Hafei Aviation Industry Y12
Developed from the earlier piston-engined Y-11, the twin-PT-6A-powered Y-12 has an enlarged cabin to accommodate up to 17 passengers. A first production batch of 18 aircraft was scheduled for completion by the end of 1986.
The Y-12 prototype first flew in 1982, and there have been three series production versions
Initial version with 500 shp PT6A-11 engines, 93” diameter propellers,
leading edge slats, seating for 17 passengers and a MTOW of 5000 kg.
Later production version with higher-rated 600 shp PT6A-27 engines, plain leading edge, 98” diameter propellers and MTOW increased to 5300 kg. The UK CAA issued Type Certificate FA49 for this variant in 1990 and examples are in operation in Malaysia and Fiji.
Improved model with sweptback wingtips, redesigned seating for 18-19 passengers and max. weight increased to 5700 kg. The Canadian Aerospace Corporation markets a version of the aircraft under the Twin Panda name as a DHC-6 replacement.
The Sri Lankan Air Force ordered six Y-12 turboprop utility transports from China in 1986, and at least two have been delivered to the Chinese Air Force for aerial survey work.
The Y12 was originally produced by Harbin Aircraft Manufacturing Corporation (HAMC), and under Chinese commercial arrangements is marketed by the China Aviation Technology Import and Export Company (CATIC). HAMC has subsequently been reorganised in 1999 as Hafei Aviation Industry Co. Ltd (HAI), responsible for the Y12 and other sub-contract work.
