Abstract: Large transport aircraft have thousands of provisions of the certification basis and tens of thousands of compliance evidence items, all of which need to be traceable. By reviewing the data characteristics of these provisions, this paper proposes a technical path for constructing a structured type certification basis model, so as to achieve standardized management and control of the provisions. Firstly, the provisions of the certification basis are decomposed level by level based on the hierarchical architecture of review tasks. Secondly, a precise mapping relationship is established between the provisions of the certification basis and compliance verification data. Finally, a full-chain traceable certification basis data network is formed, realizing closed-loop monitoring of the whole life cycle of the type certification basis. This technology effectively solves management problems such as weak data correlation and the difficulty of tracing after the closure of the provisions, among others. It has been successfully applied to a domestic type certification project, where it enables multi-dimensional visual tracking of the provisions of the certification basis. The tracking efficiency is increased nearly fivefold, and management effectiveness is significantly enhanced. Abundant empirical data have also been accumulated for subsequent type certification.
