The PIK-5 was a training glider produced in Finland in the 1940s, and 1950s,[1] equipping the country's gliding clubs with an aircraft greater in performance than primary gliders but less than competition sailplanes.[2]
The PIK-5 had a pod-and-boom configuration, with a high, strut-bracedmonoplanewing and a cruciform tail carried at the end of a tail boom that extended from a position high on the aft end of the pod.[3]
The prototype first flew in September 1946,[4] and testing continued until it was badly damaged in a crash in summer 1948[5] Over the subsequent months, the wings were repaired, and a new fuselage constructed to a revised design. This was completed the following winter, and flights recommenced.[5] However, this aircraft, now known as the PIK-5B, was destroyed in a crash in summer 1951.[5]
Again, it was rebuilt with modifications, particularly to the wing structure, resulting in the PIK-5C version.[5] This version first flew on 5 July 1952,[5] and went on to become the pattern for around 30 similar machines that would be built over the ensuing years.[4]
