What this AD requires

This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) model helicopters that requires inspecting certain main rotor blades for disbonds, which may be indicated by cracking, and repairing or replacing each main rotor blade (MRB) as necessary. This amendment is prompted by the discovery of disbonded leading edge protective strips. The actions specified by this AD are intended to detect disbonding between the stainless steel protective strip and the MRB skin, which could cause loss of the protective strip, an out-of-balance condition, and subsequent loss of control of the helicopter.

ModelsAS332

Applies to Eurocopter AS332 helicopters with main rotor blades (MRB) per Groups 1 and 2 of the AD's Applicability section (not included in this excerpt). Repetitive inspection interval for disbonding of the stainless steel protective strip depends on whether the installed MRB serial number appears on a specific list (Group 1 MRBs with listed serial numbers: 100 hrs TIS then every 100 hrs; Group 1 MRBs not on list: 100 hrs then every 250 hrs; Group 2 MRBs with >=400 hrs TIS: 100 hrs then every 500 hrs; Group 2 MRBs <400 hrs TIS: before 500 hrs then every 500 hrs), per Eurocopter AS 332 Service Bulletin No. 05.00.22.

Whether AD 2003-21-08 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 2003-21-08 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.
