Airworthiness Directives; Turbomeca S.A. Arriel 2B Turboshaft Engines

What this AD requires

The FAA is revising an existing airworthiness directive (AD) for Turbomeca S.A. Arriel 2B turboshaft engines with Modification TU62A incorporated. That AD currently requires initial and repetitive inspections, cleaning, lubrication, and checks for proper operation of the HMU acceleration controller axle. This AD requires the same actions, but removes engines incorporating TU132 from the applicability and adds an optional terminating action for the repetitive actions required in AD 2005-13-25. This AD results from the engine manufacturer releasing a service bulletin to introduce modification TU132. We are issuing this AD to prevent loss of control of engine fuel flow in manual control mode or mixed control mode, which can lead to engine overspeed, and in-flight engine shutdown resulting in a forced autorotation landing or accident.

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.

Which aircraft AD E7-7115 applies to

MakesTurbomeca S.A.
ModelsArriel 2B, Arriel

Applies to engines with Modification TU62A incorporated but without Modification TU132. Installed on, but not limited to, Eurocopter AS350B3 helicopters.

Whether AD E7-7115 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 E7-7115 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.
