What does "on-condition" maintenance primarily involve?

"On-condition" maintenance primarily involves monitoring the performance of equipment and determining when maintenance is necessary based on actual conditions and performance metrics. This approach focuses on the ongoing assessment of a component's functionality, allowing for maintenance actions to be taken only when specific indicators show that serviceability is at risk.

This method contrasts with maintenance practices that operate on fixed schedules or based solely on the passage of time, such as scheduled maintenance or age-based component replacement. By relying on real-time data and performance analytics, "on-condition" maintenance fosters a more efficient use of resources, minimizing unnecessary maintenance activities and extending the lifecycle of components. It prioritizes the operational readiness and reliability of equipment, which is particularly valuable in settings where performance is critical, such as in aviation and heavy machinery management.
