Blériot-SPAD S.42

The Blériot-SPAD S.42 was a French biplane trainer aircraft of the early 1920s, developed by the Société pour l'aviation et ses dérivés (SPAD) from the prolific SPAD S.XIII fighter. Its operators were the French Aeronautical Service and the Imperial Iranian Air Force, which was reported in a British report of 1 July 1925 to have two operational aircraft, and only a few photographs of the type remain. The specification lists a crew of one, a length of 6.77 m, a wingspan of 8.65 m, a height of 2.65 m, an empty weight of 685 kg, a gross weight of 1,056 kg and a maximum speed of 175 km/h from one 130 kW Hispano-Suiza 8Ab water-cooled V-8 piston engine, with a range of 450 km.
