The FAA's summary their words, unchanged
This special condition is issued for the Boeing Model 727-100 airplane. This airplane, as modified by Associated Air Center, utilizes new avionics/electronic systems, such as the electronic flight information systems (EFIS), which 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). This special condition contains the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
