Development was started by Northwest Polytechnic University in 1965, but was transferred to the Nanjing Aviation Institute.  Two prototypes and a static test article were made.  The first flight of the Yan'an-2 was on 4 September, 1975; alas, the helicopter never reached mass production.  A variant was developed in 1983 in which the main rotor material was changed from metal to composite.

 

A two-seater light helicopter, the Yan'an-2 fuselage was a semi-monocoque pod-and-boom construction on tricycle landing gear.

 

The aircraft never went into production.
