What it does

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.
