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

These special conditions are issued for Dassault Model Mystere-Falcon 20-C5, 20-D5, 20-E5, and 20-F5 series and Dassault Model Fan Jet Falcon series C, D, E, F, and G airplanes modified by Genesis3 Engineering. These modified 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 an Innovative Solutions & Support (IS&S) Dual Air Data Display Unit (ADDU) and an Air Data Sensor Unit (ADS). 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 provided by the existing airworthiness standards.
