After the success with the school and sports aircraft AIR -1 through AIR - 6, the Yakovlev Collective presented the challenging task of building a two-seat aircraft, which should be faster with the same engine as the in use -seater fighter aircraft.

The fuselage was a strung tubular steel construction, the wing consisted of metal, had a very thin profile (8% thickness) and was partially covered with fabric. The struts and tension were profiled. The construction of the aircraft began in April 1932 and in the summer, the aircraft was ready to fly. On 19 November, the ambitious target speed has been reached (325 km / h), in the spring of the following year even 332 km / h were achieved. Flight testing was continued until 1934. This led to a serious incident, as a result of the then little-known phenomenon of flutter an aileron demolitions in flight. The test pilot J. I. Piontkowski managed to land the damaged machine. In examining the machine the design of the rudder hinge was considered faulty. A. S. Yakovlev was held responsible and fell from grace.
