Airworthiness Directives; Turbomeca S.A. Turboshaft Engines

What this AD requires

We are adopting a new airworthiness directive (AD) for Turbomeca S.A. Arriel 1D and 1D1 turboshaft engines with a pre- modification (mod) TU357 gas generator module (M03), installed. This AD requires removing the pre-modification (mod) TU357 gas generator module (M03) and replacing with a part eligible for installation. This AD was prompted by reports of divergent rubbing between the piston shaft small diameter labyrinth and the rear bearing support. We are issuing this AD to prevent failure of the labyrinth seal and engine, in-flight shutdown, and loss of control of the helicopter.

ModelsArriel 1D, Arriel 1D1, Arriel

Applies only to engines with a pre-modification (mod) TU357 gas generator module (M03) installed.

Whether AD 2016-11-09 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 compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 2016-11-09 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.
