民机结构维修中的抽样检查是保证飞机持续适航的关键措施。结构抽样检查是为了掌握同一时期下线飞机的结构损伤情况,以便更好地修订维修计划。针对民机结构维修的抽样是非随机抽样的特点,本文研究了结构维修抽样的原则,结合空客A320抽样经验,给出了我国自主设计大飞机结构维修抽样准则和抽样的具体步骤。
Civil aircraft structural maintenance in the sampling inspection is to ensure continued airworthiness of the aircraft key measures. The structural sampling inspection is to grasp the structural damage of the off-line aircraft in the same period in order to better revise the maintenance plan. In this paper, the principle of structural maintenance sampling is researched. Combining with the experience of Airbus A320 sampling, this paper gives the concrete steps of designing sampling guidelines and sampling for structural maintenance of autonomous large-scale aircraft in our country.
