Special Conditions; Tiger Aircraft, EFIS on the AG-5B; Protection of Systems for High Intensity Radiated Fields (HIRF)

These special conditions are issued to Tiger Aircraft, 266 Pilot Way, Martinsburg, WV, 25401, for a change to the Type Design of the Tiger AG-5B. 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 an electronic flight instrument system (EFIS) in the form of a Garmin G1000 integrated avionics system. The current applicable regulations do not contain adequate or appropriate airworthiness standards for the protection of the 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.
