Is AD 2021-28340 a recurring Airworthiness Directive?

Yes — AD 2021-28340 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2021-28340 apply to?

AD 2021-28340 applies to Airbus Helicopters — models EC130T2, EC130. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

The FAA is superseding airworthiness directive (AD) 2021-24- 06, which applied to certain Airbus Helicopters Model EC130T2 helicopters. AD 2021-24-06 required repetitive visual inspections of the rivets on the rear transmission shaft bearing support and of the local structure for cracking and missing, loose, or sheared rivets and accomplishment of applicable corrective actions. This AD retains those requirements and adds repetitive visual inspections of the rivet heads on the left-hand and right-hand sides of the rear transmission shaft bearing support, revises a corrective action, and adds a reporting requirement, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also revises the special flight permit limitation from AD 2021-24-06. This AD was prompted by an additional report of loose rivet heads on the outside face of the tail boom corner support. The FAA is issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Applicability as identified in European Union Aviation Safety Agency (EASA) Emergency AD 2021-0283-E, dated December 17, 2021 (EASA AD 2021-0283-E).

Whether AD 2021-28340 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 2021-28340 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.
