Which type of maintenance focuses on restoring equipment to operational status after a failure?

The type of maintenance that focuses on restoring equipment to operational status after a failure is known as corrective maintenance. This approach is reactive in nature, meaning that it occurs after a malfunction or breakdown has happened. The primary goal of corrective maintenance is to address issues and repair the equipment so that it can return to functioning condition.

In the context of maintenance strategies, corrective maintenance is critical for minimizing downtime that can occur when machinery fails. This approach ensures that when unexpected problems arise, there are processes in place to quickly identify the issue, implement repairs, and restore equipment to its operational state.

On the other hand, preventive maintenance involves regular, scheduled activities designed to prevent equipment failures before they occur. Planned maintenance refers to maintenance tasks that are scheduled ahead of time, and scheduled maintenance generally follows a timetable for conducting routine checks and tasks based on predicted wear and usage. While all these types of maintenance are essential for managing equipment and minimizing unplanned downtime, they do not specifically focus on post-failure restoration like corrective maintenance does.
