requirements.

• Repair stations providing maintenance for air carriers.

In addition, there are several other areas in part 145 that this NPRM will address. These are discussed in detail in an “Other Changes” section in the “Discussion of the Proposed Regulatory Requirements” portion of this preamble.

In the 2006 NPRM, the FAA proposed to require a formal quality system for all repair stations. While the FAA continues to believe that all repair stations should have a formal quality system to improve safety, the agency did not include such a requirement in this proposal. The FAA is in the process of introducing Safety Management Systems (SMS) rules, and it is anticipated that a future SMS rule will cover those repair stations operating under part 145. If the agency includes a quality system requirement in the final rule resulting from this proposal, a possibility exists that such systems would have to be modified once an SMS rule is formalized. The FAA does not believe this would be an efficient use of repair station resources based on the unknown differences that may arise.

Total Benefits and Costs of This Rule

The total costs of this proposal would be relatively small ($14.493 million over a 10-year period, spread amongst approximately 5,000 repair stations), but it is difficult to quantify the benefits. We believe, however, that the potential benefits, which derive in part from (1) Giving the FAA authority to (a) deny a repair station certificate to an applicant whose past performance resulted in a revocation, and (b) revoke all FAA-issued certificates of any person who makes fraudulent or intentionally false entries or records; (2) defining what operations specifications consist of and providing a well-defined process for both industry and the FAA to amend them; and (3) updating the ratings system, justify the costs of the proposed rule.

The current rule provides that, with certain unrelated restrictions, an applicant who meets the requirements of the rule is entitled to a repair station certificate regardless of a past regulatory non-compliance history. Because of at least one incident where the FAA revoked a repair station certificate for serious maintenance-related safety violations, and a key management official from that repair station shortly thereafter obtained a new repair station certificate under which improper maintenance resulted in a fatal accident, the National Transportation Safety Board (NTSB) recommended that a certificate applicant's past performance should be a consideration in determining whether a new certificate should be issued. That criteria currently applies to air carrier certificate applicants. The FAA agrees with the NTSB, and is proposing rules similar to those for air carriers in the hopes of preventing accidents like the one just described.

Although the current rule provides that no person may operate without, or in violation of, FAA-issued operations specifications, it does not define the term or explain what they consist of. Much confusion prevails within the repair station community and the FAA whether any or all of a repair station's operations specifications are considered part of its certificate and therefore entitled to NTSB review of any FAA-mandated changes to them. This proposed rule would make clear what operations specifications are and which ones are part of a repair station's certificate. It would also provide detailed processes for both FAA-initiated and repair station-initiated amendments to them. This would benefit both the repair station community and the FAA by providing a degree of certainty where currently there is only confusion.

In addition, the current ratings system dates to the 1930's and 1940's, and does not adequately address the way current aircraft are constructed. This hampers the FAA's ability to appropriately and consistently issue ratings, and it impedes repair stations' ability to accurately describe the work they perform. The repair station community and the FAA have struggled, and continue to struggle, with the application of current technology and business practices to an antiquated rule. The proposed rule would accommodate current advanced technologies and provide regulatory flexibility to accommodate future technological development.

1. System of Ratings

Part 145's system of ratings does not address current technology or industry practices. It is not dynamic and cannot adapt as new technologies are introduced. It is also not defined clearly and is open to inconsistent interpretation and application. These failings have resulted in repair stations having a variety of ratings to perform the same work. This system is confusing

to repair station operators and their customers, and presents increasingly difficult certificate management challenges to the FAA.

The rating changes proposed in the 2006 NPRM generated many comments. Most of those commenters were concerned that the proposed system of ratings would require a repair station to get FAA approval before changing or adding to the proposed required capability list. This proposal would not require a capability list, but would revise the capability list recording requirements for those repair stations who choose to use one. This is a potentially marked change for repair stations with class ratings that do not currently have a capability list of the items they maintain.

Under this proposal, the system of ratings would be reduced from eight ratings to five ratings. The ratings definitions would be revised to clearly indicate the type of work that a repair station is authorized to perform. A comparison of the proposed ratings with the current ratings follows:

2. Certification Requirements

The 2006 NPRM proposed that the FAA could deny an application for a repair station certificate if the applicant previously held a repair station certificate that had been revoked or if the applicant or certain key individuals who would exercise control over the new repair station had materially contributed to the circumstances that resulted in a prior repair station certificate revocation action. This proposal was similar to the authority contained in part 119 authorizing the FAA to deny applications for air carrier and commercial operator certificates. The commenters who opposed this proposal stated it was too open-ended and that it would be impossible to maintain a tracking list of disqualifying individuals.

While the FAA understands the commenters' concerns, the agency believes this requirement should be implemented. The FAA will add a question to the repair station application asking whether the applicant has a repair station certificate currently being revoked, or previously held a repair station certificate that was revoked as described in § 145.1051(e). The FAA notes that denial is not automatic. If the agency were to deny a certificate to an applicant under the proposed rule, the affected person could appeal that denial under the procedures provided in 14 CFR part 13.

The FAA is also proposing to clarify the certification requirements in § 145.51(b) on the equipment, personnel, technical data, and housing and facilities that must be in place for inspection at the time of certification or rating approval by the FAA. There has been much confusion about how a repair station can meet these requirements by contract. The FAA is proposing language to clarify that the contract applies only to ownership, and not to the demonstration phase of certification. If a repair station does not permanently possess these items, it must be able to demonstrate to the FAA that it has made arrangements with another person to provide such items whenever they are needed to perform work, and it must display these items and all associated lease agreements during certification.

3. Repair Stations Providing Maintenance for Air Carriers

In response to the 2006 NPRM, several repair stations that provide maintenance for air carriers raised concerns on the information that air carriers must provide. Currently, § 145.205 states a repair station working for an air carrier must follow the carrier's “program and applicable sections of its maintenance manual.” Repair stations that provide such work stated that the term “applicable sections” causes confusion because it is subjective and vague. They point out that air carriers, air operators, and even the FAA's own inspectors interpret this term differently.

In this NPRM, the FAA proposes language to clarify that when a repair station performs work as a maintenance provider to an air carrier, the repair station must perform that work in accordance with the maintenance instructions provided by the air carrier or air operator.

Line maintenance will be authorized as a limitation to an airframe rating. The regulations regarding line maintenance authorization will be deleted.

II. Discussion of the Proposed Regulatory Requirements

1. Transition

The FAA recognizes that the proposals in this NPRM represent a major revision to part 145. There would be many new and enhanced requirements as well as an in-depth change to the ratings system. These changes would require the revision of several existing repair station documents. These document changes would have to be reviewed and accepted by the FAA. This could then lead to delays in granting repair stations the approvals they need to operate.

To provide for the transition of current repair stations and at the same time accommodate the continued receipt of new applications, the FAA is proposing to retain the current regulations appended with the proposed regulations for 24 months. The current language would be retained with its current subpart lettering, A through E, and be revised only where necessary to accommodate the transition. The new rule would be located in new subparts, lettered F through J. Thus, the current Subpart B Certification § 145.51, Application for Certificate, would co-exist with a Subpart G Certification § 145.1051, Application for Certificate, during the 24-month transition period. The FAA anticipates that the final rule, if adopted, would become effective 60 days after publication.

Repair stations certificated before the effective date of the final rule would be able to continue to operate under the current regulations. They would have 24 months after the effective date of the final rule to show compliance with the proposed regulations by developing associated documents and submitting an FAA Form 8310-3, Application for Repair Station Certificate and/or Rating.

New applicants would be required to comply with subparts F through J upon the effective date of the final rule. Any repair station applying for a change to its repair station certificate requiring a new application, as provided for in the current rule, would be required to comply with subparts F through J as a condition of approval of the certificate change.

All repair stations certificated before the effective date of the final rule would have to timely apply for certification under the proposed rules if they intend to continue to operate without interruption. Repair stations are cautioned that waiting until later in the 24-month transition period may increase the risk that unforeseen circumstances might result in the repair station not having an active certificate until such time as the FAA can review the submitted documents and provide the repair station with a new repair station certificate.

All certificated repair stations would have to be in compliance with the provisions of subparts F through J no later than 24 months after the effective date of the rule. At that time, current subparts A through E would be removed and reserved. The rules would continue to carry the 1xxx (one thousand series) numbers to be consistent with any guidance or other documentation that is issued during the 24-month transition period.

To address the transition in the current regulations, the FAA proposes to revise subparts A through C as follows:

• Section 145.1(a) would state that subparts A through E will expire and be reserved 24 months after the effective date of the final rule.

• Section 145.1(b) would be changed to direct that subparts A through E apply to repair stations certificated before the effective date of the final rule until they are certificated under new subparts F through J or 24 months from the effective date of the rule.

• Section 145.1(c) would be revised to direct that a repair station certificated before the effective date of the rule would have to follow subparts A through E until it complies with subparts F through J.

• Section 145.51(a) would be changed to direct applications to be made in accordance with new § 145.1051.

• Section 145.53(a) would be revised to reflect that a certificate issued under subparts A through E would be valid for no longer than 24 months after the effective date of the final rule.

• Section 145.55(a) would be revised to state that a certificate issued to a repair station located outside the United States would not be valid 24 months after the effective date of the final rule.

• Section 145.55(b) would be revised to state that a certificate issued to a repair station located outside the United States may be renewed but not beyond 24 months from the effective date of the final rule.

• In § 145.55(c)(1), the reference to § 145.51 for the application procedures would be changed to § 145.1051.

• In § 145.57, the reference to § 145.51 for the procedures to be followed by a new owner would be changed to § 145.1051.

• In § 145.105(b), the reference to § 145.103 for change in housing would be changed to § 145.1103.

2. System of Ratings

The FAA proposes to revise the ratings and classes that may be issued to certificated repair stations. Under this proposal, the system of ratings would be reduced from eight ratings to five ratings. The ratings definitions would be revised to clearly indicate the type of work that a repair station is authorized to perform under each rating.

a. Airframe Rating (Current § 145.59(a)/Proposed § 145.1059(a))

Currently, the FAA may issue a repair station an Airframe rating with any of four class ratings: Classes 1, 2, 3, and 4. These classes are based on aircraft weight (large or small (as defined in 14 CFR 1.1)) and construction (composite or all-metal).

