摘要：Civil aircraft is a kind of complicated product with the tremendous product data and intricate data evolution process. Data consistency management in the product lifecycle is an extremely significant problem especially for the civil aircraft product. Product data consistency management for civil aircraft is not only required by the airworthiness certification on product conformity inspection, also related to the success of the new product development. On the product data consistency management, there are many researches which focus and discuss on the structure of BOM data, BOM data maintenance method, but few study on the technique of multi-BOM data consistency inspection method. In this paper, the aircraft product BOM layer and structure are analyzed in the "airframer-suppliers" development model, operations and changes during the BOM transition and reconstruction from engineering BOM to manufacturing BOM are illustrated. The differences between engineering BOM and manufacturing BOM which are generated during the BOM transition are classified into �normal inconsistencies� and �erroneous inconsistencies�. For the erroneous inconsistencies inspection, a product structure relation based conformity inspection method is proposed. The corresponding algorithm is clarified, and its workflow is described in detail. The civil aircraft conformity inspection system is developed. The method and system are applied in practical product data management of ARJ21-700 and verified efficiently.
