Research on Design Assurance System with the Development of CAAC's Design Organization Management

The development process of design organization management is described for the airworthiness authorities of the United States, Europe and China. Similarities and differences between EASA's DOA and CAAC's DAS are summarized from the regulations and certification styles. In addition, the functions of DAS are analyzed and delineated with detail activities. And an organization structure to implement the airworthiness function of DAS is proposed, which provides a platform to perform duties properly to demonstrate the compliance with airworthiness requirements in the design process. Meanwhile, the status of Chinese civil aviation industry is described and some optimizing actions in the future are proposed.
