11/30/2013. Remarks by Johan Visschedijk: "Pilatus Flugzeugwerke AG at Stans, Switzerland announced the single-turboprop pressurized utility/business transport PC-12 at the NBAA Show in October 1989. The first prototype (HB-FOA c/n P.01) was flown May 31, 1991, followed two years later by the second prototype (HB-FOB c/n P.02), May 28, 1993. Swiss certification was received on March 30, 1994, followed by the FAA approval on July 15, and deliveries began in September 1994. Presently over 1,100 of the 1,200 aircraft sold have been delivered, of which 245 are registered in the USA.

During the Financial Years 2004 to 2008 the USAF has bought at least 30 examples as the U-28A (PC-12/45) and U-28B (PC-12/47). Usually void of nationality markings, these are used for intra-theatre support of special operations forces. Additionally there is also unknown number of PC-12s with an FAA registration, that have been operated by Special Operations Command."
