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 AlliedSignal Inc. LTS101 series turboshaft and LTP101 series turboprop engines, that requires replacement of cast material axial compressor rotors with wrought material axial compressor rotors that have improved fatigue characteristics and material properties. This amendment is prompted by 36 reports of axial compressor blade failures on cast rotors. The actions specified by this AD are intended to prevent engine power loss and 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.
