Special Conditions: Avions Marcel Dassault-Breguet Aviation, Falcon 10; High-Intensity Radiated Fields (HIRF)

These special conditions are issued for the Avions Marcel Dassault--Breguet Aviation Falcon 10 airplane modified by Garrett Aviation Services. This modified airplane will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The modification incorporates the installation of a Universal Avionics EFI- 550 Flat Panel Flight Display System that performs critical functions. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for the protection of these systems from the effects of high-intensity-radiated fields (HIRF). 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.
