Airworthiness Directives; Hartzell Propeller Inc. Propellers and McCauley Propeller Systems Controllable Propellers

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to adopt a new airworthiness directive (AD) for certain Hartzell Propeller Inc. HC, BHC, and PHC series propellers; and McCauley Propeller Systems controllable propellers serviced by Oxford Aviation Services Limited, doing business as CSE Aviation, in the United Kingdom between September 1998 and October 2003. This proposed AD would require inspecting the propeller blades and other critical propeller parts for wear and mechanical damage. This proposed AD results from findings that CSE Aviation failed to perform specific inspections and repairs. We are proposing this AD to detect unsafe conditions that could result in a propeller blade separating from the hub and loss of control of the airplane.

DATES:

We must receive any comments on this proposed AD by August 15, 2005.

Discussion

On October 28 and 29, 2003, an FAA International Field Office conducted an audit of Oxford Aviation Services Limited, doing business as CSE Aviation. That audit revealed that CSE Aviation was not using the latest maintenance manuals to perform inspections and repairs. The investigators believe the discrepancies date from about 1998, when CSE Aviation stopped updating their internal procedures to reflect the latest version of the manufacture's maintenance manuals. The audit also showed that CSE Aviation did not perform specific inspections required by the maintenance manual. CSE Aviation conducted an internal investigation and confirmed that they did not perform many inspections and rework procedures such as:

• Removing damage to propeller blade balance holes.

• Shot peening the balance holes as required by the manufacturer's maintenance instructions.

Some of the other findings from the CSE Aviations internal audit were:

• Returning propellers to service with hubs involved in ground strikes.

• Incomplete or incorrectly completed overhauls of the propellers before returning to service,

• Not performing significant inspections or repairs that would have required a repair or that would have caused that product to be declared unairworthy,

Service history shows that these types of omissions of inspections and repair procedures and improperly returning to service propellers with these conditions have resulted in cracked propeller blades and hubs. These conditions, if not corrected, could result in a propeller blade separating from the hub and loss of control of the airplane.

FAA's Determination and Requirements of the Proposed AD

We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other products of this same type design. We are proposing this AD, which would require before further flight a search of aircraft and propeller records to determine if the propeller was involved in a ground strike. This proposed AD would also require disassembly, cleaning, inspection, and repair within the following compliance times:

• Within 10 flight hours (FH) time-in-service (TIS) after the effective date of this proposed AD, or 2 years after the effective date of the proposed AD, whichever is earlier, if the propeller was involved in a ground strike.

• Within 200 FH TIS after the effective date of this proposed AD, or 2 years after the effective date of the proposed AD, whichever is earlier, if the time-since-overhaul (TSO) of the propeller is more than 1,500 FH.

• Within 350 FH TIS after the effective date of this proposed AD, or 2 years after the effective date of the proposed AD, whichever is earlier, if the TSO of the propeller is more than 1,000 FH and fewer than 1,500 FH.

• Within 500 FH TIS after the effective date of this proposed AD, or 2 years after the effective date of the proposed AD, whichever is earlier, if the TSO of the propeller is 1,000 FH or fewer.

Costs of Compliance

We estimate that about 389 Hartzell Propeller Inc. HC series propellers and about 126 McCauley Propeller Systems controllable propellers of the affected design installed on airplanes of U.S. registry would be affected by this proposed AD. We also estimate that it would take about 10 work hours per propeller to perform the proposed actions, and that the average labor rate is $65 per work hour. Required parts would cost about $2,350 per propeller. Based on these figures, we estimate the total cost of the proposed AD to U.S. operators to be $1,545,000.

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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation:

1. Is not a “significant regulatory action” under Executive Order 12866;

2. Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and

3. Would 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 summary of the costs to comply with this proposal and placed it in the AD Docket. You may get a copy of this summary at the address listed under

Unsafe Condition

(d) This AD results from findings that CSE Aviation failed to perform specific inspections and repairs. We are issuing this AD to detect unsafe conditions that could result in a propeller blade separating from the hub and loss of control of the airplane.

Compliance

(e) You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.

(f) For propellers listed by SN in Table 1 or Table 2 overhauled or repaired by CSE after November 2003, or overhauled by an FAA-approved propeller repair facility after October 2003, no further action is required.

All Propellers Listed by SN in Table 1 or Table 2

(g) Before further flight, perform a document search of airplane and propeller records to determine if the propeller was involved in a ground strike.

