AGENCY: Federal Aviation Administration (FAA), Department of

Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding an existing airworthiness directive

(AD), which applies to all EMBRAER Model EMB-145, -145ER, -145MR, -

145LR, -145XR, -145MP, and -145EP airplanes. That AD currently requires

repetitive inspections to detect cracking or failure of the rod ends of

the aileron power control actuator (PCA), and corrective actions if

necessary. This new AD requires the same repetitive inspections of

additional parts at new inspection intervals for certain airplanes;

provides new corrective actions; and provides an optional terminating

action for the requirements of this AD. This AD results from the

issuance of mandatory continuing airworthiness information by the

Brazilian airworthiness authority. We are issuing this AD to detect and

correct cracking or breaking of the rod ends and connecting fittings of

the aileron PCA, which could result in reduced controllability of the

airplane.

DATES: This AD becomes effective November 8, 2006.

The Director of the Federal Register approved the incorporation by

reference of certain publications listed in the AD as of November 8,

2006.

The Director of the Federal Register approved the incorporation by

reference of EMBRAER Alert Service Bulletin 145-27-A054, Change 01,

dated February 17, 1999, on March 29, 1999 (64 FR 13892, March 23,

1999).

Discussion

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14

CFR

[[Page 58488]]

part 39 to include an AD that supersedes AD 99-05-04, amendment 39-

11087 (64 FR 13892, March 23, 1999). The existing AD applies to all

EMBRAER Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -

145EP airplanes. That NPRM was published in the Federal Register on

December 7, 2005 (70 FR 72726). That NPRM proposed to continue to

require repetitive inspections to detect cracking or failure of the rod

ends of the aileron power control actuator (PCA), and corrective

actions if necessary. That NPRM also proposed to require the same

repetitive inspections of additional parts at new inspection intervals

for certain airplanes to detect cracking or failure of the rod ends of

the aileron power control actuator (PCA); provide new corrective

actions; and provide an optional terminating action for the proposed

requirements.

Comments

We provided the public the opportunity to participate in the

development of this AD. We have considered the comments that have been

received on the NPRM.

Request To Add Airplane Models to the Applicability

ExpressJet requests that we include EMBRAER Model EMB-135 airplanes

in the applicability of the NPRM. ExpressJet states that its Model EMB-

135ER and -135LR airplanes that are currently subject to an 800-flight

hour inspection interval, if subject to the AD, would be subject to a

1,000-flight hour inspection interval. ExpressJet asserts that these

airplanes should be subject to the AD because they have the same

subject parts.

We do not agree. EMBRAER Model EMB-135 airplanes should not be

subject to this AD because they already have the required structural

modifications and reinforced aileron PCA-factory incorporated since the

first production Model EMB-135 airplane. Regarding the difference in

inspection intervals, we have confirmed with EMBRAER that there is no

technical reason for the different inspection interval for Model EMB-

135 airplanes from that of the airplanes subject to this AD. The

different inspection intervals for these airplanes are a result of

different maintenance program updating processes (Maintenance Review

Board Report updating process versus a design change approval process)

used for the different airplane models. EMBRAER has notified us that it

is currently in the process of issuing a temporary revision to the

EMBRAER EMB-135 Certification Maintenance Requirements that will change

the inspection interval for those airplanes from 800 flight hours to

1000 flight hours-the same inspection interval specified in this AD for

the subject airplanes. No change to the AD is necessary in this regard.

Request To Reference Parts Manufacturer Approval (PMA) Parts

Modification and Replacement Parts Association (MARPA) requests

that the language in the NPRM be changed to identify the new,

reinforced parts by part number (P/N). MARPA states that the ``new and

improved'' parts are not identified by P/N in the NPRM and asserts

that, if they are identified by P/N in the service bulletin, the

mandated installation of a certain P/N in the NPRM ``could constitute a

conflict with 14 CFR Section 21.303.'' MARPA also requests that a

qualifying statement, ``or other FAA-approved part,'' be appended.

MARPA states that this qualification would remove the possible

``conflict'' by explicitly stating that other qualified PMA parts are

permitted.

We infer that MARPA would like the AD to permit installation of any

equivalent PMA parts so that it is not necessary for an operator to

request approval of an alternative method of compliance (AMOC) in order

to install an ``equivalent'' PMA part. Whether an alternative part is

``equivalent'' in adequately resolving the unsafe condition can only be

determined on a case-by-case basis based on a complete understanding of

the unsafe condition. Our policy is that, in order for operators to

replace a part with one that is not specified in the AD, they must

request an AMOC. This is necessary so that we can make a specific

determination that an alternative part is or is not susceptible to the

same unsafe condition. Therefore, we do not agree with MARPA's requests

and have made no change to the AD in this regard.

