Airworthiness Directives; Eurocopter France Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS350BA helicopters with certain AERAZUR emergency flotation gear container assemblies installed. This AD requires replacing each affected emergency flotation gear container assembly (container assembly) at specified time limits based on the date of manufacture. This AD was prompted because container assemblies with an intended operating limitation of 10 years may not have been replaced because the limit is no longer recorded in the Maintenance Program. The actions of this AD are intended to prevent failure of the emergency container assembly because of age and subsequent damage to the helicopter and injury to the occupants after an emergency water landing.

ModelsAS350BA, AS350

Part-conditional — 158170, 158210-1, 158171, 158215-1.

Applies only when AERAZUR left-hand emergency flotation gear container assembly P/N 158170 or 158210-1, or right-hand container assembly P/N 158171 or 158215-1, is installed.

Whether AD 2012-26-07 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 2012-26-07 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.