The use of construction as a basis for determining the class rating system no longer reflects the technology used in building today's aircraft. For example, at the time the Airframe rating was created, the aviation industry commonly referred to aircraft made from a combination of wood, fabric, and metal materials as aircraft with a “composite” construction. Today, the term “composite” construction refers to the use of carbon-carbon compounds and advanced polymers (which is fast becoming the standard in the industry). These types of materials were not even envisioned when the Airframe rating was created.

In addition, airframe manufacturers often use a mix of materials in current

aircraft construction. An all-composite or all-metal construction of an airframe is no longer the standard design. For example, an airframe could be metal while certain portions, such as control surfaces and fairings, are composite materials.

The continued use of weight as a basis for determining the class rating is also problematic. Historically, the FAA and the aviation industry used the weight classification of small and large aircraft to distinguish aircraft used in commercial air carrier service from those used in general aviation. Commercial operators typically used aircraft weighing over 12,500 pounds, while general aviation operators typically used smaller aircraft. This distinction also reflected the relative complexity of the aircraft. Today, however, aircraft weight reflects neither the complexity nor the intended use of an aircraft.

Therefore, it is clear that the Airframe rating needs to be updated. The FAA initially considered trying to define the term “composite.” This was difficult, at best. More importantly, any definition developed today may soon become outdated by further technological advances. The FAA has determined that a better approach is to have the underlying certification rules dictate the appropriate rating.

The FAA proposes to remove classes from the Airframe rating and group the aircraft that were previously covered by these classes in accordance with their certification standards under parts 23, 25, 27, and 29. All other aircraft not certificated under these parts would be in a separate category “all other aircraft.”

The FAA believes that grouping the Airframe rating into categories according to the airworthiness certification standards would better define the technology of the aircraft and relieve confusion. The proposed structure of the Airframe rating is:

• Category 1: All aircraft certificated under parts 23 and 27.

• Category 2: All aircraft certificated under parts 25 and 29.

• Category 3: All other aircraft.

The purpose of grouping airframes into categories 1 and 2 is to include aircraft that were originally certificated under their respective airworthiness standards. The third category would capture aircraft that were originally certificated under Civil Aeronautical Rules (CARs), Civil Aeronautical Bulletins (CABs) and/or Special Aeronautical Information Bulletins (SAIBs). This system of airframe rating categories would also capture future aircraft designs.

Category 3 would capture aircraft that are not included in categories 1 and 2. This would include aircraft such as unmanned aircraft systems, light sport aircraft, and manned balloons. This would also provide a category for other aircraft currently under design status and not yet certified under established certification regulations.

An application for the proposed Airframe rating would have to include a list of the make, model, or series of all aircraft that the repair station intends to maintain. This is a marked change for current airframe class rated repair stations.

The FAA also proposes to use the term “category” as a replacement for the term “class.” The term “class” has been used for so many years to mean a particular group of aircraft in part 145 that it seems impractical to try to apply it in a different context.

b. Powerplant Rating (Current § 145.59(b)/Proposed § 145.1059(b))

The current Powerplant rating has three classes: Class 1—Reciprocating engines of 400 horsepower or less, Class 2—Reciprocating engines of more than 400 horsepower, and Class 3—Turbine engines.

When the FAA established the current Powerplant rating, reciprocating radial engines that produced more than 400 horsepower powered nearly all large aircraft. These engines differed substantially from the horizontally-opposed reciprocating engines with less than 400 horsepower that manufacturers used to power general aviation aircraft. In 1941 (which was when the repair station ratings were originally developed), horsepower evaluations were the most common of the methods available to determine the complexity of engines.

Today, this methodology is antiquated and adds no value to the Powerplant rating. It is possible for small horizontally-opposed reciprocating engines to produce more than 400 horsepower. Further, most modern transport category aircraft now have turbine engines, while manufacturers no longer produce high horsepower radial engines. This is the exact opposite of what was in place when the FAA established the current Powerplant rating (i.e., manufacturers were just beginning to use turbine engines on civil aircraft). Therefore, separate classes for reciprocating engines are no longer useful.

Under the proposed Powerplant rating, the FAA intends to establish four categories:

• Category 1: Reciprocating engine.

• Category 2: Turbine engine.

• Category 3: Auxiliary Power Units (APU).

• Category 4: All other powerplants.

Reciprocating engines would be grouped into one category regardless of the horsepower generated. Turbine engines would continue to be grouped into one category. Since reciprocating and turbine engines do not cross technological boundaries, the FAA believes the two categories sufficiently capture the types of engine work that a repair station may perform.

A new category for APUs is proposed because they have evolved into a specialized technology in the powerplant arena. An APU refers to any gas turbine-powered unit delivering rotating shaft power or compressed air, or both, that is not intended for propelling aircraft. APUs often drive aircraft generators and air-conditioning packs. APUs also can be used as an extra source of energy to start the primary aircraft engines. The design configurations of some aircraft rely on an APU for provisional back-up electrical power in flight if the primary power sources fail.

The fourth category, All other powerplants, would be created to allow growth within the Powerplant rating for any other powerplant units not commonly used in aircraft today, such as solely electric engines.

Under the proposed rating system, a repair station holding a new Powerplant rating could perform maintenance, preventive maintenance, and alterations of the powerplant and associated articles that are necessary for the powerplant to operate properly.

An application for the proposed Powerplant rating would have to include a list of the make, model, or series of all aircraft engines and APUs that the repair station intends to maintain. This is a marked change for current powerplant class rated repair stations.

As was the case with the proposed Airframe rating, the FAA is proposing to use the term “category” as a replacement for the term “class.”

c. Propeller Rating (Current § 145.59(c)/Proposed § 145.1059(c))

Under the current regulations, the Propeller rating has two classes. Class 1 covers fixed-pitch and ground-adjustable propellers of wood, metal, or composite construction. All other propellers, by make, fall under Class 2.

This distinction is based on the different levels of complexity between a propeller with no moving parts and a propeller with a mechanical system that controls the pitch of the propeller while operating. Aircraft with small

reciprocating engines generally have fixed-pitch propellers, while aircraft with high horsepower engines have variable-pitch propellers. Although varying levels of complexity exist for propellers, most repair stations performing maintenance on propellers hold both class ratings.

As was the case with the current Airframe rating, the use of a propeller's composition as a basis to classify propellers has lost its usefulness.

The proposed Propeller rating would be structured to categorize propellers by complexity of designs and would no longer refer to the composition of a propeller as a method of categorization. The proposed structure of the Propeller rating is:

• Category 1: Fixed-pitch and ground-adjustable propellers.

• Category 2: Variable-pitch propellers.

• Category 3: All other propellers.

The proposed Propeller rating would permit a repair station to perform maintenance, preventive maintenance, and alterations on propellers and their respective individual component parts that are necessary for the propellers to operate. Examples of these propeller component parts would be propeller blade pitch controls, governors, pitch change assemblies, pitch locks, mechanical stops, and feathering system components. The proposed Propeller rating does not include main and auxiliary rotors (Airframe rating required) or rotating airfoils of aircraft engines (Powerplant rating required).

An application for the proposed Propeller rating would have to include a list of the make, model, or series of all propellers that the repair station intends to maintain.

As was the case with the proposed Airframe and Powerplant ratings, the FAA is proposing to use the term “category” as a replacement for the term “class.”

d. Component Rating (Proposed § 145.1059(d))

The current Radio rating (§ 145.59(d)) consists of three classes: Class 1—Communication equipment, Class 2—Navigation equipment, and Class 3—Radar equipment. In its report, ARAC indicated that technological advances in avionics have led to much controversy over this categorization of equipment. ARAC noted that modern avionics equipment typically integrates communication and navigation functions into a single avionics appliance. Radar and radio equipment that operate using pulse technology also serve communication and navigation functions. As such, repair stations performing work on avionics equipment often hold a Radio rating with all three of the classes.

The current Instrument rating (§ 145.59(e)) consists of four classes: Class 1—Mechanical, Class 2—Electrical, Class 3—Gyroscopic, and Class 4—Electronic. These classes were established based on the technology available at the time. However, most instruments currently operate using a combination of these technologies. These class distinctions are no longer appropriate.

The current Accessory rating (current § 145.59(f)) has three classes. Class 1 is mechanical accessories that depend on friction, hydraulics, mechanical linkage, or pneumatic pressure for operation. Class 2 is electrical accessories that depend on electrical energy for their operation and generators. Class 3 is electronic accessories that depend on the use of an electron tube, transistor, or similar device. Similar to the Instrument rating, the classes for the Accessory rating identify the article's principle of operation. Many articles maintained under this rating use a combination of principles, thus requiring repair stations to hold all the class ratings for an Accessory rating.

The classes defined in §§ 145.59(d), (e), and (f) are essentially the same as when they were implemented in 1941. The technological advances in radios, instruments, and accessories have often combined many of the functions and modernized the construction of the articles detailed in these classes. Under oo current rule, repair stations may not be able to categorize properly the articles on which they desire to perform maintenance. Therefore, repair stations may be required to possess tools and equipment that are either antiquated or not available.

The FAA is proposing a new Component rating to replace the Radio, Instrument, and Accessory ratings. The proposed Component rating would allow repair stations to perform maintenance, preventive maintenance, and alterations on various components and related articles that are not installed on an airframe, powerplant, or propeller. The various components and articles that are currently included in a Radio, Instrument, or Accessory class rating would be absorbed into the Component rating. A repair station with a Component rating would be required to have an Airframe, Powerplant, or Propeller rating with limitations to install components or appliances. The FAA believes that the comments generated in previous rulemaking attempts are being addressed by this proposed rating. The Component rating would open opportunities for repair stations to have numerous components listed on their operations specifications, thus generating more work and revenue.

