This is the case of Breakdown Maintenance

What is breakdown maintenance?

Breakdown maintenance is maintenance performed on a piece of equipment that has broken down, faulted, or otherwise cannot be operated. The goal of breakdown maintenance is to fix something that has malfunctioned. To the contrary, preventive maintenance is performed in order to keep something running.

Sometimes breakdown maintenance is performed because of an unplanned event. For example, if a critical piece of machinery breaks, the maintenance is performed because of the imminent need for that machine to operate again. However, breakdown maintenance can be planned for in advance, which is what we might call “good” breakdown maintenance.

1) Planned Breakdown Maintenance

2) Unplanned Breakdown Maintenance
