Notice of proposed rulemaking (NPRM).
Summary
The Federal Aviation Administration (FAA) is proposing a safety rule that would require owners of certain Dassault Falcon business jets to modify or replace cabin seats that have been found to slide unintentionally. The issue was discovered when the seat‑track locking mechanism occasionally jammed during taxi, take‑off, or landing, creating a potential hazard for passengers. By mandating the repair and banning the re‑installation of the faulty seats, the FAA aims to prevent future incidents and keep the aircraft’s cabin safe. The rule applies to all Falcon 7X, Mystère‑Falcon 900, Falcon 900EX, Falcon 2000 and Falcon 2000EX airplanes operating in the United States. It is being issued by the Department of Transportation’s FAA, the agency responsible for civil aviation safety. The notice was published on September 10, 2026, and the public has until October 26, 2026, to submit comments on the proposal. After the comment period closes, the FAA will review the feedback and, if it proceeds, will issue a final airworthiness directive that sets a compliance timeline for the seat modifications. Operators will then be required to complete the work within the timeframe specified in the final rule.

Official abstract
The FAA proposes to adopt a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X, MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. This proposed AD was prompted by reported occurrences of seats sliding without passenger input. The cabin seat track locking mechanism was found to jam in isolated conditions during taxi, take-off, and landing (TTOL). This proposed AD would require modifying or replacing each affected seat. This proposed AD would also prohibit the installation of affected seats. The FAA is proposing this AD to address the unsafe condition on these products.
