Full official abstract

This amendment adopts a new airworthiness directive (AD), applicable to AlliedSignal Inc. (formerly Textron Lycoming) LTS 101 series turboshaft and LTP 101 series turboprop engines, that requires removal from service of suspect disks for a one-time inspection of the disk tenon area of the gas generator turbine disk. This amendment is prompted by a report of a gas generator turbine disk tenon failure. The actions specified by this AD are intended to prevent total loss of engine power, inflight engine shutdown, and possible damage to the aircraft.
