The FAA's summary their words, unchanged

These special conditions are issued pursuant to 21.16 and 21.101 of the Federal Aviation Regulations (FAR) to McDonnell Douglas for the Model DC-9-80 and MD-80 series airplanes. These series airplanes will have novel or unusual design features associated with the installation of new electronic systems for which the applicable airworthiness regulations do not contain adequate or appropriate safety standards for protection from the indirect effects of lightning. These special conditions contain the safety standards which the Administrator finds necessary, because of these added design features, to ensure that the functions of these systems, which are critical and essential, are addressed.
