In the process of the aerospace product development and production, the technology of FMEA has been very common to recognize and analyze the failure mode. However, there are still many misunderstandings in the application of FMEA technology. In this paper, the research concerns the following aspects: the FMEA concept, the FMEA essence, various correspondences of FMEA analysis process, FMEA work form, the relationship between FMEA and other reliability work items. By analyzing the FMEA problem of the aerospace product development and production, we analyze and summarize the solutions against the FMEA work errors to enhance the effectiveness of FMEA technology.
