Special Conditions: Dassault Falcon Model 900 and 900EX Airplanes; Interaction of Systems and Structures

These special conditions are issued for the Dassault Falcon Model 900 and 900EX airplanes. These airplanes, as modified by Aviation Partners Incorporated (API), will have a novel or unusual design feature associated with the interaction of systems and structures regarding installation of an automated wing-load-alleviation system. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. For the Dassault 900 and 900EX models with winglets, failure of the wing-load- alleviation system can result in a factor of safety (FS) below 1.5 as required. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
