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]
Operationedit
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]
