Conducting an annual elevator inspection is an example of ___.

• A. Scheduled maintenance
• B. Vibration analysis
• C. Scheduled shutdown
• D. Predictive maintenance

Answer: (D)

The main idea is about maintenance that is planned on a set schedule to keep equipment safe and compliant. An annual elevator inspection is a routine, calendar-driven task performed to meet safety and regulatory requirements, regardless of the equipment’s current condition. That makes it scheduled maintenance. It isn’t based on monitoring data to predict when a component will fail, which is what predictive maintenance would involve. Predictive maintenance uses condition indicators (like vibration, wear, or other data) to time repairs or replacements before failure. It also isn’t a planned shutdown for production or a temporary outage; those are different kinds of maintenance events. So the best fit is scheduled maintenance.
