The SIPA S.70 was a late 1940s France eight-passenger light transport aircraft prototype built by Société Industrielle Pour l’Aéronautique (SIPA).[1]
Design and development
The design for a commercial light transport for inter-city routes was started in 1947, the S.70 was a wooden, twin-engined, low-wing cantilever, cabin monoplane with a twin tail.[1] Powered by two 210 hp (157 kW) Mathis G.8R piston engines it had room for six to eight passengers with a pilot sat centrally at the front.[2] The prototype, registered F-WZCI, was flown in 1949 but very little else is known and it did not enter production.[1]
