Is AD 2021-13-19 a recurring Airworthiness Directive?

Yes — AD 2021-13-19 requires a repetitive inspection every 110 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2021-13-19 apply to?

AD 2021-13-19 applies to Airbus Helicopters — models SA-365N, SA-365N1, AS-365N2, AS-365N3, SA-365, AS-365. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2014-11-02 for Airbus Helicopters Model SA-365N, SA-365N1, AS-365N2, and AS 365 N3 helicopters. AD 2014-11-02 required repetitively inspecting frame number (No.) 9 for a crack. This AD was prompted by Airbus Helicopters developing a modification that provides an optional terminating action for the repetitive inspections required by AD 2014-11-02. This AD retains the requirements of AD 2014-11-02, provides an optional terminating action for the repetitive inspections, and reduces the applicability by excluding certain post-modified helicopters. The FAA is issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect every 110 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Source applicability text was garbled/interleaved with unrelated regulatory boilerplate (Costs of Compliance, Authority, etc.). Per the codified AD text (2021-13-19) at the end of the document, this AD applies to Airbus Helicopters Model SA-365N, SA-365N1, AS-365N2, and AS 365 N3 helicopters, certificated in any category, EXCEPT those with Eurocopter MOD 53C17 or MOD 53D02, or Airbus Helicopters MOD 07 53D21 or MOD 07 53D22, installed.

Whether AD 2021-13-19 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 2021-13-19 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.
