The Sino-Russian joint CR929 wide-body aircraft project has issued a request for proposal (RFP) for its landing gear system, the Commercial Aircraft Corporation of China (COMAC) said on Friday.

Commercial Aircraft International Co. Ltd. (CRAIC), a joint venture between COMAC and its Russian partner United Aircraft Corp., has issued the RFP to potential suppliers worldwide, according to COMAC.

The RFP includes all major requirements for the full life cycle of CR929's landing gear system, including engineering, customer service, quality, airworthiness and supply chain management.

The supplier of the landing gear system will be listed among the first-tier suppliers, as the system requires extremely high safety standards and its development involves a long and complicated process of design, manufacturing, and testing.

All potential suppliers are requested to submit their proposals by the end of November.

In May 2017, the CRAIC was set up to develop the CR929, a 280-seat widebody jetliner with a range of 12,000 km. Its preliminary design is expected to be concluded in mid-2019.
