Special Conditions: Avions Marcel Dassault-Breguet Aviation (AMD/BA) Model Falcon 10 Series AirPlanes; High-Intensity Radiated Fields (HIRF)

These special conditions are issued for Avions Marcel Dassault-Breguet Aviation Model Falcon 10 series airplanes modified by Garrett Aviation Services. These airplanes, as modified, 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 dual Innovative Solutions & Support Air Data Display Units (ADDU) with the IS&S Air Data Sensor and an analog interface unit (AIU) that 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.
