Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Airbus Helicopters (previously Eurocopter France) Model AS365N3, EC155B, and EC155B1 helicopters with an external life raft in the footsteps with certain part-numbered junction units. This AD requires inspecting the junction units of the external life raft deployment system for corrosion, removing any corrosion, and performing certain measurements to determine whether the junction unit must be replaced. This AD is prompted by failure of a life raft deployment test and corrosion damage inside the left-hand junction unit. These actions are intended to prevent failure of an external life raft to deploy preventing evacuation of passengers during an emergency.

Part-conditional — 200197, 200188, 704A341302.48, 704A341302.30.

Applies only when an external life raft in the footstep is installed with a junction unit, manufacturer P/N 200197 or 200188 (Airbus Helicopters P/N 704A341302.48 or 704A341302.30).

Whether AD 2015-10-05 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 2015-10-05 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.
