Airworthiness Directives; Eurocopter France Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Eurocopter France Model EC 155B, EC155B1, SA-366G1, SA-365N, SA-365N1, AS-365N2, and AS 365 N3 helicopters, which requires modifying the fuel tank draining system. This AD is prompted by a closed fuel tank drain that, in the event of a fuel leak, could result in fuel accumulating in an area containing electrical equipment. The actions are intended to prevent accumulation of fuel in an area with electrical equipment or another ignition source, which may lead to a fire.

EC 155B, EC155B1, and SA-366G1 are excluded if modification 365A084485.00 is installed, or if modifications 0753C98 and 0745C96 are both installed. SA-365N, SA-365N1, AS-365N2, and AS 365 N3 are excluded if modifications 0753C98, 0745C96, and (if a sixth fuel tank is installed) 365A081003.00 are installed, or if modification 365A081003.00 and (if a sixth fuel tank is installed) 365A084485.00 are installed.

Whether AD 2013-12-04 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 2013-12-04 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.
