The FAA's summary their words, unchanged
These special conditions are issued for certain Convair Model 340 or 440 airplanes, modified by the Allison Gas Turbine Division of General Motors Corporation. These airplanes, which have been modified previously to incorporate Allison 501 series turbopropeller engines, are equipped with high-technology digital avionics systems that perform critical and essential functions. The applicable regulations do not contain adequate or appropriate safety standards for the protection of these systems from the effects of lightning and high-intensity radiated fields (HIRF). These special conditions contain the additional safety standards that the Administrator considers necessary to ensure that the critical and essential functions that these systems perform are maintained when the airplanes are exposed to lightning and HIRF.
