Abstract: The nondestructive testing data of civil aircraft structures directly affect the efficiency and accuracy of the structure damage assessment and repair decision. The construction of a unified data platform is of great significance for the retrieval, sharing, dissemination, storage, and reuse of the structures nondestructive testing data. This paper proposes nondestructive testing data management requirements and functional requirements of the civil aircraft structure, formulates the rules of civil aircraft structure damage data source model and the damage numbering, designs and develops the civil aircraft structure of nondestructive testing data management system, thus leading to the implementation of electronic and network management for the civil aircraft structural damage data and knowledge of nondestructive testing in structure strength test.
