The Sperling was the first design of powered aircraft to come from the Scheibe Flugzeugbau company which had started building gliders in 1951. The prototype first flew on 8 August 1955 and the initial production SF-23A aircraft first flew in September 1958. [1]

The Sperling is a high-wing braced monoplane with side-by-side seating for two in an enclosed cabin. [2] It had a fixed tailwheel landing gear and was initially powered by a 95 hp (71 kW) Continental C90 piston engine. [2] [3] The Sperling utilizes mixed construction, the fuselage being a fabric-covered steel-tube structure and the wings being single-spar wooden structures with fabric and plywood covering. Production of the Sperling was completed in 1963. [1]

Operation

Most aircraft produced were sold to German private pilots and flying clubs but one was purchased by a British owner. The higher powered versions were suitable for use in glider-towing. By 2009, seven examples remained in active operation in Germany. [4]

The Klemm Kl 107 was a two-seat light aircraft developed in Germany in 1940. It was a conventional low-wing cantilever monoplane of wooden construction with fixed tailwheel undercarriage. Wartime production totalled only five prototypes and some 20 production machines before the Klemm factory was destroyed by Allied bombing. Following World War II and the lifting of aviation restrictions on Germany, production recommenced in 1955 with a modernised version, the Kl 107B, of which Klemm built a small series before selling all rights to the design to Bölkow. This firm further revised the design and built it as the Kl 107C before using it as the basis for their own Bo 207.
