S-92 “Heli-Bus” was developed and manufactured by six risk-sharing cooperative partners including Sikorsky Aircraft Corporation, Jingdezhen Helicopter Group (JHG), Aerospace Industrial Development Corporation (AIDC) of Taiwan, Mitsubishi Heavy Industries (MHI) of Japan, Gamesa Corporation of Spain, and Embraer Aviation Industries Corporation of Brazil. Changhe Aircraft is responsible for development and manufacture of tail rotor pylon and horizontal stabilizer.

Since 1995 the development of S92 TRP was launched, and the first TRP was delivered in May 1997. Up to December 15, 1998, the delivery for the first five shipsets of S-92 TRPs was completed according to Sikorsky Aircraft’s requirements both in quality and schedule. Changhe Aircraft was the first partner that finished the delivery of the first five pre-production S-92 prototypes in schedule among six partners, and all tail rotor pylons were successfully joined with tail booms at one time. At present, Changhe Aircraft has possessed capability for series production.
