The MB.320 was a low-wing cabin monoplane powered by two wing-mounted Continental E185 engines.
It had room for a pilot and five passengers. The aircraft flew well, but was expensive to buy and with only a small domestic market for the type only a small number were exported. Three aircraft were sold to East African Airways for use as feederliners. They were all sold locally.
