The FAA's summary their words, unchanged

These special conditions are issued to become part of the type certification basis for the Fairchild Aircraft Corporation Models SA227-CC, SA227-DC, and SA228-AE Airplanes to be certified as a commuter category airplane. The commuter category certification standards require an emergency evacuation demonstration, but it does not contain a requirement for emergency lighting to aid in emergency evacuation. When an applicant chooses to install an emergency lighting system and use it during the required evacuation demonstration, appropriate standards must be adopted to assure the system performs its functions when the critical event occurs. These special conditions contain the additional airworthiness standards which the Administrator finds necessary to establish a level of safety equivalent to the airworthiness standards applicable to these airplanes.