The AD provides a means of compliance for operators to ensure that

the identified unsafe condition is addressed appropriately. For an

unsafe condition attributable to a part, the AD normally identifies the

replacement parts necessary to obtain that compliance. As stated in

section 39.7 of the Federal Aviation Regulations (14 CFR 39.7),

``Anyone who operates a product that does not meet the requirements of

an applicable airworthiness directive is in violation of this

section.'' Unless an operator obtains approval for an AMOC, replacing a

part with one not specified by the AD would make the operator subject

to an enforcement action and result in a civil penalty. We acknowledge

that there may be other ways of addressing this issue. Once we have

thoroughly examined all aspects of this issue, including input from

industry, and have made a final determination, we will consider whether

our policy regarding PMA parts in ADs needs to be revised. However, we

consider that to delay this AD action would be inappropriate, since we

have determined that an unsafe condition exists and that replacement of

certain parts must be accomplished to ensure continued safety.

Therefore, no change to the AD is necessary in this regard.

In response to MARPA's statement regarding a ``conflict with FAR

21.303,'' under which the FAA issues PMAs, this statement appears to

reflect a misunderstanding of the relationship between ADs and the

certification procedural regulations of part 21 of the Federal Aviation

Regulations (14 CFR part 21). Those regulations, including section

21.303 of the Federal Aviation Regulations (14 CFR 21.203), are

intended to ensure that aeronautical products comply with the

applicable airworthiness standards. But ADs are issued when,

notwithstanding those procedures, we become aware of unsafe conditions

in these products or parts. Therefore, an AD takes precedence over

design approvals when we identify an unsafe condition, and mandating

installation of a certain P/N in an AD is not at variance with section

Sec. 21.303.

Request To Address Defective PMA Parts

MARPA notes that the P/Ns cited in the NPRM reflect both original

equipment manufacturer (OEM) and PMA parts ``approved by identicality

under license to Parker Hannifin Company.'' The commenter believes that

the requirements of the AD should apply equally to the OEM and PMA

parts.

We do not agree that it is necessary to specify whether an

identified part is made by the OEM or by the holder of a PMA. The P/Ns

of the affected parts are the information that is necessary to comply

with the requirements of this AD and those P/Ns are clearly identified

in the AD. Therefore, no change has been made to the final rule in this

regard.

Request To Use Serviceable Parts

ExpressJet also asks that we revise the NPRM to allow use of

serviceable parts in lieu of new parts for replacement/installation of

an aileron PCA. ExpressJet states that it completed the requirements of

this AD some time ago and that they used parts that were serviceable,

but may not have been new.

We agree. It is our policy to allow operators to use serviceable

parts in lieu

[[Page 58489]]

of new parts if a serviceable part exists and that part is not subject

to the unsafe condition addressed by the AD and will adequately ensure

long-term continued operational safety by its use. Therefore, we have

changed this final rule to allow use of serviceable parts for the

replacement/installation of an aileron PCA.

Request To Add Service Information

ExpressJet asks that we add the service information identified in

the table below as acceptable methods of compliance for the

requirements of the paragraphs also specified in the table below.

ExpressJet notes that the technical content of these service bulletins

is the same as in the later revisions already cited in the NPRM as the

appropriate sources of service information for the requirements of

those paragraphs.

We agree with ExpressJet's request. We have reviewed these service

bulletins and have determined that the technical content of each is

essentially the same as those already referenced in the NPRM for the

applicable actions. Therefore, we have added these service bulletins to

the applicable paragraphs as acceptable methods of compliance for the

applicable requirements of this final rule.

Conclusion

We have carefully reviewed the available data, including the

comments that have been received, and determined that air safety and

the public interest require adopting the AD with the changes described

previously. We have determined that these changes will neither increase

the economic burden on any operator nor increase the scope of the AD.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to

issue rules on aviation safety. 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.

We are issuing this rulemaking under the authority described in

Subtitle VII, Part A, Subpart III, Section 44701, ``General

requirements.'' Under that section, Congress charges the FAA with

promoting safe flight of civil aircraft in air commerce by prescribing

regulations for practices, methods, and procedures the Administrator

finds necessary for safety in air commerce. This regulation is within

the scope of that authority because it addresses an unsafe condition

that is likely to exist or develop on products identified in this

rulemaking action.

Regulatory Findings

We have determined that this AD will not have federalism

implications under Executive Order 13132. This AD will not have a

substantial direct effect on the States, on the relationship between

the national government and the States, or on the distribution of power

and responsibilities among the various levels of government.

For the reasons discussed above, I certify that this AD:

(1) Is not a ``significant regulatory action'' under Executive

Order 12866;

(2) Is not a ``significant rule'' under DOT Regulatory Policies and

Procedures (44 FR 11034, February 26, 1979); and

(3) Will not have a significant economic impact, positive or

negative, on a substantial number of small entities under the criteria

of the Regulatory Flexibility Act.

We prepared a regulatory evaluation of the estimated costs to

comply with this AD and placed it in the AD docket. See the ADDRESSES

section for a location to examine the regulatory evaluation.
