Line Maintenance & AOG Line Stations
Line maintenance is the lightest tier of the MRO hierarchy, performed at the gate or on the apron between flights: daily and pre-flight checks, transit checks, defect rectification, fluid servicing and scheduled A-checks. Providers run permanent or roaming line stations under EASA Part-145, FAA 145 or GCAA CAR-145 line scope, with type ratings matched to the carriers transiting that field. The cluster also covers Aircraft-on-Ground (AOG) line response — rapid mobile teams and 24/7 desks that recover grounded aircraft. Buyers are airline technical departments choosing transit-station coverage, and ground handlers or hub MROs selling third-party line support across their network.
"Dubai (DXB/DWC), Abu Dhabi, Doha and the Saudi hubs are among the world's busiest wide-body transit points, so reliable line coverage and fast AOG turnarounds directly protect on-time performance for Emirates, Qatar, Etihad, Saudia, flydubai and Riyadh Air. Lufthansa Technik already runs a Sharjah/Dubai line and AOG node, and carriers increasingly buy third-party line support at fields outside their home base across the GCC and wider MENA."
