Airworthiness Directives; Airbus Helicopters

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2015-26- 01, which applied to certain Airbus Helicopters Model AS332C1, AS332L1, AS332L2, EC225LP, AS-365N2, AS 365 N3, EC 155B, and EC155B1 helicopters with an energy-absorbing seat. AD 2015-26-01 required inspecting for the presence of labels (placards) that prohibit stowing anything under the seat, and if a label (placard) is missing or not clearly visible to each occupant, installing a label (placard). This AD retains all of the requirements of AD 2015-26-01, and also adds helicopters to the applicability and requires a modification (installing new labels (placards)). This AD was prompted by the determination that additional helicopters are affected by the unsafe condition, and that new labels (placards) are required for all affected helicopters. The FAA is issuing this AD to address the unsafe condition on these products.

Applies to helicopters equipped with at least one energy-absorbing seat listed in figure 1 to paragraph (c) of this AD, except any helicopter that has embodied the applicable Airbus Helicopters modifications on all applicable seat positions listed in figure 2 to paragraph (c) of this AD.

Whether AD 2021-02-01 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 2021-02-01 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.
