The Harbin Y-12 is a high wing twin-engine turboprop utility aircraft built by Harbin Aircraft Industry Group (HAIG). The Y-12 started as a development of the Harbin Y-11 airframe called Y-11T in 1980. The design featured numerous improvements including a redesigned wing with a new low drag section, a larger fuselage and bonded rather than riveted construction. It also replaced the radial piston engines with turboprops. The prototype was followed by about 30 production Y-12 (I) aircraft before a revised version was produced. This was designated the Y-12 (II), which featured more powerful engines and removal of leading-edge slats, first flying on 16 August 1984 and receiving Chinese certification in December of the following year. The power plants are two Pratt & Whitney Canada PT6A-27 turboprops with Hartzell propellers. The Y-12 has a maximum takeoff weight of 5,700 kg (12,600 lb) with seating for 17 passengers and two crew. The aircraft is operated as a light commuter and transport aircraft.
📑 ➖➖➖ More recent procurements have been from China in the form of the Harbin Y-12 II turboprop transports were delivered in September 1995, one crashed in April 1996.
