What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model SA341G and SA342J helicopters. This AD was prompted by the determination that a new life limit was necessary for certain tail rotor blades (TRBs). This AD requires replacing certain TRBs, re-identifying certain TRBs, and repairing certain other TRBs, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Part-conditional — 341A335101.01, 341A335130.05, 341A335130.06.

Applies to helicopters equipped with a tail rotor blade (TRB) that is either an affected part as defined in European Union Aviation Safety Agency (EASA) AD 2019-0034, dated February 14, 2019 (EASA AD 2019-0034), or has part number 341A335101.01, 341A335130.05, or 341A335130.06.

Whether AD 2021-08-05 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 2021-08-05 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.
