Is AD 2021-26-14 a recurring Airworthiness Directive?

Yes — AD 2021-26-14 requires a repetitive inspection every 110 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2021-26-14 apply to?

AD 2021-26-14 applies to Airbus Helicopters — models AS332L2, EC225LP, AS332, EC225. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Airbus Helicopters

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2018-11- 01, which applied to certain Airbus Helicopters Model AS332L2 and EC225LP helicopters. AD 2018-11-01 required installing a cut-out for the left-hand (LH) and right-hand (RH) rail support junction profiles and repetitively inspecting splices, frame 5295, and related equipment for a crack. Since the FAA issued AD 2018-11-01, the manufacturer has developed a modification for in-service helicopters for replacing aluminum splices with steel splices on frame 5295. This AD retains the requirements of AD 2018-11-01 and requires a modification for replacing aluminum splices with steel splices on frame 5295 if cracking is found. This AD also provides terminating action for the repetitive inspections. 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.

Whether AD 2021-26-14 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 2021-26-14 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.
