The responsibility for ensuring that an aircraft is maintained in an airworthy condition is primarily that of the:

• A. Owner or operator of the aircraft
• B. Pilot in command
• C. Mechanic who performed the maintenance
• D. The manufacturer

Answer: (A)

The key idea is that airworthiness is a responsibility assigned to the aircraft’s owner or operator. They must ensure the aircraft is maintained according to the approved maintenance program, have inspections completed on schedule, maintain proper records, and arrange for any necessary repairs before flight. The pilot in command must verify the aircraft is safe to fly and not fly if there are known airworthiness issues, but the overarching duty to keep the aircraft in an airworthy condition rests with the owner or operator. The mechanic’s role is to perform maintenance correctly and document it, while the manufacturer provides the design and service information, not the day-to-day responsibility for ongoing airworthiness.
