Honeywell International Inc. Engines
This AD applies to Honeywell International Inc. TPE331-14A, TPE331-14B, TPE331-14F, TPE331-15AW.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain AlliedSignal Inc. (formerly Garrett Engine Division) TPE331 series turboprop engines, that establishes cyclic retirement lives for certain compressor components. This amendment is prompted by manufacturer's engine testing and analysis that indicate that if these compressor components continue in service without an established retirement life, accumulative cyclic effects may result in a fatigue failure. The actions specified by this AD are intended to prevent fatigue failure of engine compressor components and an inflight engine shutdown.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
