What is the process of repairing or restoring equipment after it has broken called?

The process of repairing or restoring equipment after it has broken is known as corrective maintenance. This term encompasses activities aimed at fixing defects or failures in equipment or systems, ensuring they return to an operational state. Corrective maintenance is essential in various fields, including military operations, where maintaining equipment functionality is critical for mission success.

Contingency refers to a plan or provision made for future circumstances, often involving preparations for unexpected events, rather than the act of repairing equipment. Contribution generally pertains to the act of providing something, such as resources or support, and is not related to the maintenance process. A contract is a legally binding agreement between parties and does not specifically reference the process of repairing or restoring equipment. Thus, corrective maintenance is the most accurate term, as it directly describes the objective of restoring equipment functionality after a breakdown.
