   Aircraft description    

       Yak-40 was the first jet airplane in Russia and in the world designed specifically for passenger and cargo-passenger services on local routes. It was also the first Russian airplane that was issued an airworthiness certificate by other European countries. Yakovlev Design Bureau started to develop Yak-40, its first passenger aircraft, in 1965. Yak-40 was to replace the outdated LI-2, IL-12, and IL-14. The first trial flight took place on October 21, 1966, and the aircraft went into series production in 1968. Saratov aircraft factory has produced the total of 1011 airplanes, of which 125 were exported to 18 countries.
  In process of Yak-40 design Yakovlev Design Bureau made provision for the excessive safe load factor. Takeoff and landing characteristics of Yak-40 allow operating the aircraft on unpaved runways.
In terms of the external configuration Yak-40 is a monoplane with a cantilevered low-mounted wing, a retractable tricycle nose landing gear, and rear engines with the reverser installed on the central one. The specific load on the wing of this airplane is low while its overall ascensional power is very high. The airplane is equipped with three turbojet engines AI-25. Two of them are pylon-mounted in the fuselage tail section, and the third one is installed inside it. High power-to-weight ratio enables this aircraft to take off on high-level aerodromes (up to 2,500 meters above mean sea level) in hot weather.
  The passenger cabin of the basic configuration has capacity of 32 passengers. The re-equipped Yak-40 with the new interior designed and produced by InterAMI Corporation implements the concept of personal air transportation, highly comfortable and fully adjusted to all needs and requirements of VIP-passengers.
