What is the primary responsibility of the owner/operator regarding aircraft maintenance?

The primary responsibility of the owner/operator regarding aircraft maintenance is to maintain the aircraft in an airworthy condition. This duty encompasses ensuring that the aircraft meets all safety standards and is operationally ready for flight. An airworthy condition means that the aircraft is free from any defects that could impair its safety or performance. This responsibility is crucial because it directly affects the safety of the flight, crew, passengers, and the public.

While other responsibilities, such as training crew members or managing flight schedules, are important aspects of aircraft operations, they do not directly pertain to the maintenance and safety of the aircraft itself. Regularly checking fuel levels is also a critical operational task, but it is part of pre-flight procedures rather than ongoing maintenance. The owner/operator must prioritize maintaining the aircraft to ensure compliance with regulatory standards and the safe operation of the aircraft in the aviation environment.
