Airworthiness Directives; Airbus Helicopters

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS350B2, AS350B3, EC120B, and EC130B4 helicopters. This AD was prompted by a short-circuit due to foreign object debris (FOD) or dust inside the lighting and ancillaries control unit (LACU). This AD requires repetitively cleaning and inspecting the affected LACU for FOD. Depending on the configuration of the helicopter, this AD also requires modifying the emergency floatation system (EFS) activation switches and revising the existing rotorcraft flight manual (RFM) for the helicopter, which would constitute a terminating action for the repetitive cleaning and inspection requirements. Additionally, this AD prohibits installing an affected LACU on any helicopter unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.

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.

Whether AD 2026-14-02 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 2026-14-02 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.
