History

The prototype first flew in September 1946,"PIK-5c Cumulus (OH-151)" and testing continued until it was badly damaged in a crash in summer 1948Tiusanen 1952, P.12 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. However, this aircraft, now known as the PIK-5B, was destroyed in a crash in summer 1951. Again, it was rebuilt with modifications, particularly to the wing structure, resulting in the PIK-5C version. This version first flew on 5 July 1952, and went on to become the pattern for around 30 similar machines that would be built over the ensuing years.
