The Harbin Y-11 and Y-12 are light transport aircraft in China. They were designed to meet a requirement put out by the Chinese government to serve as a replacement for the Y-5 (Antonov An-2 Colt). The Y-11 and Y12 are essentially the same aircraft, just with different engines. Seeing as there are no more Y-11s in service, and there never were very many, I will simply refer to the project as the Y-12 from here on out. The Y-12 was designed to incorporate STOL performance, as well as be rugged and versatile. The aircraft first flew in 1975, and entered production a year later. The aircraft now serves as a utility STOL transport in China.
