Airworthiness Directives; Airbus Helicopters (Type Certificate Previously Held by Eurocopter France) Helicopters

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2003-25-01 which applied to certain Eurocopter France (now Airbus Helicopters) Models AS332C, AS332C1, AS332L, AS332L1, AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, and AS355N helicopters. AD 2003-25-01 required modifying and re-identifying the hoist operator control unit and replacing certain fuses. This AD was prompted by the identification of multiple errors in the applicable service information for the AS350-series and AS355-series helicopters and of other needed changes. This AD retains certain requirements of AD 2003-25-01, revises the applicability, and requires using corrected service information. This AD also requires reporting certain information and prohibits the installation of an affected hoist until the required actions are accomplished. The FAA is issuing this AD to address the unsafe condition on these products.

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 2021-15020 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.
