Description

The FAA is adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 2000EX airplanes. This AD was prompted by a report of simultaneous failures of the main DC buses powered by Generator 1 and Generator 2 after flap extension during approach. The directive requires revising the existing airplane flight manual (AFM) to address this unsafe condition. The AD affects 304 airplanes of U.S. registry and is effective May 11, 2026.
