Reminiscent of last year?s Teledyne Continental crankshaft
problems, Textron Lycoming recently released Service Bulletin (SB)
549 highlighting a ?potential metallurgical condition? on crankshafts
installed in four-cylinder 360-series engines or shipped as spare
parts. The suspect crankshafts were shipped from the Lycoming
factory May 1, 1997, through April 30, 2000, and are listed by serial
number in the SB. Lycoming requires that affected airplanes
undergo nondestructive testing at one of several Lycoming-certified
facilities listed in the SB, and will extend warranty coverage for cost
of the required inspections through October 31 of this year.

An aircraft piston engine is a high strung beast if there ever was one. The least little
defect can be disastrous.
