According to Mordor Intelligence, the aircraft engine MRO market size is expected to grow from USD 48.91 billion in 2025 to USD 50.67 billion in 2026 and is forecasted to reach USD 61.66 billion by 2031 at a 4.00% CAGR over 2026-2031.

This report is Segmented by Engine Type (Turbine Engine and Piston Engine), Aviation (Commercial Aviation, Military Aviation, General Aviation, and UAVs), Service Providers (Airline In-House MRO, Independent Third-Party MRO, and More), and Geography (North America, South America, Europe, Asia-Pacific, and the Middle East and Africa). The Market Forecasts are Provided in Terms of Value (USD).
Airbus reported 19,233 A320-family orders, with 7,262 units still undelivered. Notably, 72% of this backlog consists of A321neo variants, which accumulate 3,000-3,500 flight hours per year. Boeing 737 MAX operators in Asia-Pacific and Latin America routinely fly 11-12 block hours daily, shortening first shop-visit intervals on LEAP-1A and -1B engines to 8,000-9,000 cycles. This compression forces MROs to invest in modular tooling and flexible bays that absorb unpredictable surges, as demonstrated by Lufthansa Technik and ST Engineering facilities commissioned in 2024. Certification under FAA and EASA Part 145 remains essential to scale these high-cycle workloads. Consequently, the aircraft engine MRO market increasingly rewards providers that can synchronize manpower, tooling, and parts logistics without extending turnaround times.
Pratt & Whitney's powder-metal contamination has sidelined more than 1,200 GTF engines, stretching shop visits to 250-300 days and grounding up to 12% of the active fleet. CFM International is simultaneously rolling out ceramic-matrix-composite shrouds and advanced coatings to fight blade erosion in dusty regions, compelling airline budgets to include inspections every 4,000-5,000 cycles. Delta TechOps increased GTF throughput by 30% to 450 annual shop visits after investing USD 50 million in tooling and additional staff. Pratt & Whitney has earmarked USD 3 billion for accelerating parts production and establishing regional repair hubs in Singapore and Poland. This mandatory work injects near-term volume but also heightens dependency on OEM-owned technical data, intensifying competition inside the aircraft engine MRO market.
Boeing forecasts a need for 132,000 new maintenance personnel by 2043, while US retirements reach 14,500 annually against 6,000-8,000 graduates from FAA-approved schools. European data indicate that 20% of mechanics are over 55, with limited cross-border mobility due to EASA Part 66 regulations. Starting salaries of USD 45,000-55,000 trail those of the technology sector, fueling attrition. MROs are automating borescope inspections and AI-assisted defect detection, but regulators still require human sign-offs, capping productivity gains. Labor scarcity, therefore, hinders the growth trajectory of the aircraft engine MRO market.

Turbine engines captured 74.36% of the aircraft engine MRO market share in 2025, with a projected annual growth rate of 5.32% during the forecast period, driven by their widespread use across commercial, military, and business jet fleets. Turbofan families, such as the CFM56, LEAP, Trent, and GEnx, generate the majority of shop visits, supported by high cycle counts on the A320 and 737 fleets. Turboprop demand follows regional aviation use of Pratt & Whitney Canada PT6 powerplants that exceed 400 million flight hours, turboshaft engines power over 20,000 UH-60 and AH-64 helicopters with GE T700 variants, keeping rotorcraft MRO steady.
Piston engines are projected to rise at a moderate CAGR as general aviation and UAV fleets expand; overhauls occur every 500-1,000 hours on delivery drones, bringing new revenue streams. Standardization under ASTM F3201 is expected to streamline the approval process for UAV maintenance. This trend positions niche providers to anchor specialization within the aircraft engine MRO market size for smaller propulsion categories.
North America accounted for 29.91% of 2025 revenues, with mature commercial and military fleets serviced by Delta TechOps, StandardAero, and AAR facilities that manage over 1,000 annual shop visits. Technician shortages, however, push wages higher and limit expansion pace, while proximity to GE, Pratt & Whitney, and Honeywell sustains rapid parts logistics.
Asia-Pacific, advancing at a 6.65% CAGR, recorded more than USD 600 million of investment in 2024 alone, including GAMECO's USD 500 million LEAP and Trent project in China and Pratt & Whitney's USD 200 million joint venture with Air India. ST Engineering has committed USD 100 million to developing wide-body capability in Singapore, while Rolls-Royce operates a Trent hub there. The regional fleet is forecast to exceed 17,000 aircraft by 2043, reinforcing long-term workload within the aircraft engine MRO market.
Europe's established players, Lufthansa Technik, Air France-KLM, and SR Technics, continue to expand; Lufthansa Technik has invested USD 150 million in Poland for Trent XWB and GEnx work. Safran doubled LEAP capacity in Morocco, illustrating a southward shift toward cost-competitive labor. The Middle East leverages state backing at Sanad and Turkish Technic to capture regional workloads. South America and Africa remain under-served, forcing operators to ferry engines abroad and inflating logistics costs, an imbalance that signals future white-space within the aircraft engine MRO market.
