Special Conditions: Dassault-Aviation Mystere-Falcon 50 Airplanes; High-Intensity Radiated Fields (HIRF)

These special conditions are issued for Dassault-Aviation Mystere-Falcon 50 airplanes modified by Chippewa Aerospace, Inc. These modified airplanes 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 Honeywell Primus Epic Control Display System for Retrofit (CDS-R) 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.
