Jakowlew Ja-6 ( Russian Яковлев Я-6 , also AIR-6 , АИР-6) was the name of a three-seat light aircraft. It was developed by Alexander Jakowlew during his studies at the Military Academy of the Air Force in Moscow. It was the designer's first model to be built in series. The abbreviation AIR refers to the politician Alexei Ivanovich Rykow .

history

The Ja-6 (AIR-6) was Aeroflot's most frequently used aircraft on local routes in the early 1930s . It was valued for its robustness and reliability. In addition to the land version with fixed landing gear, there was also a version as a seaplane with floats. On May 23, 1937, the float version set an international record in the non-stop flight Kiev - Batumi over 1,297 km with a cruising speed of 124 km / h in 10 hours and 25 minutes. Of the 468 aircraft built, 20 were also equipped as medical aircraft.

Small airliner Yes-6

The Ja-6 can easily be confused with the Jakowlew Jak-6 - a mistake that happened to the publisher of the shown postage stamp from Mongolia from 1976.
