What this AD requires

We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS 365 N3, EC 155B, and EC155B1 helicopters with certain external life rafts. This AD requires installing a sheath kit on the left-hand and right-hand raft deployment control systems. This AD is prompted by a report that the life raft deployment control could not be adjusted due to problems with the life raft deployment linkage. This unsafe condition, if not corrected, could result in failure of the external life raft to deploy and prevent evacuation of passengers during an emergency.

Whether AD 2016-05-10 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 2016-05-10 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.
