## Abstract

The FAA is superseding Airworthiness Directive (AD) 2020-26- 07, which applied to all Dassault Aviation Model MYSTERE-FALCON 900 airplanes. AD 2020-26-07 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by a determination that a new airworthiness limitation is necessary. This AD continues to require the actions in AD 2020-26-07, and also requires revising the existing maintenance or inspection program, as applicable, to incorporate a new airworthiness limitation; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
