Abstract: Using the reliability engineering theory and methodology, the theoretical, practical;and managerial achievement and experience on the useful life study of airborne equipment are summarized . It is concluded that the key elements of the achievement attained on the durability of airborne equipment in China are the change of the concept of usefullife, development of on applicable evaluationmethod, and establishment of aproper failure criterion. In this paper, four methods of life evaluation and extension are discussed and successful experience of reliability management is summarized. All the mentioned content embodies the features of studying the useful life of airborne equipment in China.
