The FAA's summary their words, unchanged

These special conditions are issued for the SAAB Model 2000 airplane. This airplane will utilize electrical and electronic systems which perform critical and essential functions. These systems include electronic displays which present critical and essential flight and engine parameters to the flightcrew, and electronic propulsion and propeller controls. 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 provide the additional safely standards which the Administrator considers necessary to ensure that critical and essential functions that these systems perform are maintained when the airplane is exposed to lightning and HIRF.
