Yakovlev Yak-42




__NOTOC__

The three engined Yakovlev Yak-42 was designed as a replacement for the twin engined Tupolev Tu-134 Jet . It fulfills a role similar to that of the Boeing 727 as a mid-range passenger jet. The Yak-42 was also the first airliner to be produced in the Soviet Union to be powered by modern high-bypass Turbofan engines.

To save design time, Yakovlev started with the Yak-40 , making it larger and sweeping back the wings, with an 11-degree sweep prototype being rejected in favor of a 23-degree sweep. The Yak-42 was built at Smolensk , and it entered service with Aeroflot in late 1980 . Almost 100 had been delivered by 1993 .

Shortly after the type's introduction into commercial service, a number of accidents caused by Vibration s in the tail section of the aircraft forced a suspension of the type's operations. After the necessary modifications were made, the Yak-42 re-entered service in the Soviet Union circa 1985 .

The type was never exported, and only after the political transition of the former Soviet Union, a few Yak-42s were leased out to carriers in Africa, Cuba, Pakistan and in former Yugoslavia .

Current models include the Yak-42 base version, the Yak-142 with a higher gross weight, and the '''Yak-42D-100''' with western avionics that never entered serial production. Late in 1997, Yakovlev announced the development of the '''Yak-42A''', an improved version of the Yak-42D featuring a higher range and a modernised cabin interior.
