The FAA's summary their words, unchanged

These special conditions are issued under Secs. 21.16 and 21.101(b) of the Federal Aviation Regulations (FAR) to become part of the certification basis for the supplementary type certification of the Ballistic Recovery Systems, Inc., General Aviation Recovery Device (GARD) modifications to Cessna 150/A150 Series and 152/A152 Model Airplanes. This system is referred to as the GARD-150. These modifications have novel or unusual design features associated with a parachute recovery system for which the applicable airworthiness regulations do not contain adequate or appropriate safety standards. These special conditions contain additional airworthiness standards which the Administrator finds necessary to establish a level of safety equivalent to that provided by the airworthiness standards applicable to these airplanes.
