## Abstract

The FAA is superseding Airworthiness Directives (ADs) 2016-01- 16, 2017-19-03, and 2018-19-05, which applied to Dassault Aviation Model MYSTERE-FALCON 900 airplanes. Those ADs require revising the maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and/or airworthiness limitations. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since AD 2018-19-05 was issued, the FAA has determined that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address the unsafe condition on these products.
