Aircraft MRO / Line Maintenance

MRO covers the full maintenance hierarchy: line (daily, transit, A-check) at the apron, base maintenance (C-check and D-check) in hangars, engine shop visits, component repair and overhaul, painting and cabin reconfiguration. Providers hold multiple national approvals (EASA, FAA, GCAA, GACA, QCAA) and type ratings for Airbus, Boeing, Embraer and increasingly COMAC. Airlines either run captive MRO (Emirates Engineering, Qatar Airways Technical, Etihad Engineering) or outsource to third parties; the Gulf is pivoting to become a net exporter of MRO capacity.
