Special Conditions: Dassault Model Fan Jet Falcon, Fan Jet Falcon Series C, D, E, and F Airplanes; Model Mystere-Falcon 200 Airplanes; and Model Mystere-Falcon 20-C5, 20-D5, 20-E5, and 20-F5 Airplanes; High-Intensity Radiated Fields (HIRF)

These special conditions are issued for Dassault Model Fan Jet Falcon, Fan Jet Falcon Series C, D, E, and F airplanes; Model Mystere- Falcon 200 airplanes; and Model Mystere-Falcon 20-C5, 20-D5, 20-E5, and 20-F5 airplanes modified by Royal Air, 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 is the installation of new air data display units (ADDU) and a new air data sensor, which perform 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.
