Airworthiness Directives; Eurocopter France Model AS332L2 Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) for Eurocopter France Model AS332L2 helicopters. This AD requires, at specified time intervals, visually inspecting the main rotor blade sleeve yoke (sleeve) for cracks, corrosion, fretting, or bonding separation; the bearing surface of the metal bushing (bushing) for fretting or cracks; and the sleeve-to-damper attachment bolt (bolt) for corrosion and deterioration of the fluorimid varnish coating. Replacing any cracked or nonairworthy sleeve, bushing, or bolt is also required before further flight. This AD is prompted by the discovery of extensive deterioration of the fluorimid varnish coating on the bolt; cracks in the bushing; and fretting and corrosion of the sleeve. The actions specified in this AD are intended to detect corrosion and cracks in the yoke, which could result in separation of the blade damper assembly and subsequent loss of control of the helicopter.

Cross-reference boilerplate only; model list precedes excerpt and was not captured. Requires inspection of the main rotor blade sleeve-to-blade-damper attachment bolt and sleeve yoke per Eurocopter Service Bulletin No. 05.00.53, Revision 1, dated July 6, 1999.

Whether AD 2001-12-16 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 2001-12-16 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.
