## Abstract

The FAA is superseding Airworthiness Directive (AD) 2023-04- 16, which applied to certain Dassault Aviation Model FALCON 900EX airplanes. AD 2023-04-16 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-04- 16, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require the actions in AD 2023-04-16, and also requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, 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.
