Airworthiness Directives; Eurocopter France Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC225LP helicopters. This AD requires inspecting the swashplates for corrosion or a crack, and making the appropriate repairs or replacement of parts. This AD was prompted by the discovery of corrosion on the swashplates when the main rotor hub (MRH) assemblies were reconditioned. The actions of this AD are intended to detect corrosion or a crack in the swashplates, which could lead to failure of the swashplates and subsequent loss of helicopter control.

Applies only to helicopters with the specified main rotor hub assembly (rotating swashplate and stationary swashplate) installed.

Whether AD 2013-31447 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 2013-31447 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.
