Airworthiness Directives; Eurocopter France Model AS332 C, L, and L1 Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS332 C, L, and L1 helicopters. This action requires revising the Rotorcraft Flight Manual (RFM) Limitations section if certain fuel control units are installed. This AD is prompted by the discovery of an anomaly in certain fuel control units that may lead to inadequate fuel flow in single-engine flight. This condition, if not corrected, could result in failure of the engine to develop the maximum 2\1/2\ minute one engine inoperative (OEI) power, reduced helicopter performance, and subsequent loss of control of the helicopter during OEI operation.

Whether AD 2003-11-21 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 2003-11-21 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.
