Which statement defines Conditional maintenance?

Which statement defines Conditional maintenance?

• A. Any servicing or replacing of parts required because a component is no longer serviceable or has failed.
• B. Maintenance performed during production downtime.
• C. Maintenance performed on an as-needed basis only.
• D. Maintenance that is performed on a monthly schedule.

Answer: (A)

Conditional maintenance is maintenance that is performed when the equipment’s condition indicates it’s needed. It’s driven by evidence of wear, degradation, or failure rather than by a fixed date or downtime. The statement that describes servicing or replacing parts because a component is no longer serviceable or has failed reflects this approach: action is taken due to the component’s condition. The other options describe schedule-based timing (downtime or monthly) or vague as-needed timing, which aren’t driven by the actual condition of the component.
