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

These special conditions are issued for Dassault Aviation Model Falcon Fan Jet, Falcon Fan Jet series D, -series E, -series F airplanes; and Mystere-Falcon Model 20-C5, -20-D5, -20-E5, -20-F5, and -200 series airplanes modified by Premier Air Center. These airplanes will have novel and unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The modification incorporates the installation of a Universal EFI-890 Electronic Flight Display System, the Collins Attitude-Heading Reference System, and a Computer Instruments Corporation (CIC) Air Data System. 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 thatestablished by the existing airworthiness standards.
