This amendment adopts a new airworthiness directive (AD), applicable to AlliedSignal, Inc. (formerly Textron Lycoming) LTS101 series turboshaft and LTP101 series turboprop engines, that requires identifying, removing, and replacing certain defective power turbine rotors. This amendment is prompted by reports of workmanship deficiencies on certain power turbine rotors that can reduce the published life limit of the disk. The actions specified by this AD are intended to prevent power turbine rotor failure, which could result in loss of engine power.
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.
