What is defined as corrective maintenance in the 3-M system?

Corrective maintenance in the 3-M system refers to the actions taken to repair equipment that has already failed. This type of maintenance is reactive in nature, occurring after a malfunction or breakdown has been identified. The goal of corrective maintenance is to restore the equipment to operational condition as quickly as possible, minimizing downtime and ensuring that the equipment is functioning as intended.

In the context of the 3-M system, corrective maintenance is distinguished from other forms of maintenance, such as scheduled servicing, which involves routine checks and upkeep performed at predetermined intervals to prevent equipment failure. Preventive measures aim to eliminate the risk of failure before it occurs, while upgrading equipment serves to enhance performance or compliance with new standards. Therefore, understanding that corrective maintenance specifically addresses issues that arise after equipment has ceased performing its intended function is crucial for effective maintenance management.
