The Bleriot-SPAD S.33 was a small French airliner developed soon after World War I. The aircraft was a biplane of conventional configuration whose design owed much to the Blériot company's contemporary fighter designs such as the S.20. Four passengers could be accommodated in an enclosed cabin within the monocoquefuselage, and a fifth passenger could ride in the open cockpit beside the pilot. A great success, the S.33 dominated its field throughout the 1920s, initially on CMA's Paris-London route, and later on continental routes serviced by Franco-Roumaine.
One interesting development was a sole example converted by CIDNA to act as a blind-flying trainer. A set of controls was installed inside the passenger cabin, the windows of which had been blacked out.
Improved version of the S.33, powered by a 370 hp (280 kW) Lorraine-Dietrich 12Da engine. 38 built and sold to the Franco-Roumaine Company.
S.48
A single S.33 temporarily re-engined in 1925, fitted with a 275 hp (205 kW) Lorraine 7M Mizar engine.
S.50
Luxury version with passenger cabin enlarged to six seats, fitted with a 300 hp (220 kW) Hispano-Suiza 8Fb engine. Three were converted from S.33s, plus two all-new aircraft.
