Airworthiness Engineering and Practices of COMAC C919 Airplane

This paper systematically summarizes that COMAC follows the basic philosophy and principles of airworthiness in the process of developing C919 large passenger aircraft, carries out type certification along with the aircraft development process, and plans and implements compliance activities for airplane design features. On the basis of ensuring that airplane product meets airworthiness requirements, COMAC has also established an airworthiness management system, including design assurance system and continuing airworthiness system, to ensure that aircraft are designed in accordance with airworthiness requirements, to show compliance with airworthiness requirements and to continuously ensure the airworthiness of airplane by dealing with continuing airworthiness events in service.
