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

What this AD requires

This amendment adopts a new airworthiness directive (AD) for Eurocopter France (ECF) Model AS332C, L, and L1 helicopters. This AD requires inspecting the horizontal stabilizer spar tube (spar tube) for corrosion, hardness, cracks, and scratches, and if necessary, replacing any unairworthy spar tube and bushing with an airworthy spar tube and bushing. This amendment is prompted by the loss of a horizontal stabilizer in flight due to a spar tube failure. The actions specified by this AD are intended to prevent failure of the spar tube, separation of the horizontal stabilizer and impact with the main or tail rotor, and subsequent loss of control of the helicopter.

Part-conditional — 330A13-2024-31.

Requires recurring hardness/scratch/corrosion/crack inspections of the horizontal stabilizer spar tube and composite bushing P/N 330A13-2024-31 per Eurocopter France SB 01.00.57 Rev.1, with intervals keyed to accumulated hours/calendar time since bushing replacement. Specific helicopter model designation not present in retrieved text segment (lead-in applicability paragraph not captured).

Whether AD 2000-20-17 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 2000-20-17 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.
