When should Thru-Flight (TH) inspections be performed?

Thru-Flight (TH) inspections are essential routine checks conducted to ensure that an aircraft is safe and ready for operation between flights, especially if it is set to make another flight on the same day. This ensures that any potential issues can be identified and addressed promptly, thereby maintaining safety and operational efficiency.

Such inspections are designed to examine critical systems and components and to confirm that the aircraft remains in compliance with safety standards and regulations. The procedures might include checks on fuel levels, oil levels, and the general condition of the airframe and systems to ensure that everything is functioning as expected.

Conducting TH inspections between flights allows for any necessary adjustments or repairs to be made before the next departure, thus preventing potential safety hazards and ensuring that all operational protocols are met.
