Is AD 2000-10-10 a recurring Airworthiness Directive?

Yes — AD 2000-10-10 requires a repetitive inspection every 550 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2000-10-10 apply to?

AD 2000-10-10 applies to Eurocopter — models AS-350B, AS-350BA, AS-350B1, AS-350B2, AS-350D, AS-355E, AS-355F, AS-355F1. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Eurocopter France Model AS-350B, BA, B1, B2, and D, and Model AS-355E, F, F1, F2, and N Helicopters

What this AD requires

This amendment supersedes an existing airworthiness directive (AD) that applies to Eurocopter France Model AS-350B, BA, B1, B2, and D, and Model AS-355E, F, F1, F2, and N helicopters and requires inspecting the main gearbox suspension bi-directional cross-beam (cross-beam) for cracks, and replacing the cross-beam if a crack is found. This amendment requires the same inspections as the existing AD, but adds the time intervals for performing repetitive dye-penetrant inspections on cross-beams with 5,000 or more hours time-in-service (TIS). This amendment is prompted by the discovery that time intervals for performing the required dye-penetrant inspections are not included in the existing AD. The actions specified by this AD are intended to prevent failure of the cross-beam that could lead to rotation of the main gearbox, resulting in severe vibrations and a subsequent forced landing.

Repetitive inspection. Re-inspect every 550 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Modification per Eurocopter SB 63.00.07 (Model AS-350B, BA, B1, B2, D) or SB 63.00.13 (Model AS-355E, F, F1, F2, N), both dated Apr 7, 1997, is terminating action.

Whether AD 2000-10-10 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.

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.
