The IVL A.22 Hansa was the Finnish license production of the German Hansa-Brandenburg W.33 , a sea reconnaissance seaplane.
History and construction
The Hansa-Brandenburg L.33, a two-seat monoplane with an open cockpit, was developed by Ernst Heinkel in 1916 and used by German naval aviators from 1918. 26 copies were built, but only six before the end of the war. Noticeably better than the Friedrichshafen FF 33 , it turned out to be an excellent aircraft. The Hansa-Brandenburg monoplane had a considerable influence on German seaplane development, and several similar machines appeared in 1918, such as the Friedrichshafen FF 63 , the Dornier Cs I , the Junkers J 11 or the LFG Roland ME 8 .
Finland bought a series of L.33 and L.34 from Germany and in 1921 it also acquired the license to manufacture the L.33. The first Hansa built in Finland made its maiden flight on November 4, 1922 and was called A.22 . This aircraft was Finland's first industrially manufactured aircraft. A total of 120 aircraft were manufactured in the following four years. The machine could also be equipped with skis instead of swimmers. The aircraft was so reliable that the last copies remained in service until 1936.
