The FAA's summary their words, unchanged

These special conditions are issued for the Boeing Model 767- 300 and -300F airplane as modified by Aviation Partners Boeing Supplemental Type Certificate (STC). The modified airplane has novel or unusual design features involving installation of blended winglets and a speedbrake wing-load-alleviation system. This system reduces loading on the wing. The applicable airworthiness regulations for the Boeing Model 767-300 and -300F do not contain adequate or appropriate safety standards for systems which alleviate loads on structures. 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 applicable airworthiness standards.
