Aviation MRO
Aviation maintenance, repair, and overhaul (MRO) encompasses the inspections, repairs, modifications, and overhauls required to keep aircraft airworthy. The global aviation MRO market reached over $114 billion in 2024, surpassing pre-COVID levels, exceeded $136 billion in 2025, and is projected to approach $140 billion in 2026 — driven by an MRO "super cycle" of aging fleets, delivery shortfalls, and increased utilization.[^c1][^c2][^c3][^c10] The global military aircraft MRO market was valued at approximately $97 billion in 2025, with the combined commercial, military, and business aviation MRO market exceeding $114 billion in 2024.[^c28] By the end of the decade, spending is expected to approach $193 billion.[^c7] Engine MRO, the largest segment valued at $50–58 billion annually, is projected to exceed available capacity by more than 17% before the end of the decade.[^c21][^c22] The aircraft order backlog has surpassed 18,000 units and average fleet age reached a record 15.2 years, with supply chain failures costing airlines at least USD 11 billion in 2025.[^c32] In response, IATA identified four strategic priorities — supply chain visibility, aftermarket competition, data and AI integration, and workforce capacity — and partnered with the International Airlines Technical Pool (IATP) in June 2026 to improve parts visibility and materials pooling across the industry.[^c33][^c34] China's commercial aircraft fleet is projected to expand to 9,755 jets by 2044, with MRO capacity expanding to match, including SSAMC's certification as China's first LEAP Premier MRO provider, authorized for the LEAP-1C powering the COMAC C919.[^c9][^c16] Airbus subsidiary Satair finalized its acquisition of Unical Aviation and ecube in May 2026, creating an end-to-end USM provider with combined revenue of $298 million across seven sites.[^c30][^c31] The Middle East has emerged as a global MRO hub, with the Amman-Dubai-Riyadh triangle absorbing European MRO overflow as the region becomes "the engine room of global aviation."[^c29] See [[markets/market-overview]] for detailed market breakdown.
The sector is governed by a complex regulatory framework. In Europe, [[EASA Part 145]] establishes certification requirements for maintenance organizations and, since 2022, has mandated [[Safety Management Systems]] (SMS).[^c4] In the United States, [[FAA Part 145]] regulates repair stations, with SMS requirements expanding to U.S. stations holding EASA approvals.[^c5] [[EASA Part-IS]], effective 22 February 2026 for Part-145 organizations, requires the integration of information security management systems with existing safety and quality frameworks, with enforcement audits now underway.[^c20]
The MRO industry is contending with a severe [[Technician Shortage]], with Boeing's 2025 Pilot and Technician Outlook projecting a need for 710,000 new maintenance technicians globally over the next 20 years.[^c6][^c8] The Oliver Wyman 2026 survey forecasts a shortfall of 17,800 certified mechanics in the U.S. in 2025, expanding to 22,000 by 2027, with more than 40% of companies reporting increased direct labor attrition.[^c15] Labor rate inflation has settled at 5.5–6.0%, well above pre-pandemic averages. Material shortages and engine turnaround times remain among the top operational disruptors.
Technology adoption is accelerating across the sector. AI adoption among MRO organizations grew to 67% in 2026, with top applications spanning materials management, engineering reliability analyses, and airframe planning.[^c14] [[AI in MRO]] applications include inspection tools, generative AI assistants, warranty processing agents, and predictive analytics. [[Digital Twins]] enable real-time health monitoring and failure prediction, while [[Robotics and Automation]] are advancing toward the "smart hangar" concept. [[Additive Manufacturing]] has achieved certified production of metal aircraft components under EASA Part-21/G approval, with Pratt & Whitney developing a directed energy deposition repair for GTF engines reducing repair time by over 60%, and new techniques such as cold spray for structural airframe repairs emerging.
Sustainability is an increasing priority, with [[Aircraft End-of-Life and Sustainability]] practices including AFRA-certified recycling (achieving 83% reuse rates in operational benchmarks), used serviceable material (USM) programs reducing CO₂ emissions by 50–90%, and CORSIA offsetting obligations now in effect with a positive sectoral growth factor.
Engine OEMs are investing over a billion dollars each in MRO capacity expansion. GE Aerospace's global expansion program has reduced turnaround times by 25–50% and increased LEAP engine output by 25% in 2025, and GE rolled out its 360 Foam Wash cleaning technology across its MRO network in 2026.[^c19] Pratt & Whitney expanded its GTF MRO network to 21 global engine centers with output rising more than 20% year-over-year, and is adding capacity in New Zealand through a USD 150 million Christchurch Engine Centre expansion.[^c18][^c24] The GTF powder metal defect continued to impact the fleet, with 835 aircraft grounded at the peak, airlines such as Wizz Air keeping 35–41 aircraft grounded through 2025, and Airbus filing a damages claim over delivery shortfalls.[^c23] In June 2026, SIA Engineering Company and Safran Aircraft Engines signed a formal joint venture agreement for a USD 118 million LEAP engine MRO facility in Singapore, with Safran holding a 51% stake.[^c17] Collins Aerospace announced a USD 63 million expansion of its Subang, Malaysia MRO facility, quadrupling its footprint to 164,000 square feet.[^c26] In China, ST Engineering and SF Airlines inaugurated an airframe MRO facility in Ezhou with capacity for up to four widebody or eight narrowbody aircraft.[^c35] Bain Capital took a majority stake in FDH Aero, reflecting continued private equity interest in aerospace supply chain assets.[^c36] Major carriers such as Emirates are investing in large-scale in-house MRO facilities, including a USD 5.1 billion engineering complex at Dubai South, creating a structural shift in industry organization as airlines increasingly act as their own maintenance providers.[^c12][^c13]
Fuel price volatility in 2026 has added a new layer of complexity to MRO planning. Higher fuel costs led airlines to cut capacity and advance maintenance schedules, with regulated maintenance requirements ensuring that MRO demand remains resilient even as airlines adjust flight operations.[^c11] The Indonesian Air Force endorsed plans to develop Kertajati International Airport into a regional MRO hub for C-130 Hercules aircraft, reflecting broader regional capacity expansion in the Asia-Pacific.[^c27]
