## Abstract

The FAA is superseding Airworthiness Directives (AD) 2017-19- 14 and AD 2014-16-27, which apply to certain Dassault Aviation Model FALCON 900EX airplanes. Those ADs require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and/or airworthiness limitations. Since the FAA issued AD 2017-19-14 and AD 2014-16-27, the FAA determined that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
