Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to supersede an existing airworthiness directive (AD) that applies to the products listed above. The existing AD currently requires replacing certain crankshafts. Since we issued that AD, Lycoming Engines discovered that the start date of affected engine models in Mandatory Service Bulletin (MSB) No. 569A, is incorrect. This proposed AD would correct that start date. We are proposing this AD to prevent failure of the crankshaft, which will result in total engine power loss, in-flight engine failure, and possible loss of the aircraft.

DATES:

We must receive comments on this proposed AD by September 26, 2011.

ADDRESSES:

You may send comments by any of the following methods:

Comments Invited

We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2006-24785; Directorate Identifier 2006-NE-20-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments.

We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD.

Discussion

On September 20, 2006, we issued AD 2006-20-09, Amendment 39-14778 (71 FR 57407, September 29, 2006), for Lycoming Engines (L)O-360, (L)IO-360, AEIO-360, O-540, IO-540, AEIO-540, (L)TIO-540, IO-580, and IO-720 series reciprocating engines. That AD requires replacing certain crankshafts. That AD resulted from reports of 23 confirmed failures of similar crankshafts in Lycoming Engines 360 and 540 series reciprocating engines. We issued that AD to prevent failure of the crankshaft, which will result in total engine power loss, in-flight engine failure, and possible loss of the aircraft.

Actions Since Existing AD was Issued

Since we issued AD 2006-20-09, Lycoming Engines discovered that the March 1, 1997 start date of affected engine models in Mandatory Service Bulletin (MSB) No. 569A, is incorrect.

Relevant Service Information

We reviewed Lycoming Engines MSB No. 569A, dated April 11, 2006. That MSB describes procedures for replacing crankshafts listed by serial number in that MSB. We also reviewed Lycoming Engines Supplement No. 1 to MSB 569A, dated May 27, 2009. The supplement corrects the start date of affected engine models, to January 1, 1997.

FAA's Determination

We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs.

Proposed AD Requirements

This proposed AD would retain all of the requirements of AD 2006-20-09. This proposed AD would change the start date of affected engine models, from March 1, 1997, to January 1, 1997.

Costs of Compliance

We estimate that this proposed AD would require no additional costs of compliance over those in the original AD, AD 2006-20-09, which are $60,384,000. This proposed AD carries over the original costs of compliance. We estimate that this proposed AD would affect 3,774 engines installed on airplanes of U.S. registry. Because the proposed AD compliance interval coincides with engine overhaul or other engine maintenance, we estimate no additional labor hours will be needed to comply with this proposed AD. Parts would cost about $16,000 per engine. Based on these figures, we estimate the total cost of the proposed AD to be $60,384,000. Our estimate is independent of any possible warranty coverage.

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),

(3) Will not affect intrastate aviation in Alaska, and

(4) 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.

Unsafe Condition

(d) This AD results from Lycoming Engines discovering that the March 1, 1997 start date of affected engine models in Mandatory Service Bulletin (MSB) No. 569A, is incorrect. Lycoming Engines issued Supplement 1 to MSB No. 569A, dated May 27, 2009, which corrected the date of affected engine models, to January 1, 1997. We are issuing this AD to prevent failure of the crankshaft, which will result in total engine power loss, in-flight engine failure, and possible loss of the aircraft.

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.

Engines for Which No Action Is Required

(f) If your engine meets any of the following conditions, and you have not had the crankshaft replaced since meeting the condition, no further action is required:

(1) Engines that are in compliance with Lycoming MSB No. 552 (AD 2002-19-03) or MSB No. 553 (AD 2002-19-03 Table 3 or Table 5); or

(2) Engines that are in compliance with Lycoming MSB No. 566 AD (2005-19-11); or

(3) Engines that are in compliance with Lycoming Supplement No. 1 to MSB No. 566 (AD 2006-06-16); or

(4) Engines that are in compliance with the original issue of Lycoming MSB No. 569, MSB No. 569A, and Supplement 1 to MSB No. 569A.

(5) For engines identified in paragraphs (f), (g), (h), or (i) of this AD, owners or operators may make an entry in the AD status log required by 14 CFR 91.417(a)(2)(v) that this AD required no action for compliance.

(g) If Lycoming Engines manufactured new, rebuilt, overhauled, or repaired your engine, or replaced the crankshaft in your engine before January 1, 1997, and you have not had the crankshaft replaced, no further action is required.

(h) If Table 1, Table 2, Table 3, or Table 4 of Lycoming MSB No. 569A, dated April 11, 2006, lists your engine serial number (S/N), and Table 5 of MSB No. 569A, dated April 11, 2006, does not list your crankshaft S/N, no further action is required.

(i) For engine model TIO-540-U2A, S/N L-4641-61A, no action is required.

Engines for Which Action Is Required

(j) If Table 1, Table 2, Table 3, or Table 4 of Lycoming MSB No. 569A, dated April 11, 2006, lists your engine S/N, and Table 5 of MSB No. 569A, dated April 11, 2006, lists your crankshaft S/N, replace the affected crankshaft with a crankshaft that is not listed in Table 5 of MSB No. 569A at the earliest of the following:

(1) The time of the next engine overhaul as specified in Lycoming Engines Service Instruction No. 1009AS, dated May 25, 2006; or

(2) The next separation of the crankcase, or

(3) No later than 12 years from the time the crankshaft first entered service or was last overhauled, whichever is later.

(k) If Table 1, Table 2, Table 3, or Table 4 of Lycoming MSB No. 569A, dated April 11, 2006, does not list your engine S/N, and Table 5 of MSB No. 569A does list your crankshaft S/N (an affected crankshaft was installed as a replacement), replace the affected crankshaft with a crankshaft that is not listed in Table 5 of MSB No. 569A at the earliest of the following:

(1) The time of the next engine overhaul as specified in Lycoming Engines Service Instruction No. 1009AS, dated May 25, 2006; or

(2) The next separation of the crankcase, or

(3) No later than 12 years from the time the crankshaft first entered service or was last overhauled, whichever is later.

Prohibition Against Installing Certain Crankshafts

(l) After the effective date of this AD, do not install any crankshaft that has a S/N listed in Table 5 of Lycoming MSB No. 569A, dated April 11, 2006, into any engine.

Alternative Methods of Compliance (AMOC)

(m) The Manager, New York Aircraft Certification Office, has the authority to approve AMOCs for this AD if requested using the procedures found in 14 CFR 39.19. AMOCs approved for AD 2006-20-09 are approved as AMOCs for this AD.
