The FAA's summary their words, unchanged

These special conditions are issued to Learjet Inc. of Wichita, KS, for the Learjet Inc., Model 45 airplane. This new airplane has an unusual design feature associated with an unusually high operating altitude (51,000 feet), for which the applicable airworthiness regulations do not contain adequate or appropriate safety standards. 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.
