The C919's maiden flight has been delayed at least twice since 2014 due to production issues.
China first gave the world a glimpse of the 158-seat plane in November 2015 at a roll-out ceremony in Shanghai.
The aircraft is a symbol of China's ambitions to break into a duopoly enjoyed by Western giants Airbus and Boeing Russia is developing a similar jet.
China Eastern Airlines is the launch customer for the plane, which is powered by engines from French-U.S. supplier CFM International, jointly owned by General Electric and Safran.
