Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) Helicopters

What this AD requires

We are superseding airworthiness directive (AD) 2010-21-07 for Eurocopter France (now Airbus Helicopters) Model AS350B3 and EC130B4 helicopters. AD 2010-21-07 required inspecting the pilot's and co- pilot's throttle twist for proper operation of the contactors. This new AD retains the requirements of AD 2010-21-07, includes additional inspection procedures, and revises the inspection interval. These actions are intended to address the unsafe condition on these products.

Which aircraft AD 2016-25-19 applies to

MakesAirbus Helicopters

ModelsAS350B3, EC130B4, AS350, EC130

Applies only to helicopters with the Arriel 2B1 engine equipped with two-channel FADEC and with new twist grip modification (MOD) 073254 installed (AS350B3) or MOD 073773 installed (EC130B4).

Whether AD 2016-25-19 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 2016-25-19 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.
