Airworthiness Directives; Airbus Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS-365N2 and AS 365 N3 helicopters with a lower strobe light installed. This AD requires installing a cable mount, inspecting the lower strobe light wiring harness, and re-routing the wiring harness. This AD was prompted by reports of interference between the lower strobe light wiring harness and the helicopter structure. The actions of this AD are intended to prevent an unsafe condition on these helicopters.

ModelsAS-365N2, AS 365 N3, AS-365

Applies only to helicopters with a lower strobe light installed.

Whether AD 2018-18-11 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 2018-18-11 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.