An application for the proposed Component rating would have to include a list of the components that the repair station intends to maintain.

e. Specialized Service Rating (Proposed § 145.1059(e))

The FAA is proposing a new rating, called Specialized Service, to address what is currently listed as specialized services functions of a limited rating. This rating would be different from the other ratings in that it focuses on the maintenance being performed rather than the article being maintained. A repair station with a Specialized Service rating could perform a specialized maintenance function that might apply across multiple other ratings.

The proposed Specialized Service rating is substantially the same as the existing limited rating for specialized services in § 145.61. The Specialized Service rating would allow a repair station to perform a specific and unique function associated with the maintenance, preventive maintenance, or alteration of an article. The repair station's operations specifications would list the Specialized Service rating and the specification used in performing that specialized service. The specification could be a military, industry, or applicant-developed specification that was approved by the FAA. Examples of specialized services would include, but not be limited to, non-destructive testing or inspection, welding, heat-treating, plating, and plasma spraying.

If specialized service functions are contained within a repair station's existing ratings, the repair station would not require an additional rating to perform that service. For example, if an Airframe rated repair station has the in-house capability to perform x-ray inspections in accordance with the airframe Instructions for Continued Airworthiness, it would not need to have a Specialized Service rating to perform that function on an airframe for which it is already rated.

As is the case with the current limited specialized service rating, this rating could enhance the capabilities of some repair stations that are limited by the article-based rating they possess. This individual rating would allow a repair station to perform the maintenance function outside of its article-based rating—to specialize in a particular maintenance function without being required to hold an Airframe,

Powerplant, Propeller, or Component rating to perform the service.

An application for the proposed Specialized Service rating would have to include a list of the services, with associated specifications, that the repair station intends to provide.

f. Limitations to Ratings (Current § 145.61/Proposed § 145.1061)

Section 145.61 provides for limited ratings based on a repair station performing maintenance, preventive maintenance, or alterations on a particular make or model of aircraft, powerplant, propeller, radio, instrument, accessory, or part thereof, and for performing specialized maintenance.

The FAA is proposing that limited ratings no longer be issued. Proposed § 145.1061 would more accurately detail the FAA's current practice of issuing limitations to the rating of a certificated repair station. For example, if a repair station intends to perform only interior configuration work or aircraft painting, the FAA would issue the repair station a limitation to its Airframe rating and list that limitation on the repair station's operations specifications. The repair station's operations specifications would specify the rating to which the limitation applies in sufficient detail to describe the maintenance capabilities of the repair station.

The FAA believes that the ability to place limitations when necessary on a repair station's rating is essential to accurately reflect the repair station's capabilities. Currently, a repair station's operations specifications contain provisions for this purpose. This proposed change would add regulatory language to control what has historically been an essential part of the rating system.

3. Certification Requirements

Several areas within subpart B (Certification) of part 145 have, over time, caused confusion in the industry and within the FAA. Changes within this subpart are needed to clarify existing regulatory language and, in some cases, create regulatory language where essential practices have long been imposed through FAA guidance. Changes are also needed in this subpart to align language with other proposed section changes contained in this NPRM. In addition, this NPRM contains a proposal to allow for certification denial when certain enforcement history exists.

a. Application for Certificate—Items Required (Current § 145.51(a)/Proposed § 145.1051(a))

Current § 145.51(a) details, and § 145.1051(a) proposes to detail, those items that must be included in an application for a repair station certificate and rating.

The FAA proposes to add a provision that would require an initial applicant for a repair station certificate to provide the FAA with a letter outlining how the applicant will comply with each section of part 145 (see proposed § 145.1051(a)). The FAA refers to this as a “letter of compliance.” Under longstanding FAA policy and practice, applicants have provided this letter in the past. Since this letter has long been an essential part of the application process, the FAA believes it appropriate to propose a regulatory basis for it. Also, because applicants have been providing these letters by policy, the FAA believes no additional cost would be incurred.

Current § 145.51(a)(1) requires that an application for a repair station certificate include a repair station manual acceptable to the FAA as required by current § 145.207, and § 145.51(a)(2) requires that the application include a quality control manual acceptable to the FAA as required by current § 145.211(c). These requirements are found in proposed §§ 145.1051(a)(2) and (a)(3), respectively. The FAA is also proposing in § 145.1051(a)(3) that the repair station manual and the quality control manual may be contained in the same document if they are clearly identified.

Currently, an applicant is required to provide a list by type, make, or model of each article for which the application is made (§ 145.51(a)(3)). This requirement is not explicitly linked to the rating system found in § 145.59. The FAA proposes to revise this requirement (in proposed § 145.1051(a)(4)) to specifically reference the rating system (as found in proposed § 145.1059). This would help the applicant better understand the certification requirements and align the information provided at the time of application with the actual ratings allowed through the regulation. The FAA does not anticipate that this change would burden current repair stations, and it would ensure that applicants submit the necessary information without adding new requirements.

As repair stations have become larger and more complex, it is apparent that identification of the principal repair station location has often become difficult to ascertain for the public as well as for the FAA. This has made it difficult for the FAA to fulfill its obligation to provide appropriate oversight. Current § 145.51(a)(5) requires an applicant to provide a description of its housing and facilities, in accordance with § 145.103. The FAA is proposing clarifying language in § 145.1051(a)(6) that would require the applicant to identify all facilities that will make up the repair station at the time of application.

The FAA is not proposing changes to the requirements in current §§ 145.51(a)(4), (6) and (7). However, in proposed subpart G, these requirements would be found in proposed as §§ 145.1051(a)(5), (7) and (8) respectively.

b. Application for Certificate—Appropriate Equipment (Current § 145.51(b)/Proposed § 145.1051(b))

Current § 145.51(b) requires that the equipment, personnel, technical data, and housing and facilities required for the certificate and rating, or for an additional rating, must be in place for inspection at the time of certification or rating approval by the FAA. This section also states that an applicant may meet the equipment requirement if it has a contract acceptable to the FAA with another person to make the equipment available to the applicant at the time of certification and at any time it is necessary when the relevant work is being performed by the repair station.

This provision was included for the first time in the 2001 final rule in response to comments received on the 1999 NPRM. The commenters expressed concerns that the requirement to have all the equipment in place at the time of certification would be unnecessarily burdensome. Others noted that it is important only that the equipment be in place when it is needed to perform the work. Similarly, commenters opposed the requirement in then proposed § 145.111 (Equipment and material requirements) that would have required repair stations to have, located on the premises and under their full control, the equipment and material necessary to perform the maintenance appropriate to their ratings. They said the requirement would preclude repair stations from renting or leasing equipment. The commenters also noted that a renting or leasing option would be particularly important for expensive, rarely used tools.

In response to those comments, the FAA revised the text in § 145.51(b) to permit an applicant for a repair station certificate to meet the equipment requirement by having a contract acceptable to the FAA that would ensure the equipment would be

available when the relevant work is performed. Agreeing with the commenters' concerns over the burden of having to purchase expensive, rarely used tools to have in place during initial certification, the FAA stated that its new contract provision “will accommodate those repair stations that do not plan to purchase expensive equipment that may not be used regularly” (66 FR 41095, August 6, 2001). The preamble discussion, however, noted that the provision did not relieve an applicant from having the equipment in place and available for inspection at the time of certification. While recognizing that, under this provision, an applicant need not physically retain the equipment after certification, the FAA found it necessary that each applicant have the equipment in place during the certification process. During the certification inspection, the FAA could “observe the placement of the equipment, whether the equipment works, and whether the applicant can use the equipment properly.”
Id.

Similarly, in response to the comments on proposed § 145.111, the FAA revised the text (now found in § 145.109) to provide that: “The equipment, tools, and material must be located on the premises and under the repair station's control when the work is being done.” This change also accommodated the commenters' concerns about not having to purchase expensive, seldom used equipment to have permanently in place when they could instead obtain it through contract when needed.

These issues were discussed in the 2006 NPRM, when the FAA addressed and attempted to clarify what it termed was an ambiguity in the existing text. The preamble stated that this “ambiguity results from the phrase specifying that the equipment requirement could be met `if the applicant has a contract acceptable to the FAA with another person
to make the equipment available
to the applicant at the time of certification' ” (71 FR 70256, Dec. 1, 2006 (emphasis in original)).

The FAA noted the possibility of inconsistent application of this provision by different FAA inspectors. For example, one inspector might require all of the equipment to be placed on site for initial inspection, and another might only review the contract. Noting that the safety basis for the equipment requirement is that the equipment be in place when the work is being performed, the FAA proposed revised text in the 2006 NPRM to clarify that the requirement for initial certification could be met by a contract to make the equipment, tools, and test apparatus available to the repair station at any time it is necessary when the relevant work is being performed.

The FAA has reconsidered this issue and has determined that the “clarification” proposed in the 2006 NPRM was not entirely consistent with the underlying purpose of the provision published in the 2001 final rule. As noted above, the 2001 preamble supported the change to allow contracting for equipment availability by noting that it would “accommodate those repair stations that do not plan to purchase expensive equipment that may not be used regularly.” The preamble also made clear that the new provision did
not
relieve an applicant from having the equipment in place and available for inspection at the time of certification. Thus, the clarification offered in the 2006 NPRM was not in full accord with the agency's intent set forth in the 2001 preamble, which would have required applicants to have basic equipment in place for inspection.

The FAA believes it should not grant a repair station certificate to an applicant with a virtually empty building based merely on a showing it can get the required equipment by contract when needed. Therefore, the FAA proposes to change the rule to remove any ambiguity by requiring the repair station to meet the equipment requirements of proposed § 145.1051 by having the equipment available for inspection at certification. The repair station would not need to own the equipment but would be required to present the equipment during certification and have it available thereafter.

