Harbin Z-5


The Harbin Z-5 is a Chinese variant of the Soviet Mil Mi-4 piston powered helicopter. Before its discontinuation from service, it was produced in Harbin, China.

History

The Soviets provided China with Mi-4 blueprints just a few years before the Sino-Soviet split in 1958; maiden flight was in 1958 and mass production started in the mid-1960s. China has produced a number of unique variants through this model, and the Z-5 was employed by the PLA, PLAAF and PLANAF in large numbers as reserve forces. A total of 558 Z-5 were built. A few Z-5 helicopters were modified to carry machine-guns and rocket pods.
During the Chinese-Western rapprochement, one Z-5 was refitted with a Pratt & Whitney Canada PT6T-6 "Twin Pac" turbo-shaft engine in 1979. Some sources refer to this as the Z-6, but this variant was discontinued after its first model.
