Airworthiness Directives; Eurocopter France Model SA341G and SA342J Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to Eurocopter France Model SA341G and SA342J helicopters. This action requires inspecting the tail gearbox support tripod (support tripod) for cracks. This amendment is prompted by reports of cracks that were discovered during routine maintenance inspections. The actions specified in this AD are intended to detect cracks at the welds of the tail gearbox support tripod, which could cause failure of one or more of the tripod arms, subsequent separation of the tail gearbox, and loss of control of the helicopter.

Whether AD 98-06-36 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 98-06-36 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.
