These special conditions are issued for the Pilatus Aircraft Ltd. model PC-24 airplane. This airplane will have a novel or unusual design feature associated with installation of a pressure fueling system with defuel capability. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
