Which inspection is performed just before flight?

The end-of-runway (EOR) inspection is conducted just before flight, primarily to ensure the aircraft is in a condition suitable for takeoff. This inspection takes place at the runway threshold and includes checking critical aspects of the aircraft that could affect its performance upon departure. The main goal of the EOR inspection is to identify any issues that may not have been caught during previous inspections and to ensure that the aircraft is functioning correctly in the immediate preflight phase.

In contrast, the other inspections listed serve different purposes. A home station check is a more comprehensive maintenance evaluation that occurs at the aircraft's home base and is not specific to the preflight phase. The thruflight inspection typically takes place between flights but isn’t the direct preflight check. Lastly, a basic postflight inspection is conducted after a flight to look for any discrepancies or faults that need addressing, which makes it unrelated to the preflight procedure. Therefore, the EOR inspection is uniquely positioned in the preflight timeline and focused on ensuring readiness for takeoff.
