Airworthiness Directive · Amendment 39-18501 · Equipment/furnishings
Dassault Aviation Airplanes
This AD applies to the airplanes identified in paragraphs (c)(1), (c)(2), (c)(3), and (c)(4) of this AD, certificated in any category, equipped with SICMA 132-series or 142-series pilot and co-pilot seats.
(1) Dassault Aviation Model FALCON 2000 airplanes.
(2) Dassault Aviation Model FALCON 2000EX airplanes.
(3) Dassault Aviation Model MYSTERE-FALCON 900 airplanes.
(4) Dassault Aviation Model FALCON 900EX airplanes.
We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 2000, FALCON 2000EX, MYSTERE-FALCON 900, and FALCON 900EX airplanes. This AD was prompted by reports of a co- pilot sliding aft on his seat during take-off at rotation. This AD requires replacement of certain springs installed on the pilot and co- pilot seats. We are issuing 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.
For airplanes that have accumulated more than 3,750 total flight cycles or have exceeded 74 months since the airplane's first flight as of the effective date of this AD: Within 9 months after the effective date of this AD, replace each spring having part number (P/N) 132100-19 and P/N 147100-19 installed on the pilot and co-pilot seats with a spring as specified in, and in accordance with, the Accomplishment Instructions of the service information identified in paragraph (g)(1), (g)(2), (g)(3), or (g)(4) of this AD, as applicable. Repeat the replacement thereafter at intervals not to exceed 78 months or 3,750 flight cycles, whichever occurs first.
(1) Dassault Service Bulletin F900-429, Revision 1, dated July 13, 2012.
(2) Dassault Service Bulletin F900EX-446, Revision 1, dated July 13, 2012.
(3) Dassault Service Bulletin F2000-401, Revision 1, dated July 13, 2012.
(4) Dassault Service Bulletin F2000EX-267, Revision 1, dated July 13, 2012.
As of the effective date of this AD, installation of a spring having P/N 147100-19 or P/N 132100-19 on any airplane is allowed, provided that the spring is new.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
