The Dewoitine D.33 was a single-engined low-wing monoplane aircraft built by the Dewoitine Company.[1][2] It is remembered for setting a long distance record on its first flight in 1930.[2]
Little is documented on the specifics and the basic model of the Dewoitine D.33, other than the fact that it had a fixed undercarriage, and was a low-wing Cantilever Monoplane.[3] There were three documented variations to the model, each of which was designed as a separate aircraft. This line of aircraft were regarded highly commercially before World War II, and they were influential in the establishment of the Dewoitine Company.[1]

[edit] D.33 Variants
- D.33.01 : First prototype.
- D.33.02 : Second prototype.
[edit] D.332
The Dewoitine D.332 was developed based on the original Dewoitine D.33.[3] A single-spar cantilever low-wing monoplane, the D.332 had fundamental resemblances to the original design.[4] Able to hold a total of eight passengers, the Dewoitine D.332 had a small, closed in cockpit, with an aerodynamic design and a rigid undercarriage. It was constructed purely from metal, and was built approximately three years after the original Dewoitine D.33 model, in 1933.[3][1]
The D.332 proved successful, ultimately achieving a best speed of over 250 kilometres per hour, and, during the initial tests, where it was flown by test pilot Marcel Doret,[4] the D.332 prototype successfully flew from Paris to Saigon. It did, however, crash on the return flight from Saigon, on 15 January 1935.[1][4]
[edit] D.333
In 1934, the Dewoitine D.333 was designed, built and flown for the first time. It was different from its predecessors in that it was constructed with a more spacious cabin, and could hold a maximum of 10 passengers.[4] The primary buyer of this model was Air France; however, two of the three planes bought by the latter crashed while flying the distance between Toulouse and Dakar.[1][4]
[edit] D.338
1935-6 saw the drafting and prototype of the Dewoitine D.338. This new model was built with retractable undercarriages, and could carry 22 passengers over a maximum of around 1950 kilometres. Fitted with 484.5 kW Hispano-Suiza V16/17 engines,[4] the D.338 could travel at a speed of up to 260 kilometres an hour.
The D.338 was the first truly successful model in the line, and became widely used by Air France, first for flights within Europe, and later for international flights, between France and various parts of Asia. A total of 31 D.338s were purchased by Air France, and they were used into World War II, where they were employed as troop transporters. Following their use in the War, only eight aircraft survived.[4] However, despite this, the basic model was still used for years, until more recent builds were designed.
[edit] D.342 and D.620
Dewoitine designed two one-off aircraft based on the D.33 line; the D.342 and the D.620. Very few details relating to the specifics of these two aircraft are known or documented. Both were heavily based on the D.338 in particular.[4]
