The FAA's summary their words, unchanged
These special conditions are issued for Douglas Model DC-9-14, DC-9-15, DC-9-31, DC-9-32, DC-9-32F, DC-9-33F, and DC-9-41 airplanes modified by ABX Air Inc. These modified airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The modification incorporates the installation of the Innovative Solutions and Support (IS&S) Duplex Reduced Vertical Separation Minimum (RVSM) system that performs critical functions. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for the protection of this system 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 that established by the existing airworthiness standards.
