摘　　要：通过对一起铆钉失效引发飞机发动机空中停车的不安全案例入手,对该机型机群进行普查,进一步发现铆钉失效是典型普发性机械故障。针对该故障,分别从飞机制造设计中铆钉的选用和飞机使用过程中的维护检查标准等方面进行分析,并从飞机设计、使用、维护检查等方面提出安全建议,不断提升飞机结构完整性和安全裕度。Through the unsafe case of in-flight shut-down of aircraft engine failure caused by rivet failure, a general survey of the aircraft cluster is carried out, and it is further found that rivet failure is a typical general mechanical failure.In response to this failure, the selection of rivets in aircraft manufacturing design and maintenance inspection standards during aircraft use are analyzed. Safety recommendations are also made from the aspects of aircraft design, use,maintenance inspection to continuously improve the structural integrity and safety margin of the aircraft.
