Development and design

In 1957, the Argentine aircraft designer Alfredo Turbay began work on a twin-engined STOL light transport, the Turbay T-3A, with Turbay S.A. formed at Buenos Aires in January 1961 to build the new design.[1][2] The T-3A was a low-wing cantilever monoplane of all metal construction. It was powered by two 130 kW (180 hp) Lycoming O-360-A1D air-cooled four-cylinder horizontally-opposed engines driving two-bladed propellers, and was fitted with a retractable nosewheel undercarriage.[1]

Alfredo Turbay piloted the T-3A on its first flight on 8 December 1964.[1] Production was planned of the T-3B, which was to be fitted with 190–260 kW (250–350 hp) Lycoming or Continental engines, giving improved performance.[1][3] These plans did not come to fruition, with the prototype T-3B never completed, and no production occurring.[4]
