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] 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] 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] 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 parts delivered directly to maintenance providers as certified spares, and Pratt & Whitney has developed a directed energy deposition repair method for GTF engines that reduces repair time by over 60%.
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.[^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] 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]
