Design and developments
The Couzinet 70 Arc-en-Ciel III ('Rainbow') was developed from the 1920s Couzinet 10 Arc-en-Ciel, which first flew on 7 May 1928, the Couzinet 11 and Couzinet 40. The slightly larger span Couzinet 70 was developed originally as a mail plane for use of Aéropostale's South Atlantic service. It was a low-wing monoplane with a fixed tailwheel landing gear. The aircraft was powered by three Hispano-Suiza 12Nb inline piston engines. The two wing mounted engines could be accessed in flight through tunnels in the wing. After route-proving in 1933 the aircraft was modified and re-designated the Couzinet 71 and entered service with Aéropostale in May 1934.
