FAA Proposes Airworthiness Directive for Dassault Falcon Jets Over Sliding Seat Risk
Why It MattersThe move shows how a single manufacturer-specific seat defect can trigger parallel EASA and FAA directives, forcing operators of affected business-jet fleets toward coordinated, cross-border compliance timelines.
What happened
The Federal Aviation Administration issued a notice of proposed rulemaking for a new airworthiness directive covering all Dassault Aviation Model FALCON 7X, MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes, published in the Federal Register on September 10, 2026. The proposed AD was prompted by reported occurrences of cabin seats sliding without passenger input.
Investigations found that the cabin seat track locking mechanism can jam in isolated conditions during taxi, take-off, and landing. If left uncorrected, the condition could cause an affected seat to fail to remain in its position during critical phases of flight, potentially resulting in injury to passengers. The proposed AD would require operators to modify or replace each affected seat — including single seat assemblies and double seat assemblies with part numbers and serial numbers listed in Tables 1 and 2 of Appendix 1 of EASA AD 2025-0200 — and would prohibit the installation of affected seats.
The action mirrors EASA AD 2025-0200, dated September 17, 2025, and corrected September 30, 2025, which the European Union Aviation Safety Agency issued to address the same unsafe condition. The FAA proposes to incorporate EASA AD 2025-0200 by reference in the final rule. The FAA has assigned docket number FAA-2026-8801 to this rulemaking, and comments must be received by October 26, 2026.
Industry impact & what to watch
This case follows a familiar cross-border pattern in business aviation safety oversight: EASA identifies an unsafe condition tied to a specific component, and the FAA follows with a mirrored directive for the same aircraft models operating under its jurisdiction. Because Falcon jets are certified and flown across both European and American fleets, a seat-track defect discovered in one regulatory system quickly becomes a compliance obligation in the other.
For operators, this means fleet planning now has to account for a mandated seat modification or replacement across five Falcon models, with the part numbers and serial numbers already defined by the EASA appendix the FAA proposes to adopt by reference. The comment period closes October 26, 2026, and the final rule's scope — and any compliance deadline it sets — will depend on what the FAA does with the input it receives before then.
