Airworthiness Directives; Eurocopter France Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC 155B, EC155B1, SA-365N, SA- 365N1, AS-365N2, AS 365 N3, and SA-366G1 helicopters. This AD requires inspecting the collective pitch lever for correct locking and unlocking conditions. This AD was prompted by two separate reports of inadvertent collective pitch lever locking and unlocking. The actions of this AD are intended to detect an incorrectly adjusted collective pitch lever, which could result in loss of control of the helicopter.

Applies to all listed models except helicopters with modification (MOD) 0767B5 installed.

Whether AD 2013-18-11 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 2013-18-11 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.
