Certified Maintenance & Reliability Professional (CMRP) Practice Exam

Corrective Maintenance (CM) is defined as:

1. Preventive actions taken regularly

2. Repair actions after functional failure

3. Scheduled repairs in advance

4. New installations of equipment

The correct answer is: Repair actions after functional failure

Corrective Maintenance (CM) is fundamentally characterized by actions taken to repair equipment after it has failed to perform its intended function. This approach focuses on diagnosing and addressing the immediate issues caused by a malfunction, thereby restoring the equipment to operational status. The essence of CM lies in its reactive nature; it is undertaken in response to an event rather than as part of a scheduled maintenance strategy. In contrast, other choices depict different maintenance strategies that do not align with the reactive aspect of corrective maintenance. Preventive actions taken regularly are representative of preventive maintenance, which aims to reduce the likelihood of failure through routine checks and service. Scheduled repairs in advance reflect a planned maintenance approach, where tasks are performed based on predetermined schedules regardless of the actual condition of the equipment. Meanwhile, new installations of equipment fall outside the realm of maintenance entirely, as they pertain to the initial setup rather than the upkeep of existing assets. In this context, focusing on the definition of corrective maintenance underscores its role in maintaining the reliability and functionality of equipment after specific incidents occur, ensuring that systems remain operational and continue to meet performance standards.
