The Harbin Y-12 is a high wing twin-engine turboprop utility aircraft built by Harbin Aircraft Manufacturing Corporation (HAMC).

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, a larger fuselage and bonded rather than riveted construction.

The first prototype flew on 14 July 1982, followed by about 30 production T-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 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.
