China's C919 passenger jet completes all the test flights

China's domestically developed single-aisle C919 passenger jet has undergone all the test flights for obtaining an airworthiness certificate in the country, its manufacturer Commercial Aircraft Corp of China said.

The first C919 narrow-body passenger jet is expected to be delivered to China Eastern Airlines, its debut customer, before the end of this year. Six C919 prototypes underwent a series of hard tests.

The manufacturer said the completion of all the tasks of test flights indicates that the preparation work before getting the certificate has officially entered the final stage.

So far, 815 intended and confirmed orders have been placed for the C919 from home and abroad.  The aircraft model's competitors include single-aisle B737 of Boeing and A320 of Airbus.
