Special Conditions: Dassault Model Falcon 10 Series Airplanes; High Intensity Radiated Fields (HIRF)

These special conditions are issued for the Dassault Model Falcon 10 series airplanes. These airplanes, as modified by Frederick A. Whitson, 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 the IS&S Digital 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 that provided by the existing airworthiness standards.
