In 1932, the Soviet aircraft designer Alexander Sergeyevich Yakovlev, working as an engineering supervisor at the Polikarpov OKB, designed the AIR-5,[nb 1] a five-seat high-winged monoplane with a steel-tube fuselage and a wooden wing, powered by an American Wright J-4 Whirlwind radial engine giving 149 kW (200 hp). Although the AIR-5 successfully passed State acceptance trials, no production followed, as there was no suitable Soviet replacement for the imported engine.[2][3]
Yakovlev instead designed a scaled-down aircraft of similar layout to the AIR-5, but powered by a readily available 75 kW (100 hp) Shvetsov M-11 engine, to serve as a light utility aircraft. The new design, the AIR-6, was a high-winged monoplane using much of the structural design of the AIR-5, (and also featuring landing struts from the Polikarpov U-2 and tail surfaces from the Tupolev I-5 fighter), with a pilot and one or two passengers sitting in tandem in an enclosed cockpit.[4][5]
The prototype AIR-6 flew in 1932, passing state acceptance trials in October 1933.[6] An accident with the Yakovlev AIR-7 sport aircraft, however, was blamed on a design error by Yakovlev, who was sacked from the Polikarpov design bureau.[7] This caused production plans to be delayed until Yakovlev was allowed to set up his own design bureau, with production starting in 1934. A total of 128 AIR-6s were built, with several being fitted with floats, and 20 equipped as specialist ambulance aircraft.[8]