The FAA also proposes to clarify the scope of the kinds of items a repair station must have for initially obtaining certification by adding both tools and test apparatus to the list of items a repair station must have on site. While the term “equipment” could be interpreted to include many examples of each, adding the term “tools” to the regulation would ensure that an applicant for a repair station certificate also have on site certain tools necessary for the rating sought that individual mechanics or repairmen might not possess. This might include tools that are of a specialized nature for the rating or other tools that might be too large or expensive, or of a limited specialized nature. For the same reasons, and for consistency with the requirements of § 43.13(a), the FAA proposes to add “test apparatus” to the list of items a repair station must have in place for inspection at the time of initial certification or rating approval.

c. Application for Certificate—Repair Stations Outside the United States (Current § 145.51(c)/Proposed § 145.1051(c))

Current § 145.51(c) requires an applicant for a certificate for a repair station located outside the United States to show the certificate and/or rating is necessary for maintaining or altering certain aircraft and articles. The result of this language unintentionally requires the repair station applicant to maintain both aircraft and articles. The FAA proposes to change the word “and” to the less restrictive “or” in proposed § 145.1051(c).

d. Application for Certificate—Denial (Proposed § 145.1051(e))

The 2006 NPRM proposed that the FAA could deny an application for a repair station certificate if the applicant previously held a repair station certificate that had been revoked or if the applicant or certain key individuals who would exercise control over the new repair station had materially contributed to the circumstances that resulted in a prior repair station certificate revocation action. This is similar to the current authority contained in part 119 authorizing the FAA to deny applications for air carrier and commercial operator certificates. The commenters who opposed this proposal stated it was too open-ended and that it would be impossible to maintain a tracking list of disqualifying individuals.

At the present time, the FAA is not planning to maintain a tracking list of individuals who might be disqualified under this section. The agency is, however, planning to add a question to the repair station application inquiring into the disqualifying criteria set forth in this section,
e.g.,
whether the applicant held a repair station certificate that had been revoked or that is in the process of being revoked. A truthful answer here would be imperative in view of proposed § 145.1012, because an intentionally false answer to the question could result in the suspension or revocation of any FAA-issued certificate held by that applicant.

While the FAA understands the concerns of the commenters, the agency believes this requirement should be implemented to address safety concerns. For example, a chief inspector from a repair station that lost its certificate for serious maintenance-related safety violations applied for and received a new repair station certificate. That individual also became the chief inspector at the newly certificated repair station. While under the chief

inspector's direction, employees of the newly certificated station performed improper maintenance on a number of propellers, one of which came apart in flight causing a fatal accident.

As a result of this incident, the NTSB, in a safety recommendation dated February 9, 2004 (A-04-01 and A-04-02), expressed concern that the FAA did not have a mechanism for preventing individuals who were associated with a previously revoked repair station from continuing to operate through a new repair station.

The FAA already has such a mechanism in place for air carriers and commercial operators. Section 119.39(b) allows the FAA to deny an application for a part 121 or 135 air carrier certificate or operating certificate based on prior relevant enforcement action. The FAA can deny certification to an applicant who is substantially owned by (or intends to fill a management position with) an individual who had a similar interest in a certificate holder whose certificate was (or is being) revoked when that individual materially contributed to the circumstances causing the revocation process.

The FAA proposes new language (in § 145.1051(e)) to detail conditions under which a person may be denied a repair station certificate. The changes the FAA propose are based to a large extent on the language contained in § 119.39(b). The FAA's proposal would authorize the agency to deny a repair station application if:

• The applicant previously held a repair station certificate that was revoked.

• The applicant intends to fill or fills a management position with an individual who exercised control over or who held the same or a similar position with a certificate holder whose repair station certificate was revoked, or is in the process of being revoked. That individual must have materially contributed to the circumstances causing the revocation or causing the revocation process.

• An individual who would hold a management position previously held a management position with a certificate holder whose repair station certificate was revoked, or is in the process of being revoked. The individual must have materially contributed to the circumstances causing the revocation or causing the revocation process.

• An individual who would have control over or substantial ownership interest in the applicant had the same or similar control or interest in a certificate holder whose repair station certificate was revoked, or is in the process of being revoked. That individual must have materially contributed to the circumstances causing the revocation or causing the revocation process.

The current regulations (§ 145.55(a)) contemplate the holder of a repair station certificate voluntarily surrendering the certificate to the FAA, in which case it would cease to be effective. This voluntary surrender provision is sometimes abused in an attempt to thwart an ongoing investigation. The FAA is aware that sometimes after an enforcement investigation has commenced, the certificate holder will attempt to surrender the certificate as a means of stopping the enforcement action. It is the FAA's policy, however, not to accept the voluntary surrender of a certificate in those circumstances. The FAA's Compliance and Enforcement Program (FAA Order 2150.3B at Ch 5, Para. 10(b)) instructs FAA investigative personnel to refuse the voluntary surrender of a certificate if it appears the surrender is being attempted to avoid a certificate action. In those cases, the investigative personnel are to continue with the investigation and recommend enforcement action, if appropriate. As discussed in paragraph f (Duration and Renewal of Certificate (current § 145.55/proposed § 145.1055)) below, the FAA is proposing to amend the text currently in § 145.55 to add a new condition to the certificate surrender provision—that acceptance for cancellation by the FAA of a certificate offered for surrender is necessary to render the certificate no longer effective. This change would highlight and provide additional notice to the holders of repair station certificates of the FAA's policy against potential violators merely surrendering their certificates to avoid enforcement action. Unless the FAA accepted the certificate for surrender, it would remain effective for administrative and enforcement purposes, even if the certificate holder ceased operations. Accordingly, in the event of an enforcement action that might result in the suspension or revocation of a repair station certificate, the enforcement process could continue and, in the case of a revocation, a record would exist to support the certificate denial provisions proposed in this paragraph.

The FAA recognizes that the proposed language does not contain an appeal or reconsideration procedure. This is because a process already exists in current § 13.20, which addresses, among other things, orders of denial. Paragraph (b) of that section provides, in pertinent part, that unless an emergency exists requiring the immediate issuance of an order of denial, the affected person (the applicant) must be provided with notice prior to issuance of an order of denial. Paragraph (c) further provides that, within 30 days after service of the notice, the affected person may reply in writing or request a hearing in accordance with subpart D of part 13. Subpart D of part 13 provides the Rules of Practice for FAA Hearings. Thus, applicants who are denied a repair station certificate would be provided with appropriate due process through the means of an evidentiary hearing.

e. Issue of Certificate (Current § 145.53/Proposed § 145.1053)

Current § 145.53(a) states that, subject to three exceptions, a person who meets the requirements of part 145 is entitled to a repair station certificate with appropriate ratings prescribing such operations specifications and limitations as are necessary in the interest of safety. Since proposed § 145.1051 would provide a mechanism for the FAA to deny a certificate, an applicant would no longer be “entitled” to a certificate.

The FAA is proposing in § 145.1053(a) that an applicant could be found “eligible to be issued” a certificate. This proposed change is consistent with other certification requirements, such as in parts 121 and 135, where the FAA has the authority to deny a certificate. In addition, the FAA proposes to remove the three exceptions from this paragraph as they refer to additional requirements for particular applicants, not exceptions to the eligibility requirements.

Section 145.53(b) sets forth the procedure to certify repair stations located in a country with which the United States has a bilateral aviation safety agreement. This procedure is based on the certification from the civil aviation authority of the country that the applicant meets the requirements of part 145.

The FAA must consider that the United States may enter into a bilateral agreement with a civil aviation authority other than a national aviation authority. This situation already exists in Europe. The European Union formed the European Aviation Safety Agency (EASA) to carry out those civil aviation safety functions that were previously the domain of national aviation authorities.

Therefore, the FAA is proposing in § 145.1053(b) to allow the FAA to certify a repair station outside the U.S. based on a certification from an authority acceptable to the FAA. This change would allow the FAA to make the finding based on a recommendation from a national aviation authority, EASA, or any other EASA-like entity that may be created in the future.

f. Duration and Renewal of Certificate (Current § 145.55/Proposed § 145.1055)

As discussed in paragraph d (Application for Certificate—Denial (proposed § 145.1051(e)) above, the FAA has experienced instances in which a certificate holder surrendered its certificate to the FAA in order to stop an investigation that the holder suspected would lead to an FAA order suspending or revoking the certificate because of known or suspected serious violations of the regulations. In the case of a repair station, the holder of a repair station certificate could attempt to take advantage of the provision in current § 145.55, regarding surrender of the certificate. Upon surrender the certificate would no longer be effective, and there would be no certificate that could be suspended or revoked. This is an abuse of the surrender provision, as it was never intended as a device to stop an investigation and possible enforcement proceeding. In proposed § 145.1055, the FAA would add a new condition to rendering a surrendered certificate ineffective. Under the proposal, a surrendered certificate would remain effective unless the FAA accepted it for cancellation.

As the discussion in paragraph d points out, the FAA's Compliance and Enforcement Program (FAA Order 2150.3B at Ch 5, Para. 10(b)) instructs FAA investigative personnel to refuse the voluntary surrender of a certificate if it appears the surrender is an attempt to avoid a certificate action. The amendment proposed here would provide additional notice to all holders of repair station certificates that successfully surrendering a repair station certificate for cancellation requires not only the offer of surrender, but also the FAA's acceptance of that offer. As we noted above, unless and until the FAA accepts for cancellation a surrendered certificate, the certificate would remain effective for administrative and enforcement purposes, even if the holder ceased operations.

Current § 145.55(c) sets forth what a certificated repair station located outside the United States must provide to renew its certificate. In addition to the items listed in that provision, a certificated repair station located outside the United States must pay a fee for service as a condition for renewal. The requirement to pay this fee as part of the renewal application is not in § 145.55(c) even though it is a requirement found in 14 CFR part 187. The FAA is proposing in § 145.1055(c)(3) that, as a condition of renewal, the fee prescribed by the FAA has been paid.

g. Capability List (Current § 145.215/Proposed § 145.1215)

During the repair station certification process, an applicant's ratings are established following a demonstration to the FAA that the applicant is capable of performing maintenance on specific articles. Following certification, the FAA expects that a repair station continues to manage and control its capabilities on each individual article it maintains. This is accomplished by the repair station ensuring that it has, for example, trained personnel, and the necessary data, facilities, and equipment.

Under the current Limited rating, a repair station is required to document each article it maintains on either a capability list, or on the repair station's operations specifications. For Class ratings, the FAA assumes that a repair station, using its own methods, manages its capabilities with the same level of detail (although this is not required). Under this Class rating system, what an individual repair station is actually capable of maintaining is for the most part known only to the repair station and the individual FAA principal inspector(s) assigned to manage that repair station's certificate.

