FMEA(Failure Mode and Effects Analysis) is a systematic method of identifying and preventing system, product and process problems. As a standard document, FMEA is produced during the design of products or systems. However, FMEA documentation is rarely validated or updated in practice after it was generated. FMEA validation remains a challenge. In this technical report, we propose to validate FMEA using historical operation and maintenance data. First, we need to verify linkages between FMEA and corresponding operational and maintenance data. Based on statistical results obtained from historic operational data, we update useful FMEA parameters such as Failure Rate and Failure Mode Probability. The updated FMEA can provide more reliable information that could benefit the decision-making process and making maintenance a more efficient practice. The paper briefs the initial investigation and some preliminary results from APU FMEA case study
