Aircraft (Base) Maintenance Services
Full-spectrum heavy maintenance — A, C, and D checks — across narrow- and wide-body fleets from one of Europe's largest MRO hangar complexes.
Turkish Technic's Aircraft Base Maintenance service covers the complete scheduled and unscheduled heavy-check workload for commercial and cargo operators: A-checks through full D-check structural inspections, bridging checks, redelivery inspections, and modification embodiment. The programme spans Airbus A320-family, A330, A340 and Boeing 737 NG/MAX, 767, and 777 aircraft, with additional capabilities for A300/A310 legacy types. Work is performed at three main hangars — Istanbul Airport (IST), Sabiha Gökçen Airport (SAW), and Ankara Esenboğa (ESB) — giving the network 15 hangars and over 650,000 m² of enclosed area. The IST C/D Hangar complex alone spans 60,000 m² and can hold three wide-body and eleven narrow-body aircraft simultaneously; total simultaneous capacity across the network has reached 61 aircraft and is growing with a new IST hangar in progress. Annual throughput exceeds 600 base-maintenance events. Buyers choose this programme for its one-stop scope: the same organisation that performs the structural check can manage engine removals, avionics modifications, landing gear exchange, cabin interior renewal, and aircraft painting, eliminating co-ordination between separate shops and reducing overall aircraft-on-ground time. EASA Part 145 and FAA certifications are maintained. For GCC and Middle Eastern operators, Istanbul Airport sits within a four-hour ferry radius of most Gulf hubs, giving the facility genuine geographic convenience for supplementary maintenance capacity alongside the region's own MRO centres.
