The cylinder controlled Y-11 and turboprop Y-12 are Chinese created provincial aerial transports and utility transports.

Outline of the Type 11 Transport Aircraft, or Yunshuji 11 (Y-11) started amid the mid 1970s as a swap for the Antonov A 2 utility biplane in Chinese administration (permit implicit China as the Y-5). A model was constructed and flown at Shenyang in 1975, while preseries and creation airplane are fabricated at what is currently the Harbin Aircraft Manufacturing Company. Creation Y-11s were manufactured from 1980. Peculiarities incorporate two outspread motors, capacity for harsh field operations and STOL execution. Y-11s have seen benefit as suburbanite aerial shuttles and have likewise been arranged and utilized for ag splashing.

The Y-11b is an enhanced improvement controlled by Teledyne Continental motors to overcome single motor elevation execution deficiencies. The primary Y-11b's lady flight was on December 25 1990.

The Y-12 is a turboprop controlled improvement and has been inherent more noteworthy numbers than the Y-11. Chip away at a turboprop fueled Y-11 started in the early 1980s, and a Pratt & Whitney Canada Pt6a controlled and amplified lodge Y-12 model (long ago the Y-11t) flew surprisingly on August 16 1984. Current creation is of the Y-12-II, while the further enhanced Y-12-IV was conceded US certificate in March 1995.

Canadian Aerospace Group (CAG) and its Panda Aircraft Company subsidiary offers a created Y-12 as the Twin Panda, which it goes for the twin Otter substitution market. The Twin Panda is focused around the Y-12-IV yet offers all the more effective Pt6a-34 motors, reinforced arriving rigging, and updated flying and inner part. Creation Twin Pandas will be implicit China and equipped in Canada preceding conveyance. In 2000 Canadian Aerospace bunch said it had requests for 35 Twin Pandas.
