Which maintenance type is performed on the basis of hours, cycles, or calendar/mileage?

• A. Unscheduled Maintenance
• B. Daily inspections
• C. Scheduled Maintenance
• D. Rework

Answer: (C)

Scheduled maintenance is maintenance performed on a planned schedule based on hours of operation, cycles, or calendar/mileage. This approach uses predefined intervals so service occurs before wear leads to failure, improving reliability and uptime. For assets, you might schedule service every certain number of hours, after a specific number of cycles, or on a calendar date or mileage threshold. This contrasts with unscheduled maintenance, which happens after a problem arises; daily inspections are routine checks but aren’t necessarily tied to a formal interval; and rework involves fixing defects after production rather than performing planned servicing.
