Airworthiness Directives; Eurocopter France (Eurocopter) Model AS332C, L, L1, and L2 Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter model helicopters. This action requires replacing each affected hydraulic pump with an airworthy hydraulic pump. This amendment is prompted by the loss of the proper functioning of a hydraulic pump because of the deterioration of the pump seals and the loss of hydraulic fluid caused by incorrect positioning of the piston liner. The actions specified in this AD are intended to prevent loss of hydraulic power and subsequent loss of control of the helicopter.

Which aircraft AD 2010-20-02 applies to

Applicability depends on the aircraft’s type certificate — check it against the specific tail.

Whether AD 2010-20-02 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 2010-20-02 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.
