Another C919 large passenger aircraft, number 104, completed its first test flight in Shanghai on Thursday.
Produced by the Commercial Aircraft Corporation of China (COMAC), the plane took off from a runway at Shanghai Pudong International Airport at 5:32 a.m. After completing various tests, it returned to the airport at 6:57 a.m.
COMAC has carried out test flights on four C919 aircraft so far, with tests of the first three carried out at airports in Xi’an, Dongying and Nanchang.
The successful maiden flight of the C919, China's first self-developed trunk jetliner, took place on May 5, 2017, at Shanghai Pudong International Airport. COMAC plans to run test flights of two more aircraft, the 105 and 106, later in the year.
