Airworthiness Directives; Dassault Aviation Airplanes

FAA / Federal Register · 2019-26676

The FAA is adopting a new airworthiness directive (AD) for all Dassault Aviation Model MYSTERE FALCON 50, MYSTERE FALCON 900, and FALCON 900EX airplanes; and Model FALCON 2000 and FALCON 2000EX airplanes. This AD was prompted by a report that the Dassault maintenance planning document (MPD) of the related Dassault aircraft maintenance manual (AMM) states that the "combined service/storage life" of the fire extinguisher percussion cartridges is longer than it should be, and could have a safety impact in case of fire. This AD requires replacing the fire extinguisher percussion cartridges with serviceable parts. The FAA is issuing this AD to address the unsafe condition on these products.
