Comac has started low-speed taxi tests with the second prototype of the C919 aircraft.
Flight Test Aircraft two (FTA-2) completed nine test points, says Comac in a brief statement. The work took place at Shanghai Pudong International airport, which is adjacent to the Comac production facility.
The work comes one month after Comac successfully powered up the CFM International Leap-1C engines on the aircraft.
The first C919 prototype flew to Xian on 10 November, where the next phase of flight tests and certification work will take place.
Comac will use six test aircraft and conduct flight tests across sites in Shanghai, Xian, and Dongying. It aims for the second prototype to make its first flight before the end of 2017.
It hopes to obtain certification and certification in 2020-2021. The C919 has 730 commitments from 27 customers.
