Airworthiness Directives; Dassault Aviation Airplanes

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2019-23- 03, which applied to certain Dassault Aviation Model FALCON 900EX airplanes. AD 2019-23-03 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and/or airworthiness limitations. This AD continues to require those maintenance or inspection program revisions, and also requires revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive airworthiness limitations; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address the unsafe condition on these products.

Which aircraft AD 2020-21-20 applies to

MakesDassault Aviation
ModelsFALCON 900EX, FALCON
Serial-conditional — narrows to serials 97–97, 120–?.

Applies only to aircraft with an original airworthiness certificate or original export certificate of airworthiness issued on or before October 2, 2019.

Whether AD 2020-21-20 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2020-21-20 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.
