The Dewoitine D.338 was a 1930s French 22-passenger airliner built by Dewoitine.

Design and development[edit]

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.
