    Abstract:

    At present, the main manufacturers of civil aircraft in China often use empirical judgment to make repair level decisions for structural components, especially with limited decision-making experience in workshop repairs. Therefore, there is an urgent need to conduct research on repair level analysis technology. Level of repair analysis is not only one of the important links in the logistics support analysis of civil aircraft components, but also an important input for the planning and preparation of component maintenance manuals. Most international mainstream civil aircraft manufacturers have begun to adopt the S3000L standard for logistics support analysis. This article studies the Level of Repair Analysis (LORA) method provided in the S3000L standard, and combined with the experience of continuous airworthiness document organization to develop a repair level analysis process suitable for civil aircraft structural components. Practical examples are also used for feasibility verification. The research results indicate that using non-economic simplified LORA analysis method for structural components is more feasible at present. The analysis process provided in this article can provide reference for domestic main manufacturers to develop structural component maintenance manuals.
