Design and development

The Y-12 started life as a development of the Harbin Y-11 airframe. The design featured numerous improvements including a redesigned wing with a supercritical aerofoil section and bonded rather than riveted construction. The Y-12 II prototype first flew August 16 1984 and received Chinese certification in December of the following year. The powerplants are two Pratt & Whitney Canada PT6A-27 turboprops with Hartzell props. The Y-12 has a maximum payload of 5,700 kg (12,600 lb) with space for 17 passengers (2 crew). The aircraft is operated by China, several other countries in the region and in the South Pacific as a light commuter and transport aircraft.
