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.
["Harakka I (H-12)"] 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,
["Grunau 9 ja PIK-7 Harakka, kerhon 1940-50-lukujen alkeiskoulukoneet"] becoming a standard piece of equipment in the clubs.

In 1946, Raimo Häkkinen and Juhani Heinonen from
Polyteknikkojen Ilmailukerho Polyteknikkojen Ilmailukerho (PIK) is the student flying club of the Aalto University. As well as a flying club, it develops light aircraft and gliders, often on a small scale but sometimes its designs have been produced in quantity. Approximately ...
redesigned the Harakka to strengthen it.
["PIK-sarjan lentokoneet"] This improved version became known as the Harakka II or PIK-7.
["PIK-sarjan lentokoneet"][Taylor 1989, p.726]["Harakka II (H-57)"] In 1948, a single example of a more radically redesigned version designated Harakka III flew.
["Harakka III/PIK-7 (H-34)"] This had the framework that supported the tail replaced by a single boom.
Examples of the Harakka I and Harakka II are preserved at the
