Base & Heavy Airframe Maintenance
Base maintenance is the heavy end of the hierarchy: aircraft are taken out of service into a hangar for major scheduled checks (C-check, D-check), structural and composite repair, fuselage and wing inspections, modifications and lease-redelivery checks. It demands large hangar bays, jacking and docking, NDT capability and broad EASA/FAA/GCAA type ratings across the Airbus and Boeing families and increasingly COMAC. Providers are either captive carrier MROs working their own and third-party fleets, or independent third-party airframe MROs selling man-hours by check. Buyers are airline procurement and fleet-technical teams scheduling heavy visits, and lessors commissioning redelivery checks.
"Emirates, Etihad, Qatar and Saudia run some of the world's youngest wide-body fleets (A380, 777, 787, A350) whose heavy checks are a major recurring procurement line. The Gulf is deliberately scaling base-maintenance hangar capacity to become a net exporter of MRO — Etihad Engineering's five wide-body hangars at AUH and Saudia Technic's Jeddah complex are anchor assets, and DAE-owned Joramco at Amman feeds Gulf lessor demand. Vision-2030 aerospace-localisation targets in Saudi Arabia add further hangar build-out."

Key evaluation criteria for Gulf procurement
- Type ratings — confirm EASA/FAA/GCAA approvals across the exact fleet types, including A380 and A350 where relevant.
- Hangar capacity & slots — wide-body bays and realistic slot availability against the heavy-check schedule.
- Man-hour pricing & turn time — independents sell by check; weigh man-hour rate against committed turn time.
- NDT & composite capability — structural and composite repair plus in-house NDT for major checks.
- Lease-redelivery experience — lessors need providers fluent in redelivery-check standards.
