The Harakka ("European magpie") was a primary glider produced for pilot training in Finland in the 1940s. Its design was typical of this class of aircraft, a "keel" with a pilot's seat suspended beneath a high, strut-braced monoplane wing, and carrying a conventional empennage at the end of an open framework.[1] First flown in February 1945, the type was built from plans by Finnish gliding clubs and soon replaced earlier primary gliders such as the Grunau 9,[2] becoming a standard piece of equipment in the clubs.[1][3]
In 1946, Raimo Häkkinen and Juhani Heinonen from Polyteknikkojen Ilmailukerho redesigned the Harakka to strengthen it.[4] This improved version became known as the Harakka II or PIK-7.[4][5][6] In 1948, a single example of a more radically redesigned version designated Harakka III flew.[7] This had the framework that supported the tail replaced by a single boom.[7]
Examples of the Harakka I and Harakka II are preserved at the Suomen ilmailumuseo[8] and the Karhulan ilmailukerho Aviation Museum,[1][6] with the sole Harakka III also preserved at the latter museum.[7]
