Corrective maintenance when a fault occurs includes which of the following activities?

• A. Preventive Maintenance
• B. Predictive Maintenance
• C. Breakdown Maintenance (Corrective actions)
• D. Proactive Maintenance

Answer: (C)

When a fault occurs, corrective maintenance focuses on restoring equipment to operating condition through repair or replacement of the failed parts. The activities you typically perform include diagnosing the fault, repairing or replacing defective components, reassembling or recalibrating as needed, and testing to ensure the system runs again. This approach is commonly referred to as breakdown maintenance because the work happens in response to a failure, with the goal of returning the equipment to service as quickly as possible.

This differs from preventive maintenance, which is planned and performed before any fault to prevent failures; predictive maintenance, which uses condition data to predict and plan ahead; and proactive maintenance, which tackles underlying causes to prevent recurrence. The scenario described aligns with breakdown maintenance since the focus is on actions taken after a fault to repair and restore function.
