On Wing Support
OEM-staffed global line-maintenance network that dispatches trained technicians within 24 hours to perform engine repairs on the aircraft — eliminating unscheduled removals wherever possible.
On Wing Support (OWS) is GE Aerospace's field-deployed engine repair service, positioned as an operator's first escalation before an unscheduled engine removal is initiated. The operation runs seven strategically placed stations — Dallas-Fort Worth, Cincinnati, London Heathrow, Doha, Dubai, Shanghai, and Seoul — staffed by more than 300 OEM-trained technicians who can travel to any operator location worldwide. Each station maintains a 24/7 AOG response posture, with a documented target of reaching the aircraft within 24 hours of a customer call. Technicians are equipped with the Global Tooling Center's inventory of over 25,000 maintenance tools and carry OEM-supplied parts, allowing them to execute a wide range of on-aircraft workscopes: borescope inspection and blade blending, line replaceable unit removal and replacement, fan module swap, gearbox repair, and quick engine change. For cases requiring module-level intervention, OWS operates quick-turn shops capable of servicing fan, compressor, combustor, high-pressure turbine (HPT), and low-pressure turbine modules. Supported engine families span the full GE Aerospace commercial portfolio plus CFM56 and LEAP — the latter representing OWS's highest growth workload as the LEAP-1A and LEAP-1B fleet matures. The team has expanded HPT refresh capacity by 170 per cent on LEAP engines and has deployed AI-assisted white-light robotic inspection for high-pressure turbine components. Each of the seven stations holds multiple authority certifications including FAA, EASA, GCAA, QCAA, CAAC, and CAAT, enabling it to stamp work for GCC-registered aircraft. The Dubai DXB station gives regional airlines and lessors direct access to a permanent GE Aerospace line-maintenance presence in the Gulf.

Use cases.
- ›Narrowbody operators experiencing in-service LEAP or CFM56 HPT damage requiring on-wing blending or borescope assessment before a RON delay forces a removal
- ›Widebody operators at outstations needing GE90 or GEnx LRU replacement without ferry to a maintenance base
- ›GCC carriers requiring a local OEM-certified repair station (Dubai DXB) for line-level engine work under GCAA authority
- ›Lessors managing aircraft transitions who need OEM-stamped borescope reports to support return-condition negotiations
- ›Any operator seeking to avoid the cost and schedule impact of an unplanned engine removal through rapid on-wing intervention
