Corrective maintenance is the type of maintenance performed to repair or correct faults, breakdowns, or damage to equipment, machinery, or systems once they have occurred.

Its main objective is to restore normal equipment functionality quickly and efficiently, minimizing downtime. This type of maintenance can be planned, in the case of previously detected failures, or unplanned, when the failure occurs unexpectedly.

It is generally reactive and is performed in response to unforeseen problems, and is essential to ensuring operational continuity and system security.
