Special Conditions; Cessna Aircraft Company Model 208B, Garmin G1000; Protection of Systems for High Intensity Radiated Fields (HIRF)

These special conditions are issued to Cessna Aircraft Company, for an amended type certificate for the Model 208B airplane. This airplane will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards. These novel and unusual design features include the installation of electronic flight instrument system (EFIS) displays model G1000 manufactured by Garmin for which the applicable regulations do not contain adequate or appropriate airworthiness 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 the airworthiness standards applicable to these airplanes.
