## Summary

We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 2000, FALCON 2000EX, MYSTERE- FALCON 900, and FALCON 900EX airplanes. This proposed AD was prompted by reports of a co-pilot sliding aft on his seat during take-off at rotation. This proposed AD would require replacement of certain springs installed on the pilot and co-pilot seats. We are proposing this AD to prevent fatigue wear, which, if not corrected, could cause the seat to slide and the pilot or co-pilot to lose contact with the controls, leading to an inadvertent input on the flight control commands during take-off or climb, possibly resulting in loss of control of the airplane.
