More Suspect Lycoming Cranks

[Sport_AV]

If your engine is on the list in the MSB supplement, Lycoming wants you to phone them (570-323-6181) or fax them (570-327-7160) to arrange its return. If your engine was rebuilt or had the crankshaft replaced after March 1, 1999, you need to hunt down the repair records and find the crankshaft serial number to compare to the list contained in the MSB supplement. If your number comes up, you need to call or fax, too. Lycoming will cover a "reasonable" amount of labor for the removal and reinstallation of the engine. At the factory, it will be disassembled, inspected and the cranks and bearings replaced.

Lycoming is casting its recall net a little wider for engines with potentially faulty crankshafts and the FAA is reinforcing that with yet another proposed AD. Since 2002, Lycoming has replaced hundreds of cranks containing suspected metallurgical faults and now nearly 400 more have been added to the list. In a Nov. 30 supplement (check there to see if your engine is affected) to a mandatory service bulletin issued last July, Lycoming said a single failure (no accident involved) prompted the expanded recall. The Notice of Proposed Rulemaking issued by the FAA on Jan. 6 duplicates the company's call for the affected engines to be repaired within 50 hours or six months, whichever comes first. The MSB supplement and NPRM affect (L)O-360, (L)IO-360, and AEIO-360 models.
