Aeronautica lndustriai sa / AISA GN
In 1974 Aeronautica Industrial SA (AISA) started construction of the prototype AISA-GN, which was an all-metal four-seat autogyro with a small stub wing, three-blade main rotor, twin booms and a fixed tricycle undercarriage. After a long development, the prototype was first flown on 20 July 1982, powered by a 225kW Lycoming IO-540-K-1A5 engine. The prototype was damaged in September 1982, and the project was then abandoned.
