The Piper PA-25 Pawnee was one of the first single seat light aircraft to be specifically designed and built for agricultural spraying and dusting. It was also one of the most successful, with several thousand built, and with licence production in a number of countries.
The PA-25 Pawnee was originally designed by Fred Weick as the AG-3, and flew in prototype form during 1957. The design was originally powered by a 110kW (150hp) Lycoming O-320, the fuselage structure was designed to absorb impact forces in a crash, the high cockpit had excellent all round vision, the braced wing was fitted with spray bars, while a jump seat could be fitted in the hopper.
