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. Bölkow had built the Kl 107 under licence before substantially modernising and enlarging the design. Development commenced with the modification of a Bölkow-built Kl 107 (construction number 145) into a prototype that first flew at the end of 1960. Changes to the earlier aircraft included a revised cockpit canopy, the addition of wing fuel tanks, and two extra seats.
Altogether, 91 aircraft were produced in series, in addition to the prototype. One of these (construction number 284) was built with tricycle undercarriage, and designated Bo 214.
