Yak-10 family of light aircraft by A.S.Yakovlev (NATO 'Crow')


H
igh wing liaison/commuter aircraft with 5-cylinder radial engine. Yak-10 (project stage designation - Yak-14) was a development of pre-War AIR-5, AIR-6 and AIR-6A with 4-seat cabin. Fuselage frame - steel tubes, wing - wood, all skin - fabric. Construction was light enough to lift pilot and three passenger with 10kg luggage.
Aircraft was ready in January 1945 and passed the trials in June 1945. Performance was found good, handling and service - easy. Series production followed, some Yak-10 were built in Yak-10V variant. Vyvosnoj (trainer) variant had dual set of controls.
In 1946 more powerful M-11FR was installed. Performance got even better. Yak-10G (Gidroplane, Hydroplane) on AIR-6-type floats was built. Performance was poor, trials were not finished.
In 1947 paramedic Yak-10S 'Sanitarnyj' entered production with large triangular on port side. Aircraft weight was not changed, and 1 or 2 patients on stretchers could be accommodate with one medical personal. In February Yak-10 was installed on skis (wooden with metal kingpost, made in Canada). Despite skis were quite lightweight (20.25kg each of two main and 1.93kg the tail one) performance was found intolerably harmed due to badly degraded airdynamic. Ski-mount Yak-10 could operate only well prepared snow-covered fields, what made it unacceptable for rural areas.
About 40(?) were built.
