Is AD 98-10-04 a recurring Airworthiness Directive?

Yes — AD 98-10-04 requires a repetitive inspection every 250 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 98-10-04 apply to?

AD 98-10-04 applies to Eurocopter France — models SA-365N1, AS-365N2, SA-366G1, SA-365, AS-365, SA-366. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Eurocopter France Model SA-365N1, AS- 365N2, and SA-366G1 Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to Eurocopter France (Eurocopter) Model SA-365N1, AS-365N2, and SA-366G1 helicopters, that requires initial and repetitive inspections of the tail rotor blade Kevlar tie-bar (Kevlar tie-bar) for cracks or delaminations. This amendment is prompted by a report of delamination of a Kevlar tie-bar. The actions specified by this AD are intended to detect cracks that could lead to delamination of the Kevlar tie-bar, loss of tail rotor control, and subsequent loss of control of the helicopter.

Repetitive inspection. Re-inspect every 250 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Whether AD 98-10-04 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 98-10-04 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.
