Airworthiness Directives; Airbus Helicopters (Type Certificate Previously Held by Eurocopter France) (Airbus Helicopters)

What this AD requires

We are superseding airworthiness directive (AD) 2010-11-51 for Eurocopter France (Eurocopter) Model AS350B, BA, B1, B2, C, D, and D1 helicopters and Model AS355E, F, F1, F2, and N helicopters with certain part-numbered tail gearbox (TGB) control levers installed. AD 2010-11- 51 required repetitive visual inspections of the TGB control lever for a crack and replacing a cracked TGB control lever with an airworthy TGB control lever. This new AD retains the requirements of AD 2010-11-51 and also requires inspecting other areas of the TGB control lever not previously inspected and at additional inspection intervals. This AD was prompted by several reports of cracking in a TGB control lever. The actions of this AD are intended to prevent failure of the TGB control lever, loss of tail rotor control, and subsequent loss of control of the helicopter.

Repetitive inspection. Re-inspect every 10 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Which aircraft AD 2014-04729 applies to

Applicability depends on the aircraft’s type certificate — check it against the specific tail.

Whether AD 2014-04729 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

Supersession

Supersedes AD 2010-11-51.

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 2014-04729 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.
