Is AD 2000-13-08 a recurring Airworthiness Directive?

Yes — AD 2000-13-08 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2000-13-08 apply to?

AD 2000-13-08 applies to Eurocopter — models EC135. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Eurocopter Deutschland GmbH Model EC 135 Helicopters

What this AD requires

This amendment supersedes an existing airworthiness directive (AD) that applies to Eurocopter Deutschland GmbH (ECD) Model EC 135 helicopters. That AD requires conducting a tail rotor drive shaft vibration survey (survey), installing a Fenestron Shaft Retrofit Kit, inspecting each tail rotor drive shaft bearing (bearing) attaching lock plate for bent-open tabs and broken or missing slippage marks, and visually inspecting each bearing support for cracks. This AD requires conducting the survey and installing the Fenestron Shaft Retrofit Kit. This AD also requires installing double bearing supports and struts, revising the required compliance time for the repetitive inspections of the bearing attach hardware and supports, and removing the requirement to contact the FAA if a lock plate tab is bent open or if slippage marks are broken or missing. This amendment is prompted by continued reports of misaligned or cracked bearing supports and loose bearing attachment bolts. The actions specified by this AD are intended to prevent loss of drive to the tail rotor 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 — L535M3002 882.

Tail rotor drive shaft vibration survey, Fenestron Shaft Retrofit Kit L535M3002 882 installation, double bearing supports installation, and recurring bearing-support crack/hardware inspections, per Eurocopter Deutschland Alert Service Bulletins EC 135-53A-004 and EC 135-53A-005.

Whether AD 2000-13-08 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 2000-13-08 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.