The FAA believes it is critical that both a repair station and the FAA are able to identify the actual certified capabilities of that repair station at any given time. It is important that the actual capabilities of a repair station are documented and that the documentation is current. The 2006 NPRM was not clear as to how the articles should be listed on the capability list. The FAA is proposing to define what is required on the capability list by adding two terms. The first, “series as applicable,” would recognize that not all models have series. The second, “basic part number,” would be added to clarify that it is not necessary to list each model or part “dash number.” The requirements for identifying articles on the capabilities list would provide clarity, consistency, and flexibility.

If the repair station chooses to use a capability list, the proposed rule would require that it identify each airframe, powerplant, or propeller by manufacturer, model, and series as applicable. For a component rating, the proposed rule would require that the list identify each component for which the repair station is rated by manufacturer, manufacturer-designated nomenclature, and basic part number.

Currently, it is required that this level of documentation exists for each repair station with a Limited rating. The documentation is either on a capability list or listed on the repair station's operations specifications. For all ratings under the current rule, including Class ratings, a repair station must ensure that it has the housing, facilities, equipment, material, technical data, and trained personnel in place prior to performing maintenance on an article. To make this determination today, a repair station must be aware of the manufacturer, model, series, nomenclature, and basic part number, for example, of each article it wishes to maintain. Otherwise, the repair station would not know what data to obtain, what subjects to train personnel in, and what equipment to purchase.

The current practice of issuing Class ratings was found to have limitations and unforeseen consequences that were not apparent until the advent of new technology components and aircraft. Class ratings entitled repair stations to work on articles neither they nor the FAA ever envisioned would exist at the time the rating was issued. That the repair station would limit itself from working on certain articles for which it was not fully capable essentially provided, in effect, a limited Class rating. This proposed rule would eliminate Class ratings and require the “writing down” of this identifying information in a standard format for all repair stations. From this perspective, the FAA believes the burden on the industry would be an administrative one, in particular for those currently holding a class rating. However, the burden should be, for the most part, limited to the onetime transfer of the capability list to a standard format acceptable to the FAA. The FAA requests specific comments, observations, and suggestions regarding the elimination of class ratings.

To ease this burden and to standardize the method used to document capabilities, the FAA may develop a web-based capability list. The FAA believes that an FAA-hosted automated capability list, if created, should have a positive impact on FAA staff and resources. Currently, a certificated repair station with a Limited rating has the option to list the articles for which it is rated on a capabilities list, and to expand that list through a self-evaluation process. Under this proposed rule, all repair stations could proceed in one of two ways to add an article to their capabilities list. First, a repair station could submit a request to the FAA for approval. The request would have to document that the repair

station is capable of performing the requested work—it would have to demonstrate that it has the technical data, housing, facilities, equipment, material, processes, and trained personnel to perform the work on the article for which it seeks approval. Second, either during the repair station's initial application process, or later through an amendment to its operations specifications in accordance with proposed § 145.1058, the repair station could seek a general authorization in its operations specifications to perform a self-evaluation each time it wishes to add an article to its capabilities list. Similar to the criteria used in the individual request to the FAA method discussed in option one, the self-evaluation would be done to determine that the repair station has the technical data, housing, facilities, equipment, material, processes, and trained personnel to perform the work on the article it wishes to add to its capabilities list. If the self-evaluation determines that those criteria are met, the repair station could add the article without specific FAA approval.

The FAA considers the capabilities list self-evaluation process to be similar in concept to the self-evaluation process expected under the current Class ratings system. Both processes allow for a repair station to add to its capabilities list independent from FAA review. It is not the FAA's intent to reduce this flexibility with this proposed rule. However, under the current rule, Class ratings should not be authorized unless the repair station can prove the capability to maintain a representative number of products under the rating. Unlike the Class rating which considers a repair station's ability to maintain a range of product models, the proposed capability list self-evaluation authorization would take into account the adequacy of a repair station's quality control system to control the expansion of its capabilities independent from FAA review. A risk-assessment process would be used by the FAA to evaluate a new repair station applicant's ability to manage a self-evaluation program. Existing repair stations using a capability list and those with Class ratings could be authorized to perform self-evaluations for future capability changes and would not be required to reapply for this authorization. During the 24 months of the transition period, there would be no requirement for existing repair stations to perform self-evaluations on their current capabilities beyond what is contained in their current procedures.

Proposed § 145.1215(f) would require each repair station with a capability list to review its capabilities at least every two years, and to remove any article from the list that it is no longer capable of maintaining. The FAA believes this is a necessary quality element to ensure a repair station's capability list continually reflects its actual repair station capabilities.

h. Contract Maintenance (Current § 145.217/Proposed § 145.1217)

The FAA placed this section, Contract Maintenance, under the discussion of the proposed certification requirements because a repair station's contracting capability must be understood and evaluated during the certification of the repair station.

With the exception of a new paragraph (b)(4), and an expansion of the restrictions in paragraph (c), the proposed changes in this section are made to clarify the intent of the current rule. As in the current rule, proposed § 145.1217(a) allows a repair station to contract a “maintenance function” to an outside source provided certain conditions are met. Much confusion exists around the term “maintenance function” and when FAA approval is required when a repair station contracts such a function to an outside source.

The FAA does not approve who a certificated repair station contracts with. While this information must be maintained and made available to the FAA, each repair station is free to choose with whom it contracts. However, the rule currently requires, and this proposed rule would continue to require, that the FAA approve the maintenance function to be contracted. The basis of this requirement extends back to the original certification of the repair station. When an applicant applies for a rating, the applicant must declare what functions within the rating the repair station will contract out.

For example, an applicant for a Component rating to overhaul a specific fuel pump model may not be capable of rewinding armatures and may plan to contract this function out. Although the Component rating is a blanket authorization to overhaul the pump, the applicant has formally declared what functions within the rating it will contract out—in this case, armature rewinding. Another example would be an applicant for an Airframe rating who does not plan on developing capabilities for component overhaul and repair. The function contracted out would be component overhaul and repair. Proposed §§ 145.1217(a)(1) and 145.1209(e)(5) would continue to require the certificated repair station to maintain this contracted function information for the duration of the repair station certificate.

The overriding intent of current § 145.217(a)(1), and proposed § 145.1217(a)(1) is not for the FAA to restrict the ability of a repair station to contract out maintenance, but rather to ensure the repair station's capabilities are clearly stated at all times. Nevertheless, as currently provided in § 145.217(c) and in proposed § 145.1217(c), the FAA will not approve the contracting out of all maintenance functions encompassed in the repair station's rating. Such a practice would effectively render the part 145 certificate meaningless.

Clarification is needed as to what is not contract maintenance. Part 145 does not regulate the “brokering” of a complete article by a repair station. If a repair station is not exercising the privilege of its certificate, it is not contracting a maintenance function as covered by the proposed rule. A repair station can, as can any other certificated or noncertificated person, receive, ship, arrange for maintenance, or act as agent in the brokering of maintenance for others without being considered to be contracting maintenance. When a repair station exercises the privilege of its certificate by engaging in maintenance for which it is rated, and then initiates the involvement of another person in that maintenance, the repair station is engaging in contract maintenance.

For example, if a repair station with an Airframe rating removes an engine and ships the engine to a repair station with a Powerplant rating, it is not engaging in contract maintenance because it is not rated to perform powerplant maintenance. However, if during inspection it discovers a damaged engine mount, and subsequently sends the engine mount to another repair station or noncertificated facility for a weld repair and approves the work for return to service, it would be contracting maintenance under the repair station rating (see proposed § 145.1217). The repair station is contracting maintenance because, under its rating, it is authorized to do the work and approved it for return to service. Therefore, the repair station is exercising the privilege of its certificate in performing maintenance and it is rated for the weld repair by virtue of its Airframe rating.

Throughout § 145.217, the terms “outside source”, “outside facility”, and “facility” are used interchangeably. These terms are undefined and subject to inconsistent usage and confusion. For consistency and to eliminate confusion, the FAA proposes to replace these

undefined terms in proposed § 145.1217 with the term “person,” which is defined in § 1.1.

The FAA is proposing in § 145.1217(b)(1) to add a reference to the quality control system procedures proposed in § 145.1211(c)(1)(vi) to emphasize that the quality control system of each noncertificated person with whom a repair station contracts a maintenance function must be equivalent to its own. The contracting repair station must physically observe the quality control system of each noncertificated person with whom it wishes to contract and determine that it meets this standard before any maintenance is performed by that person.

The FAA is also proposing a new provision (§ 145.1217(b)(4)) to the contracting rule to emphasize specifically that the personnel requirements set forth in proposed § 145.1151(c) apply when maintenance is contracted to a noncertificated person. Current § 145.151(c) provides that each repair station must ensure that it has a sufficient number of qualified employees to ensure all work is performed in accordance with part 43. While it is implicit in that rule that those personnel requirements apply when work is contracted to noncertificated persons (because the contracting repair station is responsible for determining the airworthiness of articles before approving them for return to service), the FAA is proposing for clarity to add a phrase in proposed § 145.1151(c) specifically referring to work contracted to a noncertificated person.

To adequately perform the surveillance and verification requirements of § 145.1217(b), a certificated repair station would need a sufficient number of employees with the training or knowledge and experience in the maintenance function performed by the noncertificated person. This is necessary to assess the noncertificated person's ability to correctly perform the work and the proper completion of the work. In contracting a maintenance function to a noncertificated person, a repair station is not absolved from having corporate technical knowledge of the work performed under its rating. If it is not able to ensure such knowledge base in its employees, a repair station must be limited from, and broker the maintenance function to, a person appropriately certificated to perform and approve the work for return to service.

