Is AD 2010-06-03 a recurring Airworthiness Directive?

No — AD 2010-06-03 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2010-06-03 apply to?

AD 2010-06-03 applies to Eurocopter — models AS355E, AS355F, AS355F1, AS355F2, AS355N, AS355. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Eurocopter France Model AS355E, AS355F, AS355F1, AS355F2, and AS355N Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS355E, AS355F, AS355F1, AS355F2, and AS355N helicopters. This AD results from a mandatory continuing airworthiness information (MCAI) AD issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI AD states that a metallurgical non-conformity was discovered on a flange of the forward shaft section of the tail rotor drive shaft (drive shaft). The MCAI AD also states that stress analysis has shown that this non-conformity can significantly reduce the strength of the drive shaft and thereby its service life. The AD actions are intended to remove non-conforming drive shafts from service and prevent failure of the drive shaft and subsequent loss of control of the helicopter.

ModelsAS355E, AS355F, AS355F1, AS355F2, AS355N, AS355

Serial-conditional — narrows to serials M858–M873.

Part-conditional — 355A34-1090-00.

Applies only to helicopters with tail rotor drive shaft forward shaft section, P/N 355A34-1090-00, serial numbers 858 through 873 (inclusive) bearing prefix 'M', installed. Does not apply to helicopters manufactured after January 1, 2005.

Whether AD 2010-06-03 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 2010-06-03 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.
