China's first domestically-developed regional ARJ21 jet made its longest trial flight of 1,300 kilometers in about two hours from Shanghai to Xi'an, capital of northwestern China's Shaanxi Province, on Wednesday.

The jet moved from its production site in Shanghai to the Xi'an-based Chinese Flight Tests Establishment (CFTE) of the Aviation Industry Corporation of China (AVIC), the country's only institute qualified to issue flight certificates for military aircraft, helicopters, aircraft engines or other aircraft equipment.

The jet is expected to make further trial flights before gaining approval certificates from the CFTE. The jet made its first trial flight in November 2008.
