history
The Y-12 was developed as the successor to the Harbin Y-11 since 1980 . In relation to this, it has a greater range and modified wings. The first machine took off on July 14, 1982 on its maiden flight. The type was used by Lao Airlines , Air Fiji , Air Kiribati , Air Vanuatu as well as various Asian and African armed forces and the Peruvian Air Force . Around 200 Y-12s had been built by March 2016.
In mid-November 2014, rumors circulated about a sale of 20 pieces to an American company. However, it wasn't until 2016 that Version E received its type certification in the USA.
Various countries received the aircraft as a gift from China, for example the aircraft in use at Real Tonga , where a Chinese Xian MA-60 had also been given away.
Versions
The improved variants Y-12 II (with PT6A-27 (462 kW) and Hartzell propeller) with approval in 1984 and Y-12 IV followed later .

The Y-12E for 18 passengers (developed on the basis of the Y-12 IV), which is still in use today, uses the improved PT6A-135A, better avionics and interior equipment as well as a modified landing gear. The Y-12E is 14.6 m long, has a wingspan of 19.2 m and a maximum take-off mass of 5.67 tons. The maximum speed is 238 km / h, the range 1340 km, the flight altitude 7000 m.
The Y-12 G is a freighter version for three LD3 standard containers. The Y-12 Twin Panda (2000) is an export version based on the Y-12 II, but it was developed later than the Y-12 IV.
The current version Y-12 F consists of a wider fuselage, new wings, a retractable landing gear and more powerful engines. It is licensed by the Federal Aviation Administration for the United States .
