The Couzinet 70 Arc-en-Ciel III (en Rainbow) was developed from the 1920s Couzinet 10 Arc-en-Ciel and Couzinet 30. The Couzinet 70 was developed originally as a mail plane for use of Aéropostale's South Atlantic service. The aircraft 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.
A 3-seat touring aircraft with similar layout to the Arc en Ciel was produced as the Couzinet 101, powered by three 85 hp (63 kW) Pobjoy R radial engines. This was further developed as the Couzinet 103 with three 135 hp (101 kW) Salmson 9Adr radials engines which could carry two crew (or one pilot and passenger) and four passengers in a separate cabin. Only one of each type was built.