4. Repair Stations Providing Maintenance for Air Carriers (Current § 145.205/Proposed § 145.1205)

Current § 145.205 contains, and proposed § 145.1205 would contain, the regulations covering maintenance, preventive maintenance, and alterations performed for certificate holders under parts 121, 125, and 135, and for foreign air carriers or foreign persons operating U.S.-registered aircraft in common carriage under part 129.

a. “Applicable Sections” of a Maintenance Manual (Current § 145.205(a)/Proposed § 145.1205(a))

Currently, § 145.205(a) states that a repair station working for an air carrier or a commercial operator that has a continuous airworthiness maintenance program under part 121 or part 135 must follow the carrier's or commercial operator's program and “applicable sections of its maintenance manual.” Before the 2001 final rule, § 145.2 specified the additional requirements for repair stations performing maintenance work for air carriers or commercial operators under the continuous airworthiness requirements of parts 121 and 127 and for airplanes under the inspection program required by part 125. The FAA believed that parts of the regulation were difficult to follow because, for example, it required repair stations to comply with identified subparts,
e.g.,
“subpart L of part 121” (
except
for certain specified sections). In an attempt at clarity, in the 1999 NPRM the FAA proposed reversing that logic and, in proposed § 145.7, instead of listing the exceptions, the proposed rule identified the specific sections that, “as applicable,” would apply (
e.g.,
“Each certificated repair station * * * must, as applicable, comply with * * *” the specified sections as listed.). That proposal also generated adverse comments. The references to the various specified sections in parts 121 and 135 “as applicable” continued to confuse some commenters, some of whom also incorrectly inferred that the FAA intended to impose additional requirements by listing specific sections of the rule.

Based on these comments, the specific section references were not included in the 2001 final rule. These air carrier maintenance provisions are currently found in § 145.205 and, generally speaking, require repair stations to follow the air carrier's or operator's program and “applicable sections of its maintenance manual.” Repair stations that provide this type of work have stated that the term “applicable sections” causes confusion because it is subjective and vague. They point out that air carriers, air operators, and the FAA's inspectors interpret the term differently. Commenters to the 2006 NPRM voiced similar concerns for similar reasons with the change proposed there. Specifically, we proposed that repair stations must comply with “the applicable parts of this chapter and follow the air carrier or commercial operator's program and applicable sections of its maintenance manual.” The confusion expressed by the commenters carries a common theme, all involving the reference to “applicable sections” or “as applicable.”

In proposed § 145.1205(a), we are attempting to clarify this issue by stating that when a repair station performs work as a maintenance provider for an air carrier or commercial operator, the repair station must perform that work in accordance with the instructions provided by that air carrier or air operator.

b. Certificate Holders Operating Under 14 CFR Part 125 (Current § 145.205(b)/Proposed § 145.1205(b))

In proposed § 145.1205(b), the FAA would change the language currently in § 145.205(b) to include all operators that may have an approved aircraft inspection program. Currently, § 145.205(b) references only FAA-approved inspection programs for part 125 operators. However, some persons operating under part 135 may also have an FAA-approved inspection program and others may have selected an inspection program under § 91.409(e). Therefore, references to part 135 and § 91.409(e) would be included in proposed § 145.1205(b).

c. Foreign Persons Operating Under 14 CFR Part 129 (Current § 145.205(c))

If a reference to a foreign air carrier or foreign person operating a U.S.-registered aircraft under part 129 is added to proposed § 145.1205(a), it is no longer necessary to include a provision similar to § 145.205(c) in proposed § 145.1205. Each of these part 129 operators must have an FAA-approved maintenance program that must be followed by persons performing maintenance on these aircraft.

d. Line Maintenance (Current § 145.205(d))

The 1999 NPRM introduced the concept of line maintenance for repair stations. As proposed, line maintenance was intended to allow repair stations currently located at an air carrier's line station to perform simple scheduled servicing and unscheduled maintenance

that could be performed safely without the need to house the aircraft. This was intended to provide relief from the requirements of § 145.103(b), which requires a repair station with an airframe rating to have the ability to house the largest aircraft for which it is rated. This maintenance would not necessarily require housing the entire aircraft.

For reasons unstated, the 2001 final rule did not include a requirement that line maintenance be limited to those repair stations located at air carrier line stations. In addition, it introduced the concept that a repair station could perform line maintenance upon authorization by the FAA. It also included a definition of line maintenance (in § 145.3) that included “any unscheduled maintenance resulting from unforeseen events.” These additions imply that a repair station may perform `any unscheduled maintenance' without meeting the prerequisites of part 145 for an appropriate rating, simply based on the issuance of an `authorization' to perform `line maintenance' for an air carrier or commercial operator.

Line maintenance was not intended to be a rating. Rather, it was meant to be an authorization for an appropriately rated repair station. The § 145.103(b) housing requirement applies to a repair station holding an Airframe rating. Section 145.205(d) is an authorization providing relief from that requirement under limited circumstances.

However, as applied, line maintenance authorization has been granted to repair stations without the appropriate ratings or facilities because the existing language implies that it is permissible. This was a concern expressed in comments in response to the introduction of the line maintenance authorization in 2001. In addition, the line maintenance concept has also resulted in repair stations that were created simply to perform line maintenance at many geographically disparate locations, which makes it almost impossible for the FAA to reasonably perform its safety oversight function.

To rectify this situation, the FAA is proposing to eliminate the current line maintenance concept by not including a provision similar to § 145.205(d) in proposed § 145.1205.

However, the performance of maintenance that could include line maintenance would still be an available option for a repair station. A repair station could be issued a limitation to an Airframe rating to identify and limit the work the repair station could perform. This could include line maintenance. With appropriate limitations, line maintenance is simply one example of work for which a limitation to an Airframe rating could be issued. With a limitation of line maintenance for a specified air carrier or commercial operator, the repair station would be permitted to perform maintenance limited to line maintenance, but there would be no authorization for line maintenance beyond the limitation to the rating.

If the line maintenance work is to be accomplished temporarily away from the repair station, this could be accommodated under the provisions of § 145.1203 (Work Performed at Another Location). If the location is in the United States and intended to be permanent, and is within the geographical boundaries of the local FAA Certificate Holding District Office, an additional fixed facility of the repair station as provided by proposed § 145.1103(d) may be appropriate. If the location is not within the geographical boundaries of the Certificate Holding District Office, certification of a separate repair station or satellite repair station under proposed § 145.1107 may be appropriate. This would reintroduce the original intent that this type of work would be limited to currently certificated repair stations at such locations where the work is needed.

The current definition of line maintenance does not correctly describe the scope of this level of maintenance. Therefore the FAA is also proposing to revise the definition of line maintenance in proposed § 145.1003(e). The definition would now reinforce that line maintenance is performed for air carriers, is generally performed at the ramp, parking area or gate, and typically will not exceed 24 continuous hours per aircraft.

5. Other Proposed Changes

a. Applicability (Proposed § 145.1001)

A new applicability statement is necessary to address the transition period. This language would direct applicants to subparts F through J for the regulations that would apply to them. This new section would continue to state that a repair station certificate is issued for the performance of maintenance, preventive maintenance, and alterations on civil products to which part 43 applies. The FAA cannot compel a person to hold a repair station certificate, so the phrase in current § 145.1
or is required to hold
would be deleted as unnecessary. The FAA proposes instead that the rules would apply to any person who holds out as an FAA-certificated repair station.

b. Avionics (Proposed § 145.1003(c))

Aviation electronic technology has advanced dramatically since the advent of the current ratings system. Because of these advancements, the ARAC recommended the addition of an avionics rating. The FAA proposed such a rating in the 2006 NPRM. The commenters generally opposed a separate avionics rating. Most of these commenters stated that avionics are components and should simply be identified as such. Moreover, other commenters stated that confusion would exist if avionics were made a separate category of component.

To recognize advances in the field of aviation electronics and to reduce any confusion that exists regarding the differences and overlaps in the terms instruments, electronics, electrical systems, and avionics, the FAA is proposing to add a definition for the term “Avionics” in proposed § 145.1003(c). Under this definition, “Avionics” (i.e., aviation electronics) would be any component generally associated with processing digital electronic signals. Examples of such components include radios and navigation equipment, radar, and data processors.

c. Repair Station Records: Falsification, Reproduction, or Alteration (Proposed §§ 145.12 and 145.1012)

At present, part 145 does not contain a general prohibition against making fraudulent or intentionally false entries in repair station records or for making fraudulent reproduction or alteration of records or reports. Other parts of the regulations do contain similar proscriptions. For example, part 43 contains such prohibitions for maintenance records or reports, with a consequence of suspension or revocation of the applicable airman, operator, or production certificate and other specified privileges (see § 43.12.). Other regulations contain similar prohibitions (
e.g.,
intentionally false entries on applications and other records, and cheating on tests) with similar consequences (i.e., suspension or revocation of FAA-issued certificates or ratings (see.
e.g.,
§§ 61.37, 61.59, 63.18, 63.20, 65.18, 65.20, and 67.403.)). While § 43.12 provides for suspension or revocation of the applicable airman and other mentioned certificates and privileges for requisite maintenance record falsifications or fraudulent acts, it does not provide for repair station certificate suspension or revocation for the same kind of conduct.

