What ensures the corrective action is validated after its implementation?

• A. Re-check the torque after replacement.
• B. Document the action and stop.
• C. Continue with the inspection schedule.
• D. Confirm that the corrective action resolved the issue and no new issues were introduced.

Answer: (D)

Validating a corrective action means actively confirming that the fix actually solved the problem and didn’t create new issues. After implementing the fix, you verify outcomes by observing system performance, running any necessary tests, and monitoring for recurrence or side effects. This ensures the issue is resolved and the operation remains safe and reliable.

The best choice encapsulates this by stating that you confirm the corrective action resolved the issue and that no new issues were introduced. It goes beyond a single check or documentation alone, focusing on actual effectiveness and unintended consequences.

Narrow checks, like re-checking torque, are important parts of maintenance but don’t prove that the overall corrective action worked. Merely documenting the action or continuing the inspection schedule without a verification step also misses confirming actual resolution and safety.
