Y-11

The Harbin Y-11 is a Chinese short-range STOL light transport aircraft designed in the early 1970s as a replacement for the Shijiazhuang Y-5 and entered service in the late 1970's. The Y-11 is powered by two Teledyne Continental TSIO-550-B flat-six piston engines providing a top speed of 265 kmh and a range of 300 km fully laden. The Y-11 carries a crew of one or two and up to seven passengers or 900 kg of freight, normally though 1200 kg of freight can be carried under restricted conditions.
