52: Troubleshooting/Corrective Action Issue
Definition/Typical Issues
Was the problem misdiagnosed? Was the wrong problem corrected because the troubleshooting was insufficient?
Note 1: Corrective maintenance deals with failures that have already occurred and impending failures that have been identified by other maintenance types. When the other maintenance tasks identify the need for corrective maintenance to repair or restore a component to service, the corrective maintenance activity is addressed by the Corrective Maintenance Issue (#51, #52, #53) nodes.
Examples
Example 1
- Mechanics' job performance was judged by how many work requests they completed. As a result, they tried to diagnose the problem as quickly as possible. This led to rework when the original repairs failed to correct the problem.
Example 2
- The electricians were attempting to locate a short in a feeder circuit. They thought they had isolated the problem to a portion of the circuit, but they were mistaken. They had misread the electrical diagrams and misinterpreted their instrument readings.
Typical Recommendations
- Provide troubleshooting guides based on equipment failure analyses for diagnosis of failed components.
- Provide guidance for resolving typical failures that occur.
- Provide training for personnel on troubleshooting processes.
- Perform post-maintenance testing to ensure that the maintenance is properly performed and corrects the problem.
