Airworthiness Directives; Leonardo S.p.a. Helicopters

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AW169 helicopters. This AD was prompted by false simultaneous in-flight disengagement of automatic flight control system (AFCS) channels 1 and 2. This AD requires temporarily revising the existing Rotorcraft Flight Manual (RFM) for your helicopter. This AD also requires installing an AFCS software upgrade and concurrently removing that RFM revision. The FAA is issuing this AD to address the unsafe condition on these products.

ModelsAW169

Part-conditional — 6F2210AS0102.

Applies to helicopters with automatic flight control system (AFCS) software part number 6F2210AS0102 or previous versions installed.

Whether AD 2021-10-01 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 2021-10-01 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.
