On December 28, China Commercial Aircraft Corporation held the launch event for the Big Plane large-scale series construction project at the final assembly manufacturing center in the Pudong base. As the C919 is about to enter a new phase of large-scale operation, China Commercial Aircraft Corporation will accelerate its own capacity building while further strengthening cooperation with upstream and downstream enterprises in the Industry Chain, relying on the Big Plane project to promote the gathering of more aviation companies and resources in Shanghai, contributing to the transformation of Shanghai's economic structure and economic and social development.
