What type of maintenance is performed in response to reported defects?

Corrective maintenance is the type of maintenance that is specifically performed in response to reported defects or failures. When defects are identified, the primary goal of corrective maintenance is to identify the issue, determine the necessary actions to restore the system or equipment to its proper functioning state, and perform those repairs.

This approach addresses problems as they occur, making it reactive in nature. It is essential for ensuring operational readiness, as it directly fixes problems that could hinder functionality. This ensures that equipment can be used safely and effectively after the repairs have been made.

In contrast, routine maintenance involves scheduled inspections and services that prevent potential issues but do not specifically address reported defects. Preventive maintenance is composed of proactive measures taken to avoid faults, while predictive maintenance uses data analysis to predict when maintenance should be performed to prevent failures before they occur. Thus, these types do not directly respond to existing defects as corrective maintenance does.
