Airworthiness Directives; Eurocopter France (ECF) Model EC225LP Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for the specified ECF Model EC225LP helicopters. This AD results from a mandatory continuing airworthiness information (MCAI) AD issued by the aviation authority of the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI AD states there have been a "few" reports of cracks and failure of the main rotor hub (MRH) cone restrainer support lugs at their attachment points on the reinforcement ring where the dome fairing is secured. Also, cracks on the dome fairing support have been reported. Failure of the cone restrainer support or the dome fairing support attachment lugs may lead to loss of the dome fairing, damage to the rotor blades, and subsequent loss of control of the helicopter.

Excludes helicopters modified with MOD 0743718.

Whether AD 2010-15-04 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 2010-15-04 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.
