Which of the following best defines "preventive maintenance"?

• A. Repairing equipment after it breaks down
• B. Scheduled checks to avoid future equipment failures
• C. A process that ignores minor issues until they escalate
• D. Maintenance conducted only when requested by pilots

Answer: (B)

Preventive maintenance is best defined as scheduled checks to avoid future equipment failures. This approach involves regularly scheduled maintenance tasks that are designed to identify and address potential issues before they lead to equipment breakdowns. By proactively servicing equipment, preventive maintenance helps ensure that systems operate reliably and efficiently, reducing the risk of unplanned outages and extending the lifespan of the equipment. This type of maintenance is critical in various fields, including aviation, where reliability and safety are paramount. It contrasts with reactive maintenance strategies, which wait for equipment to fail before any action is taken. Preventive maintenance emphasizes planning and routine inspections, making it a proactive method to enhance operational efficiency and reduce long-term maintenance costs.
