FOR FURTHER INFORMATION CONTACT: Norman Perenson, Aerospace Engineer, New York Aircraft Certification Office, FAA, Engine and Propeller Directorate, 10 Fifth Street, 3rd floor, Valley Stream, NY 11581-1200; telephone (516) 256-7537; fax (516) 568-2716.

SUPPLEMENTARY INFORMATION: DATE: February 11, 2002 2002-04-51

Send to all U.S. owners and operators of Textron Lycoming LTIO-540 and TIO-540 engines. These engines are installed on, but not limited to Piper Navajo (PA 31, PA 31-350, and EMB-820), Piper Saratoga (PA 32-301T, PA 32R-301T, and PA 31-325), Piper Aerostar (PA 60-700P), Piper Malibu Mirage (PA 46-350P), Piper Mojave (PA 31P-350) El Gavilian (EL-1), and Cessna T-206.

This Emergency Airworthiness Directive (AD) is prompted by reports of 14 crankshaft failures in LTIO-540 and TIO-540 engines, rated at 300 HP or higher, that were assembled with crankshafts manufactured from March 1, 1999, through December 31, 1999. This condition, if not corrected, could result in crankshaft failure, which could result in total engine power loss, in-flight engine failure and possible forced landing.

Since an unsafe condition has been identified that is likely to exist or develop on other Textron Lycoming LTIO-540 and TIO-540 engines, rated at 300 HP or higher, that are listed by serial number (SN) in this AD, this AD requires removal of the crankshaft within 10 hours time-in-service (TIS) after receipt of this AD.

This rule is issued under 49 U.S.C. Section 44701 (formerly section 601 of the Federal Aviation Act of 1958) pursuant to the authority delegated to me by the Administrator, and is effective immediately upon receipt of this emergency AD.

Note 1: This AD applies to each engine identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For engines that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (c) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Compliance

Compliance with this AD is required within 10 hours TIS after receipt of this AD, unless already done.

To prevent crankshaft failure, which could result in total engine power loss, in-flight engine failure and possible forced landing, do the following:
