Development

The Potez 840 was an all-metal low-wing cantilever monoplane with a retractable tricycle landing gear. It had a crew of three and a cabin for 18 passengers. Powered by four 440shp (328kW) Turboméca Astazou II turborops two mounted on the leading edge of each wing. The prototype first flew on 29 April 1961, a second aircraft flew in June 1962 and had more powerful 600shp (447kW) Turboméca Astazou XII engines. The second prototype carried out a sales tour of North America and it was planned to build a batch of 25 aircraft but only two more prototype aircraft were built, one for static testing. The next two aircraft were designated the Potez 841 and they were powered by 550shp (417kW) Pratt & Whitney of Canada PT6A-6 turboprops. Two more modified Aztazou-powered aircraft were produced, one in 1965 and one in 1967.
