The Pilatus PC-12 is a single-engine turboprop passenger and cargo aircraft manufactured by Pilatus Aircraft of Switzerland. The main market for the aircraft is corporate transport and regional airliner operators. The U.S. Air Force's designation is the U-28A. The PC-12 holds the distinction of being the best selling pressurized, single-engine, turbine-powered aircraft in the world.

In October 1989, Pilatus announced the development of the PC-12 at the annual convention of the National Business Aviation Association (NBAA). Prior to the 1989 announcement, the PC-12 project had been worked on for some time under high levels of secrecy; by the time of the announcement, assembly of the first prototype had already commenced.[7] Pilatus believed that the PC-12 would fit a new market not served by existing aircraft, and that the type would be the first single-engine aircraft capable of a large volume at high speed across long distances.

Since entering service, Pilatus developed a large number of improvements and options upon the original PC-12 model; amongst these changes include increases in the maximum takeoff weight, the use of increasingly powerful engines, the adoption of new avionics, noise-reduction measures, new propellers, speed and range increases, additional interiors, and new in-flight entertainment systems. Other aviation firms, such as Finoff Aviation Products, have also produced their own independent products and aftermarket enhancement packages for the PC-12.
