Airworthiness Directives; Dassault Aviation Airplanes

FAA / Federal Register · 2019-26704

The FAA is adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 900EX and Model FALCON 2000EX airplanes. This AD was prompted by reports of iced angle-of-attack (AoA) probes after take-off, with associated misleading airspeed indication and/or misleading stall warning. This AD requires revising the existing airplane flight manual (AFM) to provide the flightcrew with updated procedures related to manually activating heating of the AoA probes during line up, 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.
