The Dewoitine D.338 was a 1930s French 22-passenger airliner built by Dewoitine. The D.338 was a development of the D.333 with retractable undercarriage. First flown in 1936 it had a slightly increased wingspan, and the fuselage was lengthened by 3.18 m (10 ft 5¼ in). For short routes, the aircraft could carry 22 passengers, aircraft used in the Far East were fitted with 12 luxury seats, including six that could be converted into sleeping berths. In the late 1930s Air France used the D.338 on its transcontinental route to French Indo-China, connecting Paris and Saigon. In 1939 the service was extended to Hong Kong. The D.338 had a reputation for reliability and was used during World War II in the French overseas possessions. Nine aircraft that survived the war were operated on the Paris-Nice service for several months. Variants D.338 Main production version, 30 built.
