Designed as a high-decker with two turbopropturbines, with a two-man cockpit, retractable landing gear and rear loading ramp. The PC-10 Masterporter was a project for a military cargo plane. Development of the PC-10 was later transferred to Poligrat but little progress was made. Externally, the latter two designs regarding chassis, wings and engine assembly resembled strongly the DHC-6 Twin Otter, but the tailplane difference to an enlarged version of the Pilatus PC-6 and Pilatus PC -8 Twin Porter used that has no sweep. It had been equipped with a fixed landing gear and two Garrett TPE-331 or Pratt & Whitney PT6A-27 turboprop engines. The machine should be able to transport 16 people, or nearly 2 tons of cargo. The aircraft would have a total length of 13.50 m, a height of 6.08 meters and a wingspan of 19 meters.

For it in the rear fuselage a loading door was built. Under the name Twin Project PC-10 is a slightly larger plane was designed which possessed on the left rear fuselage just a passenger sliding door that opens to the rear. A projected total length of 11.44 m and a height of 4.75 m with a span of 16 m. Under the name PC-10 MiniTwin a machine was designed for 11 people, on the left rear side of the hull with a cargo door with integrated passenger door. The first draft was basically an unchanged Pilatus PC-8D Twin Porter, the place of the piston engines would have been equipped with turboprop.
