The first was by the German firm Pneuma-Technik E. Ficht, which established Monson Gmbh to produce the type at Weiden, Bavaria, but only two aircraft were finished before production ended during June 1974.

[1][2] The needs and preferences of international aviators, such as in the North American market, was taken into account during this design process, a focus that led to the future aircraft possessing a high degree of versatility.

Amongst other things, it was designed to be stored in domestic garages rather than hangars (as an economy measure) as well as the ability to retract the nose gear on the ground to better permit it to be towed.

While the MHK-101 shared several components of the preceding Bo-208, it had a larger and more comfortable cockpit, and an entirely new wing, which could be folded for towing and storage (the Bo 208 was a high-wing aircraft).

Optional equipment has included a transponder, navcom, VHF omnidirectional range, automatic direction finder, ice detector, emergency locator beacon, and various audio systems.

[4] On 22 December 1967, the first prototype MHK-101, powered by a 125 hp (93 kW) Lycoming O-235 engine driving a fixed-pitch propeller and with a retractable nosewheel, performed its maiden flight.

[14] During the mid-1970s, an American businessman opted to invest in the Bo 209; this scheme did progress to the extent that funding was secured and the shipping of both factory equipment and inventory to Georgia had commenced with the intention of producing the type in the US.

[8] While further approaches were made by prospective investors to resume production of the type, MBB’s management was reportedly reluctant to commit to such proposals.
