What the agency says
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 (GEN1), and Generator 2 (GEN2) after flap extension during approach. This AD requires revising the existing airplane flight manual (AFM). The FAA is issuing this AD to address the unsafe condition on these products.
