Failure mode, effects and criticality analysis (FMECA) is probably the most widely used and most effective design reliability analysis method. The standard reference is US MIL-STD-1629A (Procedure for Performing a Failure Mode, Effects and Criticality Analysis). The principle of FMECA is consider each failure mode for every components of a system and ascertain the effects on system operation of each failure mode in turn. Failure effects may be considered at more than one level, at subsystem and at overall system level (local and system effect). Failure modes are classified in relation to the severity of their effects. The result of this analysis is FMECA Worksheet. This worksheet contains useful data that represent criticality of certain failure mode to related maintainable item. Based on this worksheet, engineers can improve maintenance to decrease failure rate of certain component effectively.
