A proposal is not in force. If adopted, it becomes an AD, usually with changes. Only the Federal Register edition is official.

Summary

This document proposes the adoption of a new airworthiness directive (AD), applicable to AlliedSignal Engines (formerly Textron Lycoming) LTS101 series turboshaft engines installed on Eurocopter France (formerly Aerospatiale) Model AS-350D and SA-366G1 helicopters. This proposal would require incorporation of design modifications to the power turbine (PT) rotor. This proposal is prompted by reports of PT disk failures after No. 3 bearing failures. The actions specified by the proposed AD are intended to prevent an uncontained engine failure due to a PT disk failure.

The resulting AD
