What must pilots ensure regarding aircraft maintenance?

• A. Preflight checks
• B. Scheduled inspections, servicing, and maintenance of the aircraft, including preflight checks
• C. No checks are required
• D. Maintenance must be performed by authorized personnel after every flight

Answer: (D)

Keeping an aircraft airworthy relies on maintenance being done by people who are authorized and trained for it. Pilots must ensure that the aircraft has been serviced and repaired by qualified maintenance personnel and that the work is properly documented before the next flight. This protects against undetected faults and ensures the aircraft meets all safety and regulatory standards.

Pilot responsibilities include performing necessary preflight and postflight checks to verify there are no obvious issues, but routine maintenance, inspections, servicing, and repairs must be carried out by authorized personnel. That’s why maintenance performed after every flight should be done by those qualified to do it.
