Who is responsible for ensuring that a maintenance manual is properly carried aboard a supplemental air carrier?

• A. The pilot-in-command
• B. The maintenance staff at the carrier
• C. The ground operations manager
• D. The regulatory compliance officer

Answer: (A)

The pilot-in-command holds ultimate responsibility for the safety and operation of the aircraft, which includes ensuring that all necessary and required documents, such as maintenance manuals, are onboard. This is a critical aspect of their duties, as the pilot-in-command must have access to the information necessary to address any technical issues that may arise during flight operations. The maintenance manual provides essential guidelines for aircraft maintenance, troubleshooting, and repair procedures, which the pilot might need to reference, especially in case of an in-flight emergency.

While the maintenance staff, ground operations manager, and regulatory compliance officer may play roles in the maintenance and operational readiness of the aircraft, it is the pilot-in-command who has the final authority and responsibility for ensuring that all required documentation is on board before flight. This duty is rooted in aviation regulations and best practices that prioritize flight safety and accountability, reinforcing the importance of having the correct materials readily available at all times.
