The Blume Bl.500 Bl.502 and Bl.503 were a family of four-seat light aircraft designed in West Germany by Dr Walter Blume in the late 1950s. Derived from his Arado Ar 79 the basic design shared by all models was that of a conventional low-wing cantilever monoplane with retractable tricycle undercarriage and all-metal construction. The Bl.500 prototype was built for Blume at the Focke-Wulf plant and was powered by a Lycoming O-320 engine of 112 kW (150 hp).
Made by Walter Blume (fighter ace).
