Functional Failure Analysis (F-F-E-C) |
If an item in the system hierarchy has been identified as a Maintenance Significant Item (MSI), or if it is eligible to be identified as an MSI, the F-F-E-C tab will be displayed in the Analysis panel. You will use this tab to perform the functional failure analysis (i.e., record the functions, failures, effects and causes that have been identified for the item), the failure effect categorization and the maintenance task selection. The Failure Effect Categorization (FEC) window (F-F-E-C > Effect > Categorization) presents the logic diagram from the MSG-3 guidelines. The category selected (e.g., Evident Operational, Hidden Safety, etc.) will determine which of the maintenance task selection questions from the MSG-3 guidelines will be enabled in the Tasks Selection window (F-F-E-C > Cause > Tasks Selection). The software includes built-in logic checks to ensure that the maintenance tasks defined to address each potential failure mode are compliant with the analysis team's answers for the FEC and Maintenance Task Selection logic. |
