The FAA's summary their words, unchanged

This special condition is issued for the Gulfstream Aerospace Corporation Model GV, GV-SP, and GIV-X airplanes. These airplanes will have a novel or unusual design feature(s) associated with the use of a hydrophobic windshield coating, rather than windshield wipers, as the means to maintain a clear portion of the windshield during precipitation conditions, as required by the airworthiness standards for transport category airplanes. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. This special condition contains the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