Therefore, the FAA is proposing a new § 145.12 in subpart A, and a new

§ 145.1012 in subpart F, that would be similar to § 43.12. Under 49 U.S.C. 44701, the FAA is charged with promoting aviation safety. The importance of accurate records and reports cannot be overstated. In view of the FAA's limited resources, “the agency, and ultimately the flying public, depend heavily on the integrity of the system of self-reports.”
Twomey
v.
National Transp. Safety Bd.,
821 F.2d 63, 68 (1st Cir. 1987). Because of the importance of honest and trustworthy records and reports to aviation safety, the FAA believes that any person who makes or causes to be made an intentionally false or fraudulent entry in any record or report the agency needs to provide proper oversight of repair stations should be subject to enforcement action as noted above. Accordingly, the agency is proposing suspension or revocation of not only the repair station certificate, but any certificate, approval, or authorization issued by the FAA and held by that person.

d. Amendment to or Transfer of Certificate (Current § 145.57/Proposed § 145.1056)

Although the one thousand series numbers (1xxx) in proposed subparts F through J generally have the same one hundred series number (xxx) for each corresponding regulation section in the current rule (subparts A through E), the FAA is proposing to deviate from this scheme for this section in order to accommodate two new proposed sections on operations specifications. Therefore, the proposed new section on “Amendment to or transfer of certificate” would be numbered § 145.1056, whereas the current section is numbered § 145.57. The proposed section captioned “Operations specifications” would be numbered § 145.1057. Also, as written, current § 145.57 contains confusing language that implies a repair station must apply for a change to its certificate without reason. The proposed section would change the confusing language and add a time limitation for submitting an application for a certificate amendment, change in location, or transfer of certificate.

e. Operations Specifications (Proposed § 145.1057)

Currently, part 145, Repair Stations, introduces the requirement for operations specifications in § 145.5, Certificate and operations specification requirements. Unlike other operating rules requiring operation specifications, part 145 does not explain what operation specifications are or what they must contain. Also unlike part 119, which clearly states in § 119.7 that with limited exceptions operations specifications are not a part of the certificate, some operators and FAA personnel assume repair station operations specifications are an extension of the repair station certificate, while others do not. The FAA is proposing to specify how long operations specifications are valid, what they must contain, and where they must be located. The FAA would also clarify that except for those operation specifications detailing ratings and limitations, repair station operations specifications are not a part of the repair station certificate.

f. Amending Operations Specifications (Proposed § 145.1058)

The proposed clarification of operations specifications in proposed § 145.1057, specifying that operations specifications are not a part of a certificate, would allow the FAA to make administrative changes to operations specifications other than ratings or limitations (
e.g.,
definitions or formatting) without having to resort to certificate action, when appropriate notice is given to the repair station. This section would provide procedures to be followed by both the FAA and repair stations for initiating changes to the operations specifications. Additionally, procedures would be provided for affected repair stations to petition for reconsideration of adverse decisions by the FAA, both in emergency and non-emergency situations.

g. Housing and Facilities (Current § 145.103/Proposed § 145.1103)

The FAA is proposing to amend the rules for housing and facilities to require that the housing for the facilities, equipment, materials, and personnel be both suitable and permanent. The agency is also proposing to provide an exception to the requirement that a repair station with an airframe rating must be able to enclose the largest type and model of aircraft on its operations specifications to facilitate those with a limitation to the airframe rating such that the entire aircraft would not need to be housed to provide appropriate environmental protection. As stated previously, this exception would facilitate repair stations with a limitation to perform line maintenance for air carriers. Finally, in addition to some minor clarifications, the FAA is proposing to allow a repair station to use multiple fixed locations if appropriate criteria are met.

i. Exception to Housing Requirement

Under current § 145.103(b), a certificated repair station with an Airframe rating must provide suitable permanent housing to enclose the largest type and model of aircraft listed on its operations specifications without consideration of the limits of the work being performed. Even if the work is limited to a certain part, portion, or section of the aircraft, a repair station must be able to house the entire aircraft if it has an Airframe rating.

To retain the level of safety established by certification of a repair station under part 145, but to lessen the impact to those repair stations performing line maintenance or other maintenance not normally associated with a requirement to have housing to enclose the entire aircraft, the FAA is proposing, in § 145.1103(b), to provide relief from the housing requirement of § 145.103(b). The proposed change would allow a repair station with an Airframe rating and appropriate limitations to that rating to perform the limited airframe maintenance without having housing to enclose the entire aircraft. If, as determined by the FAA, the repair station provides adequate environmental protection for the work being performed under the limitation to its rating, it would not be required to house the complete aircraft.

This is consistent with the housing exception for line maintenance found in § 145.205(d). The proposed rule permits an evaluation of the housing requirements based on limitations to the Airframe rating. This would allow for the certification of a repair station with an Airframe rating, limited to the performance of maintenance such as simple daily scheduled checks or some work limited to aircraft interiors, to not have housing to enclose the entire aircraft. Repair stations currently performing work under a line maintenance authorization could be provided appropriate housing relief by this proposed section if they otherwise meet the requirements of part 145. This change would provide clarity and some relief in not requiring that the entire airframe be enclosed if the FAA determines the repair station provides adequate environmental protection for the work being performed. This option would be available only for repair stations with an Airframe rating with limitations. If a repair station has an Airframe rating with no limitations or limitations allowing work on substantially an entire airframe, it would be required to have suitable permanent housing to enclose the largest aircraft for which it is rated.

ii. Permanent Location

Paragraph (a)(1) of § 145.103 requires each certificated repair station to provide housing for the facilities, equipment, materials, and personnel consistent with its ratings. It has long been FAA policy that a repair station must have a permanent fixed location from which to operate. There have been occasions where the housing used to obtain certification was either relinquished by the certificate holder to the facility owner, or further sub-leased for other purposes rendering the repair station essentially unable to perform the maintenance for which it was certificated. The FAA believes it is necessary to reinforce the need for repair stations to provide assurance that work is performed adequately and to the manufacturer's standards. This means protection of workers from unfavorable environmental conditions so that their performance and the airworthiness of the articles they are maintaining are not adversely affected. Repair stations would be required to provide suitable and permanent housing to protect the articles being maintained from contamination, foreign object debris, or conditions that may promote corrosion or other deteriorating conditions.

Therefore, the FAA proposes to revise this section to require “suitable permanent” housing. A requirement for permanent housing refers not only to the construction of the facility, but also to the fact that the certificate holder must have sole operational control at all times of the housing it uses to obtain certification, either by ownership or by contract. The FAA understands that repair stations may share the same hangar or building, and this would still be allowed under this proposal. However, these repair stations may not share the same space in that hangar or building and each repair station must have full control of its space at all times. In addition, it must be clearly defined as to what space is under the control or contract of each repair station and this space must be clearly defined in each repair station's manual as required in proposed § 145.1209(b).

iii. Multiple Fixed Locations

The FAA is also proposing to add a new § 145.1103(d) to allow a repair station to use multiple fixed locations in performing maintenance, preventive maintenance, and alterations under its repair station certificate. Additional fixed locations are not recognized in the current rule. This has led to inconsistent or non-authorization of the use of additional permanent locations. Repair stations often find it necessary to use locations other than the primary facility for environmental reasons (such as noise abatement for an engine overhaul shop doing test runs). In recognition of this need, additional fixed locations could be authorized if:

• The repair station applies for and receives approval of additional fixed locations.

• The location is within the geographic boundaries of the certificate holding district office.

• The location is permanently affixed and is under the managerial control and authority of the repair station certificate.

• The maintenance functions performed at the additional fixed locations are in support of and within the scope of the ratings listed on the repair station operations specifications.

If a fixed location were located outside of the geographic boundary of the FAA office with oversight responsibilities, the additional fixed location either would have to be certificated as a satellite repair station and meet the requirements of proposed § 145.1107, or it would require its own repair station certificate under the provisions of proposed § 145.1051 and § 145.1053.

iv. Additional Proposed Changes

The FAA is also proposing, in § 145.1103(a)(2), to delete the reference to specialized services currently found in § 145.103(a)(2). When used in conjunction with maintenance, preventive maintenance, and alterations, the reference to specialized services is redundant because complete maintenance of an article includes all necessary services. Finally, the FAA is also proposing to include protection of articles in § 145.1103(a)(2)(iv). Currently, a repair station's facility is required to include sufficient space to segregate articles and materials stocked for installation from those undergoing maintenance or alterations. The FAA is proposing to change “segregate articles * * * ” in current § 145.103(a)(2)(iv) to “segregate and protect articles * * *.” in § 145.1103(a)(2)(iv) to be consistent with the intent not only to segregate but also to protect articles as stated in current § 145.103(a)(2)(i) and in proposed § 145.1103((a)(2)(i) “for the proper segregation and protection of articles during all maintenance, preventive maintenance, or alterations.” It is inconsistent to require articles to be protected during maintenance but not require them to be protected in storage prior to being used in maintenance.

To ensure that the housing and other environmental protections continue in force, the FAA is proposing to change the phrase in the first line of § 145.103(a) from “repair station must provide-* * *” to “repair station must provide
and maintain
- * * *” in proposed § 145.1103(a).

Finally, a grammatical error currently exists in § 145.103(a)(2)(ii) that the FAA would correct in proposed § 145.1103(a)(2)(ii) by adding the word “of” near the end of the sentence so that it reads “alteration of articles * * *.”

h. Satellite Repair Stations (Current § 145.107/Proposed § 145.1107)

In proposed § 145.1107(a), the FAA proposes to remove the current restriction in § 145.107(a)(1) that a satellite repair station may not hold a rating not held by the certificated repair station with managerial control. The FAA believes that the agency should not impose these restrictions on satellite repair stations.

Additionally, the FAA proposes to require that an applicant for a satellite repair station submit the same repair station and quality control system manuals as the repair station with managerial control (proposed § 145.1107(a)(2)). The satellite repair station would have to identify any specific processes or procedures unique to the satellite repair station in appendices or sections of the manuals.

The other new paragraphs proposed in § 145.1107(a) would require a satellite repair station to:

• Submit the same training program as the repair station with managerial control, with processes or procedures unique to the satellite or managerial repair station identified (proposed paragraph (a)(3)).

• Demonstrate compliance with its manual and any additional manual sections applicable to the satellite (proposed paragraph (a)(4)).

• Meet the housing and facility requirements of proposed § 145.1103 since it is a separately certificated repair station (proposed paragraph (a)(5)).

• Have its own facility in a location with a physical address other than the repair station with managerial control (proposed paragraph (a)(6)).

Finally, the requirement currently in § 145.107(a)(2) that the satellite repair station meet the requirements for each rating it holds would be retained in proposed § 145.1107(a)(1).

i. General (Current § 145.101/Proposed § 145.1101)

The FAA proposes to add tools and test apparatus to the items that a repair station must provide under proposed § 145.1101. Tools and test apparatus are added for consistency with the maintenance performance requirements of § 43.13(a).

