Airworthiness Directives; Dassault Aviation Airplanes
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
The FAA is issuing Airworthiness Directive (AD) 2026-07-02 for certain Dassault Aviation Model FALCON 2000EX airplanes. This directive was prompted by a reported incident of simultaneous failures of the main DC buses powered by Generator 1 and Generator 2 after flap extension during approach. The failures caused intermittent crew alerting system messages including the red "2 GEN'S FAIL" warning, data flickering on display units, and flashing lights on the overhead panel. This AD requires operators to revise the existing Airplane Flight Manual (AFM) to include emergency procedures addressing these issues. The unsafe condition, if unaddressed, could increase pilot workload during critical flight phases. The AD becomes effective on May 11, 2026.
