During PMCS, if a component is found damaged, what is the correct action?

• A. Continue work and substitute a different part without notification.
• B. Return equipment to service and schedule a replacement later.
• C. Attempt temporary repair and log as complete.
• D. Stop work, document, replace with correct part, and verify root cause.

Answer: (D)

The action this item tests centers on safety and proper maintenance discipline: when a component is found damaged during PMCS, you must stop work, document the discrepancy, replace it with the correct part, and then verify the root cause before putting the equipment back into service. This approach creates an auditable maintenance record, ensures the system remains within spec, and addresses the underlying issue so it doesn’t recur. Pushing on with a substitute part, attempting a temporary repair and declaring the work complete, or returning equipment to service without addressing the damage all mask problems, increase safety risk, and can lead to unexpected failures. Properly stopping, logging, replacing with the correct part, and investigating the cause protects personnel and maintains readiness.
