The People’s Republic of China imported the Antonov An-24 from early in its production run and also negotiated licences for production of the aircraft and its engines. In 1966, Xi’an aircraft factory started the project of local production of An-24. The first Chinese-assembled An-24T had its maiden flight on 25 December 1970. Production was launched in 1977 at the Xi’an aircraft factory but progress was slow due to the deleterious effects of the Cultural Revolution, with a pre-production aircraft displayed to the public at Nanyuan air base, near Beijing, on 17 April 1982. The WJ-5A1 turboprop engine was chosen as the Y-7’s power source. The first production aircraft was not flown until February 1984, illustrating the slow progress (eighteen years from licence to production)
