Start Preamble

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

The FAA is superseding an existing airworthiness directive (AD) for Lycoming Engines (formerly Textron Lycoming) models 320, 360, and 540 series, “Parallel Valve” reciprocating engines, with certain Engine Components Inc. (ECi) cylinder assemblies, part number (P/N) AEL65102 series “Classic Cast”, installed. That AD currently requires replacing these ECi cylinder assemblies. This AD requires the same actions, but replaces the “Engine Models” Table 1 and “Engines Installed On, But Not Limited To” Table 2 with corrected tables. Also, this AD corrects the casting part number. This AD results from reports of applicability errors found in AD 2005-26-10. We are issuing this AD to prevent loss of engine power due to cracks in the cylinder assemblies and possible engine failure caused by separation of a cylinder head.

DATES:

This AD becomes effective July 11, 2006.

ADDRESSES:

You may examine the AD docket on the Internet at http://dms.dot.gov or in Room PL-401 on the plaza level of the Nassif Building, 400 Seventh Street, SW., Washington, DC.

SUPPLEMENTARY INFORMATION:

The FAA proposed to amend 14 CFR part 39 with a proposed AD. The proposed AD applies to Lycoming Engines models 320, 360, and 540 series, “Parallel Valve” reciprocating engines, with certain ECi cylinder assemblies, P/N AEL65102 series “Classic Cast”, installed. We published the proposed AD in the Federal Register on February 24, 2006 (71 FR 9480). That action proposed to require the same actions as AD 2005-26-10, but would replace the Start Printed Page 32428“Engine Models” Table 1 and “Engines Installed On, But Not Limited To” Table 2 with corrected tables. Also, that action proposed to correct the casting part number.

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 Office 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 street address 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 Change All References to Casting P/N AEL65099

One commenter requests that we change all references to casting P/N AEL65099 to read “casting head markings EC 65099-REV-1” to more accurately describe the actual markings. We agree, and made the reference changes in the AD.

Request To Explain Another Set of Numbers on the Cylinder

The same commenter requests that we explain that the set of numbers appearing on the cylinder below and to the left of the SN, in the form of “12345-67” is not used for determining applicability. We agree, and have added a statement to point this out in the AD.

Update to Related Information

Under paragraph (k), Related Information, we updated the reference to ECi Service Bulletin No. 05-08, Revision 1, dated December 29, 2005, to Revision 2, dated February 28, 2006.

Conclusion

We have carefully reviewed the available data, including the comments 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 7,557 ECi cylinder assemblies are installed on Lycoming engines in the United States. We estimate that it will take about two workhours per engine to perform the aircraft inspections of the cylinder assemblies for applicability, and that the average labor rate is $65 per workhour. From the Lycoming Engines “Removal and Installation Labor Allowance Guidebook”, dated May 2000, the complete cylinder replacement for a four cylinder engine takes 12 hours, while the complete cylinder replacement for a six cylinder engine takes 16 hours. Required parts will cost about $1,000 per cylinder assembly. Based on these figures, we estimate that the total cost of the AD to U.S. operators to be $9,152,140. ECi indicated that they might give operators and repair stations credit for returned cylinder assemblies toward the purchase of new ECi cylinder assemblies.

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.

Unsafe Condition

(d) This AD results from reports of applicability errors found in AD 2005-26-10. We are issuing this AD to prevent loss of engine power due to cracks in the cylinder assemblies and possible engine failure caused by separation of a cylinder head.

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 Not Overhauled or Repaired Since New

(f) If your engine has not been overhauled or had any major repair since new, no further action is required.

Engines Overhauled or Repaired Since New

(g) If your engine was overhauled or repaired since new, do the following:

(1) Determine if ECi cylinder assemblies, P/N AEL65102 series “Classic Cast”, having casting head markings EC 65099-REV-1 and SNs 1 through 9879 (SN may have an “L” prefix for a long reach spark plug) are installed on your engine, as follows:

(i) Inspect the engine log books and maintenance records for reference to the subject ECi cylinder assemblies.

(ii) If the engine log books and maintenance records did not record the P/N and SN of the cylinder assemblies, visually inspect the cylinder assemblies and verify the P/N and SN of the cylinder assemblies.

(2) If the cylinder assemblies are not ECi, P/N AEL65102 series “Classic Cast”, having casting head markings EC 65099-REV-1, no further action is required.

(3) If any cylinder assembly is an ECi P/N AEL65102 series “Classic Cast”, having casting head markings EC 65099-REV-1 and a SN 1 through 9879 (SN may have an “L” prefix for a long reach spark plug), do the following:

(i) If the cylinder assembly has fewer than 800 operating hours-in-service (HIS) on the effective date of this AD, replace the cylinder assembly at no later than 800 operating HIS. No action is required until the operating HIS reaches 800 hours.

(ii) If the cylinder assembly has 800 operating HIS or more on the effective date of this AD, replace the cylinder assembly within 60 operating HIS after the effective date of this AD.

Definition of a Replacement Cylinder Assembly

(h) For the purpose of this AD, a replacement cylinder assembly is defined as follows:

(1) A serviceable cylinder assembly made by Lycoming Engines.

(2) A serviceable FAA-approved, Parts Manufacturer Approval cylinder assembly from another manufacturer.

(3) A serviceable ECi cylinder assembly,P/N AEL65102 series, “Titan”, having casting P/N AEL85099.

(4) A serviceable ECi cylinder assembly, P/N AEL65102 series “Classic Cast”, having casting head markings EC 65099-REV-1, that has a SN 9880 or higher (SN may have an “L” prefix for a long reach spark plug).

Prohibition of Cylinder Assemblies, P/N AEL65102 Series “Classic Cast”, Having Casting Head Markings EC 65099-REV-1 and SNs 1 Through 9879

(i) After the effective date of this AD, do not install any ECi cylinder assembly, P/N AEL65102, having casting head markings EC 65099-REV-1 that has a SN 1 through 9879 (SN may have an “L” prefix for a long reach spark plug), onto any engine.

Alternative Methods of Compliance
