Which is NOT a type of maintenance?

• A. Corrective
• B. Preventative
• C. Flexible
• D. Emergent

Answer: (C)

Maintenance types describe when and why maintenance is performed. Corrective maintenance fixes faults after a failure. Preventive maintenance is scheduled tasks aimed at preventing failures. Emergent maintenance (often called emergency or unplanned maintenance) covers urgent issues that arise outside the regular schedule. Flexible, however, is not a standard maintenance category; it describes adaptability or the ability to adjust plans, rather than a defined type of maintenance. Because of that, flexible is not a recognized type of maintenance in these classifications, making it the best choice for NOT a type of maintenance.
