Harbin Y-12

https://en.wikipedia.org/wiki/Harbin_Y-12

The Harbin Y-12 is a high wing twin-engine turboprop utility aircraft built by
Harbin Aircraft Industry Group (HAIG).

The Y-12 started as a development of the Harbin Y-11 airframe called Y-11T in
1980. The design featured numerous improvements including a redesigned wing with
a new low drag section, a larger fuselage and bonded rather than riveted
construction.

The first prototype, followed by about 30 production Y-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 power plants are two Pratt & Whitney Canada PT6A-27 turboprops with
Hartzell propellers. The Y-12 has a maximum takeoff weight of 5,700 kg (12,600
lb) with seating for 17 passengers and two crew. The aircraft is operated as a
light commuter and transport aircraft.

The latest development is Y-12F, which is almost a new design with many
improvements: new wings, new landing gears, new fuselage, with more powerful
engines from Pratt & Whitney Canada and extended payload and range. The Y-12F
made its maiden flight on December 29, 2010, received the CAAC type
certification on December 10, 2015, and the FAA type certification on February
22, 2016. In 2015 Kenmore Air announced that they would begin development of
floats for the Y-12 for FAA certification. The Y-12 completed the FAA
evaluation flight tests for its automatic flight control system on June 30,
2018, with its performance meeting the requirements, said AVIC Harbin Aircraft
Industry Company Ltd (AVIC HAFEI).