The FAA also proposes to add the word “any” to near the end of the sentence so that it reads “any rating the repair station holds.”

j. Equipment, Materials, and Data Requirements (Current § 145.109/Proposed 145.1109)

The FAA is proposing to add test apparatus and data to the list of items that a repair station would have to have on the premises and under its control when it is performing work requiring its use. This would remove potential uncertainty surrounding whether a necessary piece of test apparatus or data was considered to be “equipment,” “tools,” or neither. In addition, including test apparatus would be consistent with the requirements in § 43.13(a). Accordingly, the FAA is proposing to revise the section heading to include test apparatus.

The FAA is also proposing to include an element of the relief provided in current § 145.51(b) pertaining to meeting the equipment requirement by having a contract with another person to make the equipment available when the work it requires is being performed (see proposed § 145.1109(b)). The issue of whether all the equipment must be on site for initial inspection was discussed above in the context of the agency's proposing to delete the contract provision from the initial certification requirements in proposed § 145.1051(b). Although the agency believes it is important during initial certification to observe all the necessary equipment, tools, and apparatus for its placement on site and to evaluate an applicant's ability to use it, the FAA agrees with previous commenters who voiced concerns about not having to purchase expensive, seldom used equipment and to have it permanently in place when they could instead obtain it through contract when needed.

The relief proposed in § 145.1109(b) would allow a repair station to meet the equipment, tools, and test apparatus requirement of proposed § 145.1109(a) for specialized and rarely used equipment, tools, and test apparatus if the repair station demonstrates to the FAA that it has made arrangements with another person to make those items available when their use is required. All equipment must be in place during the demonstration and inspection phase of certification.

Currently, § 145.109(d) lists certain documents that repair stations must keep that are necessary for performing maintenance, preventive maintenance, or alterations. It requires that the documents be “current and accessible when the relevant work is being done.” A strict reading of the requirement that these documents be current has created unnecessary compliance and enforcement issues. A recent FAA legal interpretation clarified that “current” in this context means “up to date,” i.e. the most recent version (revision) of the document (
e.g.
maintenance manual) issued by the manufacturer. This is a paperwork requirement only, as the same interpretation made clear that if a maintenance provider used a prior version/revision of a manual in performing maintenance, there would be no violation of the maintenance performance rules unless the FAA could show that the data used was no longer acceptable. This is so because of the flexibility provided in the maintenance regulations. For example, the performance standards set forth in § 43.13(a) provides that the person performing maintenance shall use the current manufacturer's maintenance manual or Instructions for Continued Airworthiness [ICA], “or other methods, techniques, and practices acceptable to the Administrator * * *.”

Enforcement issues have arisen because some inspectors have concluded that the requirement to have a document be “current and accessible” when work is being done means that the most up-to-the-minute manual revision be incorporated into the repair station's system even though such immediate incorporation may not be realistic. This can be due to a number of real-world constraints, (
e.g.,
mail delays, revision publishing and distribution logistics, and export constraints pertaining to technical data).

The housekeeping means for assuring appropriate compliance is contemplated in the current rule through the repair station's quality control system. Currently, § 145.211(a) requires that each repair station establish and maintain a quality control system acceptable to the FAA that ensures the airworthiness of the articles being maintained. Section 145.211(c) provides that, as part of a repair station's acceptable quality control system, the repair station must keep current a quality control manual in a format acceptable to the FAA, and specifies what that manual must include. Section 145.211(c)(1)(v) provides specifically that the manual include a description of the procedures used for “[e]stablishing and maintaining current technical data for maintaining articles.”

In developing acceptable procedures for assuring the currency of the technical data, repair stations typically work with their local Certificate Holding District Offices (CHDOs) to tailor procedures that consider realistic time constraints to incorporate manual revisions and other changes/updates into their systems. So long as a repair station and its CHDO have established and agreed to realistic procedures for establishing and maintaining current data, it would be anomalous for an inspector to threaten enforcement action citing § 145.109(d) because a manufacturer had issued a revision that the repair station had not reasonably, in following its FAA-accepted quality control system, incorporated into its manual system.

In view of these considerations, and the fact that proposed § 145.1109(a) would require repair stations to have the technical data, etc., to perform their maintenance in accordance with part 43, a specific list of documents such as that found in current § 145.109(d) would be redundant and possibly limiting. Therefore, because proposed § 145.1109(a) requires the technical data, equipment, tools, test apparatus, and materials required by part 43, we are deleting subparagraph § 145.109(d) since it is inclusive in subparagraph § 145.1109(a).

k. Supervisory Personnel Requirements (Current § 145.153/Proposed § 145.1153)

Section 145.153(a) requires supervisors to oversee the work performed by any individuals who are unfamiliar with the methods, techniques, practices, aids, equipment, and tools used to perform maintenance. The FAA is proposing to simplify this requirement to specify that supervisors must be present to oversee the work being performed by the repair station (see proposed § 145.1153(a).

Section 145.153(b)(1) requires each supervisor employed by a repair station located inside the United States to be certificated under part 65. Supervisors may supervise only as allowed by the privileges of the certificate held as provided in part 65. For example, a supervisor certificated with only a Powerplant rating may not supervise personnel doing airframe maintenance, as the Powerplant rating does not provide that privilege.

The FAA is proposing in § 145.1153(b)(1) to revise this requirement to state that the supervisor be appropriately certificated under part 65 for the work being supervised. Prior to the 2001 rule change, the language was clear in § 145.39(d): “Each person who is directly in charge of the maintenance functions of a repair station must be appropriately certificated under part 65 * * *”. The omission of “appropriately” in 2001 was an oversight that the FAA will correct by reinserting “appropriately

certificated under part 65” where such certification under part 65 is required. The appropriateness of the certificate is based in the privilege of the mechanic or repairman certificate issued under part 65 subpart D or E. For example, a supervisor who holds a mechanic certificate with airframe and powerplant ratings issued under part 65 would not be appropriately certificated to supervise work on instruments. A supervisor would need to hold a repairman certificate to supervise work on instruments. Currently, § 145.153(b)(2) contains a different set of qualifications for a supervisor employed by a repair station located outside the United States. For example, a supervisor in a foreign repair station is not required to be appropriately certificated under part 65. To eliminate these two dissimilar standards, the FAA is proposing two alternative paths for supervisor qualification in a repair station located outside the United States. The first would require the supervisor to have the appropriate certification under part 65; the second would require the supervisor to meet the repairman eligibility requirements of § 65.101(a)(1)(2)(3) and (5) (see proposed § 145.1153(b)(2)(i) and (ii)).

Finally, § 145.153(c) requires repair stations to ensure that each supervisor understands, reads, and writes English. The FAA is proposing in § 145.1153(c) that these supervisors also be able to speak English. This would help to confirm that supervisors read and understand English.

l. Inspection Personnel Requirements (Current § 145.155/Proposed § 145.1155)

Section 145.155 sets forth the experience requirements for inspection personnel. Currently, this section requires only that inspectors be able to understand, read, and write English. The FAA is proposing to add a requirement to proposed § 145.1155(b) that inspectors be able to speak English as well. As stated above, the FAA believes this would help to confirm that these inspection personnel read and understand English.

Section 145.155(a)(2) currently has the word “and” at the end of the section. This is an error as there is no § 145.155(a)(3). This error would not be carried over to proposed § 145.1155(a)(2) as the subsequent proposed § 145.1155(b) stands alone.

m. Personnel Authorized To Approve an Article for Return To Service (Current § 145.157/Proposed § 145.1157)

Section 145.157 sets forth the experience requirements for the person authorized to approve an article for return to service. Section 145.157(a) requires each person authorized to approve an article for return to service employed by a repair station located inside the United States to be certificated under part 65. For the reasons discussed above under proposed § 145.1153, the FAA is proposing in § 145.1157(b) that each person authorized to approve an article for return to service
be appropriately certificated
under part 65. The appropriateness of the certificate is based in the privilege of the mechanic or repairman certificate issued under part 65 subpart D or E.

Currently, § 145.157(b) contains a different set of qualifications for a person authorized to approve an article for return to service employed by a repair station located outside the United States. To harmonize these two dissimilar standards as much as possible, the FAA is proposing in § 145.1157(c) to require those persons employed by a repair station located outside the United States to meet either the certificate requirements of proposed § 145.1157(a) or the eligibility requirements of § 65.101(a)(1), (2), (3) and (5).

Section 145.157(c) requires that a repair station ensure that each person authorized to approve an article for return to service understands, reads, and writes English. For the reasons discussed above, the FAA is proposing in § 145.1157(d) that these persons also be able to speak English.

Finally, the FAA believes the requirements in current § 145.157 are set forth in a cumbersome manner. Therefore, the FAA is proposing to rearrange these requirements in proposed § 145.1157.

n. Records of Management, Supervisory, and Inspection Personnel (Current § 145.161/Proposed § 145.1161)

Section 145.161 sets forth the management, supervisory, and inspection personnel records that a repair station must maintain and make available to the FAA.

Section 145.161(a)(3) requires each repair station to maintain a roster of personnel authorized to sign a maintenance release for approving a maintained or altered article for return to service. To be consistent with the use of the term approval for return to service in §§ 43.5 and 43.7, and to eliminate confusion arising from the use of “maintenance release for approving an article,” the FAA is proposing to change this requirement to a roster of personnel authorized to approve for return to service a maintained or altered article (see proposed § 145.1161(a)(3)).

Section 145.161(a)(4) requires each repair station to maintain a summary of specified information on the employees listed in the rosters required by §§ 145.161(a)(1) through (a)(3). Section 145.161(a)(4)(iii) requires this summary to include past relevant employment with names of employers and periods of employment. The FAA is proposing in § 145.1161(a)(4)(iii) to require that past positions and types of maintenance performed be included in this format. This would confirm the relevancy of the listed past employment.

o. Training Requirements (Current § 145.163/Proposed § 145.1163)

Section 145.163 contains the requirements for a repair station's employee training program. The FAA is proposing in § 145.1163(a) to delete the implementation date requirements of § 145.163(a) as this is no longer applicable.

The FAA is also proposing that the training program requirements in § 145.163(b) be revised in proposed § 145.1163(b). Currently, the training program must ensure that each employee assigned to perform maintenance, preventive maintenance, or alterations, and inspection functions is capable of performing the assigned task. The FAA believes that the current requirement is too broad and lacks specific elemen
