The Xian Yunshuji Y-7 (also: Y-14) is a Chinese version of the Soviet short-haul passenger aircraft Antonov An-24 of the Xi'an Aircraft Company, developed by reverse engineering from 1987, with modified aerodynamics and seats for 48 to 52 passengers.
description
Development began in April 1966. The first flight of four prototypes took place on December 25, 1970. Approval was only obtained in January 1984, as the first machines did not achieve certification in 1977 due to the weak engines. In 1980 an improved version followed with WJ-5A-1 engines with 2,137 kW instead of the 1,879 kW original engines. In contrast to the Antonov, the Y-7 was initially powered by two Wongan WJ5E engines developed with the help of General Electric, and from 1998 (as the Y7-200A) by two Pratt & Whitney PT127J turboprops , each with 2,026 kW. The Chinese Air Force operates around 30 Y-7s, according to US estimates. A total of around 200 Y-7s were built, with the freight version Y7H-500 still being produced around 2009. Outside of China , the Y-7 is also operated in Iran , Cambodia , Laos and Mauritania and Zimbabwe .
In 1995, China tried to have the aircraft certified in the USA, but it did not succeed. After the Wuhan Air accident in 2000, the aircraft was also withdrawn from passenger transport in China.
