FAA to Falcon Jet Owners: Update Your Manual or Risk Flap Failures!
Published Date: 4/6/2026
Rule
Summary
If you fly a Dassault Falcon 2000EX, listen up! The FAA found a problem where both main power systems can fail during landing flaps, so they’re updating the flight manual to keep things safe. This change kicks in on May 11, 2026, and it won’t cost a fortune—just a quick manual update to keep your flight smooth and secure.
Analyzed Economic Effects
4 provisions identified: 2 benefits, 2 costs, 0 mixed.
AFM Revision Required for Falcon 2000EX
If you operate a Dassault Falcon 2000EX airplane, the FAA requires you to revise the airplane flight manual (AFM) as specified in EASA AD 2025-0042 to address simultaneous failures of the main DC buses after flap extension. This AD is effective May 11, 2026.
Per-Airplane Compliance Cost Estimate
The FAA estimates compliance takes 1 work-hour at $85 per airplane and $0 in parts, for a cost of $85 per airplane. The AD affects 304 U.S.-registered Falcon 2000EX airplanes for a total estimated cost on U.S. operators of $25,840.
Small Entities Affected, De Minimis Impact
The FAA says this AD will affect 230 small and non-small entities (including 143 small entities) and that the compliance cost per small entity relative to annual revenue is de minimis. The FAA certified the AD will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act.
No Reporting or Downtime Required
The AD does not require any reporting under the Paperwork Reduction Act, and the FAA determined AFM revisions are administrative actions that will not trigger downtime costs or burdensome scheduling disruptions.
