Airworthiness Directives; Eurocopter France Model SA 330J Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to Eurocopter France (Eurocopter) Model SA 330J helicopters. This action requires the visual inspection and, if any crack is found, replacement of the affected main rotor head sleeve. This amendment is prompted by the discovery of a crack through the thickness of a lower lug of a blade sleeve. The actions specified by the proposed AD are intended to prevent failure of a main rotor head sleeve that could result in the loss of a main rotor blade and subsequent loss of control of the helicopter.

Which aircraft AD 99-07-07 applies to

MakesEurocopter

Part-conditional — 330A31.1376.00 to .05, 330A31.1376.12 to .17.

Main rotor head sleeve (lug) crack inspection AD to prevent loss of a main rotor blade; sleeve P/N 330A31.1376.00 through .05 or 330A31.1376.12 through .17; actions per Eurocopter France Service Bulletin 05.80R1, dated February 14, 1995. The P/N prefix 330A31 is consistent with SA330-family parts numbering, but the specific model is not stated in the extracted text; cross-referenced to DGAC (France) AD 91-021-064(B)R1.

Whether AD 99-07-07 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 99-07-07 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.
