Line maintenance is the routine, day-to-day servicing and minor repairs of aircraft to ensure they’re ready for safe and efficient operations. This work is typically performed at the airport gate or hangar between flights. Line maintenance tasks include pre-flight and post-flight inspections, troubleshooting, fluid refills, tire changes, and minor repairs. It’s designed to identify and address any immediate issues that could affect safety, allowing the aircraft to continue its scheduled flights without delay. Line maintenance requires quick problem-solving skills and a thorough understanding of aircraft systems.
