Airworthiness Directives; Airbus Helicopters

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332C1 and AS332L1 helicopters. This AD was prompted by a report that the affected helicopters use the same "flight/ground" logic signal, instead of independent redundant signals. This AD requires amending the emergency procedures of the existing rotorcraft flight manual (RFM) for your helicopter, a wiring modification of the "flight/ground" logic signal source of the attitude and heading reference system (AHRS) 1, and then removal of the amendment to the existing RFM for your helicopter. The FAA is issuing this AD to address the unsafe condition on these products.

Which aircraft AD 2020-22-13 applies to

MakesAirbus Helicopters
ModelsAS332C1, AS332L1, AS332

Applies only to helicopters (all manufacturer serial numbers) equipped with an Advanced Helicopter Cockpit & Avionics System (AHCAS), except those with Airbus Helicopters modification 0728576 embodied in production.

Whether AD 2020-22-13 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 2020-22-13 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.
