Summary

The FAA is adopting 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 AD requires inspecting the propeller blades and other critical propeller parts for wear and mechanical damage. This AD results from findings that CSE Aviation failed to perform some 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.

Action Required

Final rule.

Effective Date

Unsafe Condition

(d) This AD results from findings that CSE Aviation failed to perform some specific inspections and repairs. We are issuing this AD to detect potentially 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:

(1) Overhauling a propeller is not necessary to comply with the requirements specified in paragraph (j) or
paragraph (k) of this AD. If you do not overhaul the propeller, the TSO does not change.

(2) Unacceptable wear is wear or damage that can penetrate the shotpeen compressive layer.

Alternative Methods of Compliance

(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.

Supplementary Information

The FAA proposed to amend 14 CFR part 39 with a proposed AD. The proposed AD applies to 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. We published the proposed AD in the Federal Register on June 15, 2005 (70 FR 34714). That action proposed to require inspecting the propeller blades and other critical propeller parts for wear and mechanical damage.

Examining the AD Docket

You may examine the docket that contains the AD, any comments received, and any final disposition in person at the Docket Management Facility Docket Offices between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Office (telephone (800) 647-5227) is located on the plaza level of the Department of Transportation Nassif Building at the streetaddress stated in ADDRESSES. Comments will be available in the AD docket shortly after the DMS receives them.

Comments

We provided the public the opportunity to participate in the development of this AD. We have considered the comments received.

Request To Clarify Reason for the AD

CSE Aviation requests that we clarify the statement "This (proposed) AD results from findings that CSE Aviation failed to perform specific inspections and repairs'', to read "This (proposed) AD results from findings that CSE Aviation failed to perform some specific inspections and repairs''. The commenter states that adding this word more clearly defines the conditions existing in the field. We agree and added the word "some'' in this sentence of the AD.

Request To Clarify the Discussion

CSE Aviation requests that we clarify the Discussion paragraph in the proposed AD to state the following: "The investigators believe the discrepancies date from about 1998 until November 2003 whenCSE Aviation stopped updating their internal procedures to reflect the latest version of the manufacturers' maintenance manuals. The audit also showed that CSE Aviation did not perform some specific inspections required by the maintenance manual. CSE Aviation conducted an internal investigation and confirmed that they did not perform some inspections and rework procedures such as:'' We disagree the discussion paragraph needs change. We find it adequate as drafted. We did not change the AD.

Requests To Clarify Costs of Compliance

CSE Aviation requests that we clarify the Costs of Compliance paragraph by specifying that about 49 affected Hartzell propellers and about 24 affected McCauley propellers are installed on U.S.-registered airplanes. We agree. We changed the Costs of Compliance paragraph in the AD to reflect that about 49 affected Hartzell propellers and 24 affected McCauley propellers are installed on U.S.-registered airplanes.

CSE Aviation also suggests that ourestimate for part cost replacement of $2,350 per propeller, is too high. They suggest a part cost per propeller of $200 per propeller, and suggest that our estimate might lead to other repair facilities replacing parts that are airworthy. They also suggest that the actual total cost for U.S.- registered installations is about $62,050, with a total worldwide cost of about $437,750. We do not agree. The cost numbers provided by CSE Aviation do not include a proper range for defective parts, or include improper repairs that might be found during the inspections. We did not change the AD.

Request To Clarify the Unsafe Condition Statement

CSE Aviation requests that we clarify the unsafe condition statement to state that we are issuing this AD to detect potentially unsafe conditions that could result in a propeller blade separating from the hub and loss of control of the airplane. We agree and added the word "potentially'' in this sentence of the AD.

Request To Change ComplianceParagraph (f)

CSE Aviation requests that we change the words " FAA-approved'' with "appropriately approved'' in compliance paragraph (f), since the affected propeller population is worldwide. We do not agree. Our authority to mandate airworthiness actions is limited to FAA-approved repair facilities and operators, and not foreign country-approved facilities and operators.

Conclusion

We have carefully reviewed the available data, including the comment[s] 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.

Costs of Compliance

We estimate that about 49 Hartzell Propeller Inc. HC series propellers and about 24 McCauley Propeller Systems controllable propellers of the affected design installed on airplanes of U.S. registry will be affected by this AD. We also estimate that it will 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 will cost about $2,350 per propeller. Based on these figures, we estimate the total cost of the 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 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 summary of the costs to comply with this AD and placed it in the AD Docket. You may get a copy of this summary at the address listed under ADDRESSES.
