Special Conditions: Cessna Aircraft Company Model 650 Citation III Airplanes; High Intensity Radiated Fields (HIRF)

These special conditions are issued for Cessna Aircraft Company Model 650 Citation III airplanes modified by Pro Star Aviation, LLC. 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 Honeywell Primus Epic Control Display System (CDS)/Retrofit Electronic Flight Instrument System (EFIS) system, and a second air data computer. 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.
