Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model EC225LP, AS332C, AS332L, AS332L1, and AS332L2 helicopters. This AD requires inspecting each TECALEMIT flexible hydraulic hose (hose) installed in the main gearbox (MGB) compartment and replacing the hose if a crack, cut, or other damage exists. This AD was prompted by reports about the loss of in-flight hydraulic pressure on Eurocopter France helicopters. The actions of this AD are intended to prevent loss of the hydraulic system and consequently, loss of helicopter control.

ModelsEC225LP, AS332C, AS332L, AS332L1, AS332L2, EC225, AS332

Applies only to helicopters with a TECALEMIT main gearbox (MGB) hydraulic flexible hose installed.

Whether AD 2016-07-29 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 2016-07-29 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.
