AIR-9 and AIR-9bis, A.S.Yakovlev
Two-seat low-wing monoplanes with fuselage frame made of wielded steel tubes. Mixed skin - fabric and plywood. Wooden wing was equipped with landing flaps and leading edge slats, since the original project was intended for the Safe Aircraft Contest (1933). Aircraft had open cockpits.
Project was seriously revised, and two aircraft were built. AIR-9 (in 1934) and AIR-9bis (in 1935) had long glazed canopy covering both seats. AIR-9bis had triangular canopy and Townend ring on the engine.
On July 4, 1937 AIR-9bis was used by women-pilots Irina Vishnevskaya and Ekaterina Mednikova to establish international record of altitude (6518m) for light aircraft. AIR-9bis was demonstrated at Milan aviation show (1935), and its sibling - at Paris airshow (1934).
