What is the definition of "preventive maintenance" as outlined in Technical Manual 12A?

• A. Maintenance performed only after a failure
• B. A proactive approach to prevent equipment failure
• C. Periodic inspections without maintenance
• D. Minimal maintenance just to meet regulations

Answer: (B)

Preventive maintenance is defined as a proactive approach aimed at preventing equipment failure before it occurs. This involves regular inspections, servicing, and repairs based on a schedule or manufacturer's recommendations rather than waiting for a malfunction or breakdown to happen. The goal of preventive maintenance is to enhance the reliability and lifespan of equipment, reducing downtime and repair costs by addressing potential issues in advance. Regular upkeep, which may include activities like lubrication, adjustments, replacements of worn parts, and system checks, is all part of this strategy. This preventive approach is widely recognized in industrial and technical contexts for its effectiveness in maintaining the smooth operation of machinery and equipment.