(h) If the propeller was involved in a ground strike, perform the requirements specified in paragraph (j) or paragraph (k) of this AD within 10 flight hours (FH) time-in-service (TIS) after the effective date of this AD, or 2 years after the effective date of this AD, whichever is earlier.

(i) For all propellers listed by SN in Table 1 or Table 2 of this AD, not involved in a ground strike, use the compliance schedule in the following Table 3 to perform the requirements specified in paragraph (j) or paragraph (k) of this AD as applicable.

Table 3.—Compliance Schedule

If the time-since-overhaul (TSO) for the propeller on the effective date of this AD is—
Then perform the requirements of paragraph (j) or paragraph (k) of this AD within—

(1) 1,500 FH TSO or more.
200 FH TIS after the effective date of this AD, but do not exceed 2 years after the effective date of this AD.

(2) More than 1,000 FH TSO, but fewer than 1,500 FH TIS
350 FH TIS after the effective date of this AD, but do not exceed 2 years after the effective date of this AD.

(3) 1,000 FH TSO or fewer
500 FH TIS after the effective date of this AD, but do not exceed 2 years after the effective date of this AD.

Hartzell Propellers

(j) For Hartzell propellers listed by SN in Table 1 of this AD, do the following:

(1) Disassemble the propeller.

(2) Clean all disassembled propeller parts.

(3) Perform a visual inspection for the following conditions:

(i) Wear or damage such as cracks, corrosion, scratches, or nicks.

(ii) Except for blades installed new at the last CSE maintenance action, examine for:

(A) Bent or damaged pitch change knobs.

(B) Damage in the bore area of the blade shank.

(C) Damage in the blade balance hole.

(iii) Damage that indicates a previous ground strike (if applicable).

(iv) Unacceptable wear or damage in areas where shot peening is required. It is not necessary to strip the paint and corrosion protective coatings from the external surface of the blade. It is also not necessary to perform dimensional measurements on the external surface of the blade unless there is evidence of damage that has occurred since CSE returned the propeller to service.

(v) Confirm that CSE Aviation correctly performed the repairs listed in the manufacturers maintenance manuals. An example of a maintenance manual repair is chamfering of the hub grease fitting hole on Hartzell “Y” shank series propellers.

(4) Perform all Eddy Current inspections applicable.

(5) Repair and replace with serviceable parts, as necessary.

(6) Assemble and test.

(7) Confirm that hubs affected by AD 2001-23-08 are returned to service only on aircraft affected by that AD.

McCauley Propellers

(k) For McCauley propellers listed by SN in Table 2 of this AD, do the following:

(1) Disassemble the propeller.

(2) Clean all disassembled propeller parts.

(3) Perform a visual inspection for the following conditions:

(i) Wear or damage such as cracks, corrosion, scratches or nicks.

(ii) Damage that indicates a previous ground strike (if applicable).

(iii) Unacceptable wear or damage in areas where shot peening is required, paying particular attention to hub internal shot peened surfaces and blade shank peening. It is not necessary to strip the paint and corrosion protective coatings from the external surface of the blade. It is also not necessary to perform dimensional measurements on the external surface of the blade unless there is evidence of damage that has occurred since CSE returned the propeller to service.

(4) Inspect threaded surfaces of threaded blade shanks with a 10X magnifying glass for scratches parallel to retention threads in the thread root of the first four outboard blade threads. If the retention threads are scratched, repair is not allowed.

(5) Confirm that CSE Aviation correctly performed repairs or modifications listed in the manufacturer's maintenance instructions.

(6) Repair and replace with serviceable parts, as necessary.

(7) Assemble and test.

Definitions

(l) For the purposes of this AD, overhauling a propeller is not necessary to comply with the requirements specified in paragraph (j) or paragraph (k) of this AD. If you don't overhaul the propeller, the TSO doesn't change.

Alternative Methods of Compliance (AMOCs)

(m) The Manager, Chicago Aircraft Certification Office, has the authority to approve alternative methods of compliance for this AD if requested using the procedures found in 14 CFR 39.19.

Related Information

(n) The applicable Hartzell Propeller Inc. or McCauley Overhaul Manuals and Service Documents contain information on performing the inspections specified in this AD.

Issued in Burlington, Massachusetts, on June 7, 2005.
