The FAA's summary their words, unchanged
These special conditions are issued for certain Dehavilland DHC-7-102 and 103 airplanes modified by Field Aviation Co., Inc. These airplanes are equipped with high-technology digital avionics systems that perform critical functions. The applicable 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 provide the additional safety standards that the Administrator considers necessary to ensure that the critical functions performed by these systems are maintained when the airplane is exposed to HIRF.
