The Macchi MB.308, later Aermacchi MB-308, was a light aircraft produced in Italy in the late 1940s, one of the most prolific Italian-built types of the following decade. It was a conventional high-wing cantilever monoplane with fixed tricycle undercarriage. Construction throughout was of wood. The pilot and a single passenger or instructor sat side by side, and later examples had a third seat behind them. The MB.308 was ordered in quantity by the Aeronautica Militare, which leased them out to Italy's aeroclubs. A modified version with a higher-powered engine was put into production in Argentina, under licence to sailplane manufacturer German Bianco. Variants MB.308 - main production version with Continental C85 engine MB.308 Idro - seaplane version MB.308G - three-seat version with Continental C90 engine MB.308G-100 - MB.308G built in Argentina with Continental O-200 engine and fuel tanks relocated from fuselage to wings
