Bölkow Bo 207
The Bölkow Bo 207 was a four-seat light aircraft built in Germany in the early 1960s, a development of the Klemm Kl 107 built during World War II.
Design and development
Bölkow had built the two and three-seat Kl 107 and developed a four-seat variant, at first designated the Kl 107D.[3] The low-wing cabin monoplane had a re-designed cockpit and canopy and a larger tail.[3] The two prototype Kl 107Ds were built at Nabern and the first flew on 10 October 1960.[3] With the change of name of the company to Bolkow and the move to new factory at Laupheim production of the new variant was started at the new factory.[3] In May 1961 the design was re-designated the Bolkow F.207 but by July 1961 it was re-designated again as the Bolkow BO 207.[3]
The first of 90 production aircraft built at Lauphein was flown on 24 May 1961 and production continued until 1963.[3][4] A number of aircraft remained unsold and the last aircraft although built in 1963 did not fly until 1 April 1966.[4] One aircraft was built with tricycle landing gear, and designated BO 217B or sometine known as the BO 214 but it was fitted with a conventional landing gear before it was sold.[4]
