What type of maintenance is generally involved in a line or ramp maintenance service?

Line or ramp maintenance services are routine tasks that ensure the aircraft’s airworthiness between flights and typically include minor scheduled or unscheduled maintenance tasks. These tasks often involve inspections, servicing of components, repairs, and minor adjustments to ensure that the aircraft is in optimal condition for its next flight. These maintenance activities are essential for the day-to-day operation of the aircraft and are designed to be completed quickly to minimize downtime.

This type of maintenance contrasts with major scheduled maintenance, which involves extensive work done at longer intervals and often requires the aircraft to be out of service for a significant period. Complete refurbishment and overhaul or engine overhauls are more extensive processes that are not performed during line or ramp maintenance, as they require considerable time and resources beyond what is typically available during quick turnarounds. Therefore, the option that aligns best with the nature of line or ramp maintenance is the minor scheduled or unscheduled maintenance.
