Following the success of the Klemm Kl-107-derived Bo 207, Messerschmitt-Bolkow launched a new two-seat touring/training light aircraft to complement the single-seat Bo 208 Junior, and this was later named the Monsun (designated Bo 209). The Monsun has a 'side by side' seat configuration, a tricycle undercarriage, folding wings for easy storage and the nose wheel is retractable in later versions. About 100 of the type were produced (and more than 270 orders were in place) until 1972, when production of this light aircraft ended.
