Airworthiness Directives; Eurocopter France Model SA-366G1 Helicopters

What this AD requires

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

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

Part-conditional — 365A12-0020-03.

Specific model not stated in the provided applicability excerpt. Requires inspecting tail rotor blade Kevlar tie-bar for delamination at 10-hr TIS initial (blade P/N 365A12-0020-03 exempt) and 250-hr TIS recurring intervals per Eurocopter France Telex SB 05.19 (Aug 19, 1992) and SB 05.20 Rev 3 (Nov 14, 1996); delaminated blades replaced before further flight.

Whether AD 98-06-35 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 98-06-35 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.
