Aircraft MRO / Line Maintenance installations at Hamad International Airport (DOH)

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.

Hamad International is what happens when a state airline designs its own cathedral. Opened in 2014 and already expanded twice, it serves as Qatar Airways' global spine and routinely tops Skytrax's best-airport rankings. 2024 traffic hit 52.7 million passengers and cargo cleared 2.6 million tonnes — both records. Phase C, now in tender, will lift capacity beyond 70 mppa and add a second passenger processing hall.
