In this article, the Process Fault Tree Analysis (PFTA) method is researched, which is about to the risk management of spacecraft Assembly Integration and Test (AIT) process. The method of how to identify the top event and bottom event of Spacecraft AIT process risk and the method of how to assess the risk severity of the bottom event is introduced. The model of risk control matrix is established. From the responsibilities, tools, methods, monitor and other dimensions about the post roles involved of the AIT process, how to establish a risk management system based on the identification, assessment, analysis and control of the whole AIT process is researched. In this risk management system, through technology subject, quantitative topic, process improve, Quality Control (QC) subjects, implementation of product assurance elements, writing Standard Operating procedure (SOP), maintaining system documents, combing knowledge and operation taboo items and other method is used.
