What this AD requires

We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a report indicating that, under certain operational takeoff conditions, the available thrust in relation with the N1 indication is less than a certified value, which could affect the safety margins with an engine failure during takeoff. This AD requires modifying each engine by updating the electronic engine control (EEC) software and adjusting the engine N1 trim value, and revising the airplane flight manual (AFM). We are issuing this AD to address the unsafe condition on these products.

Whether AD 2017-17401 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 2017-17401 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.
