The Thruflight Inspection requirements are accomplished as a turnaround inspection prior to takeoff on the ______ on selected types of aircraft.

• A. First flight of the day
• B. Second and each subsequent flight of the day
• C. Last flight of the day
• D. During routine maintenance

Answer: (B)

Thruflight is a turnaround, pre-takeoff external check done between flights on certain aircraft types to verify there are no obvious issues carried over from the just-completed leg. It is performed before the second flight of the day and again before every subsequent flight, ensuring any new damage, leaks, or loose items spotted after the previous flight are addressed before departure. It wouldn’t be done before the very first flight of the day since there’s no prior leg to review, and it isn’t a routine maintenance task or limited to the last flight.
