Airworthiness Directives; Eurocopter France Model EC 155B and EC155B1 Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC 155B and EC155B1 helicopters. This AD results from mandatory continuing airworthiness information (MCAI) issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI states that "the Airworthiness Directive (AD) is prompted by the discovery of a short circuit evidence in hoist connector "24 Delta" even though the hoist was removed from the rotorcraft. The short circuit generated sufficient heat to ignite the paint on the cooler support cowling near the hoist cut-off connector "24 Delta." This condition, if not corrected, could result in a fire in this area which could propagate to surrounding zones." This AD requires actions that are intended to address this unsafe condition.

Which aircraft AD 2009-06-01 applies to

ModelsEC155B, EC155B1, EC155
Serial-conditional — narrows to serials ?–6763.
Part-conditionalOP 45C07.

Applies to helicopters with S/N less than 6763 and with optional equipment kit OP 45C07 (helicopter provision kit -- electrical and structural mount modifications supporting hoist installation/operation) installed; installation verified via aircraft documentation or physical inspection for the 24 Delta hoist electrical connector per Eurocopter ASB No. 25A085 dated June 1, 2007.

Whether AD 2009-06-01 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2009-06-01 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.
