Blume Bl.502
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. This led to a modified version, the Bl.502 that achieved German type certification and was offered for sale alongside the generally similar Bl.503 with a more powerful engine. However, no orders were forthcoming and Blume abandoned the project.Operational history
The final example of the design, the Blume Bl.503 was still active in 1965.Variants
