Bölkow had built the two and three-seat Kl 107 and developed a four-seat variant, at first designated the Kl 107D.
The low-wing cabin monoplane had a re-designed cockpit and canopy and a larger tail.
The two prototype Kl 107Ds were built at Nabern and the first flew on 10 October 1960.
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.
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.
The first of 90 production aircraft built at Laupheim was flown on 24 May 1961 and production continued until 1963.
