What is the difference between preventive maintenance and corrective maintenance in aviation?

• A. Preventive is scheduled inspections to prevent failures.
• B. Preventive is unplanned maintenance to fix failures.
• C. They are the same.
• D. Corrective is scheduled inspections to prevent failures.

Answer: (A)

Preventive maintenance is a proactive, scheduled effort to keep an aircraft airworthy by inspecting, servicing, and replacing components before they fail. The goal is to catch wear and degradation early, so problems don’t show up during flight. Corrective maintenance is unplanned work that happens after a fault or failure is detected, aimed at restoring the system to working condition. Because preventive maintenance involves planned inspections at defined intervals to prevent failures, that description best fits the concept. The other options describe unplanned work as preventive, or swap the ideas of scheduled inspections and maintenance roles, which isn’t accurate.
