Southern Aero Sports Scorpion
The Scorpion was grounded by the UK Civil Aviation Authority. This followed a series of three in-flight structural failures, two on single-seaters and one on a two-seater, which resulted in three deaths and one serious injury. Subsequent investigation by the Accident Investigation Branch revealed a lack of torsional stiffness in the main structural components, as well as a poor standard of detail engineering. The company went into liquidation shortly after the accidents. By 1982 were no longer trading.
Between 30 and 40 Scorpions were made, in various guises, all using Robin engines of either 330 or 440 cc.
