The Commercial Aircraft Corporation of China (Comac) announced on Saturday that the test flight programme for its C919 single-aisle airliner had been completed. This was the final step before the aircraft could be certified by China’s aviation regulators. The programme involved six test examples of the C919. The first production example for a customer airline made its maiden flight in May. That airline is C919 launch customer, China Eastern Airlines, which has placed firm orders for five of the new airliners. According to its website, Comac currently has orders for 815 C919s from 28 customers. However, leading aerospace journal FlightGlobal reports that Comac currently has “commitments” for more than 300 of the airliners.
