Under FAR Part 91, what is the pilot's responsibility regarding pre-flight actions?

Under Federal Aviation Regulations (FAR) Part 91, the pilot is directly responsible for determining that the aircraft is airworthy, meaning it is safe for flight, by complying with regulations. Specifically, FAR 91.103 outlines the preflight action required. Each pilot must become familiar with all available information concerning that flight. This includes, as a minimum, reviewing available weather reports and forecasts, fuel requirements, alternatives available if the planned flight cannot be completed, and any known traffic delays. For any flight, pilots must also familiarize themselves with runway lengths at airports of intended use, and takeoff and landing distance information. Finally, they must ensure that the aircraft is airworthy by reviewing the aircraft's maintenance records and conducting a preflight inspection as specified in the aircraft's operating handbook or checklist. This inspection includes checking the aircraft's systems and components to ensure they are functioning properly, and identifying any discrepancies or defects that could affect flight safety. These actions ensure the pilot has sufficient information and the aircraft is in safe condition for the intended flight.
