Airworthiness Directives; AlliedSignal, Inc. LTS101 Series Turboshaft Engines Installed on Eurocopter France Model AS-350D and SA- 366G1 Helicopters

What this AD requires

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

Whether AD 96-06-10 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 96-06-10 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
