[1] The resulting design, the Beijing 1, was a small twin-engined low-wing cantilever monoplane with a retractable tricycle landing gear and of all metal construction.
It was powered by two 190-kilowatt (250 hp) Ivchenko AI-14 driving two-bladed wooden propellers, while its wings were fitted with leading-edge slats and trailing edge flaps to ease operations out of small airfields.
[1] The Beijing 1 made its maiden flight on 24 September 1958, and was handed over to the Chinese civil aviation authorities on 1 October 1958, the 9th anniversary of the establishment of the People's Republic of China.
[1][nb 1] Although contemporary reports suggested that the type entered service with Civil Aviation Administration of China,[6] no production followed, with only the single prototype being built.
