Global commercial aviation maintenance, repair, and overhaul demand is projected to grow at a 3.2% compound annual growth rate from 2026 through 2035, with engine MRO work representing the fastest-growing and highest-revenue subsegment, according to projections from Aviation Week Network and Exactitude Consultancy.

Key data points from the global and US MRO market in 2026:

- Global MRO market projected value: $155 billion by 2034 - US MRO market size: approximately $29.9 billion in 2026 - Engine MRO growth driver: aging narrowbody fleets and extended time-on-wing increasing maintenance demand - IATA and CFM International renewed their pro-competitive engine MRO agreement through February 2033 in January 2026 - Digital transformation investment is accelerating, with predictive maintenance analytics and AI-assisted inspection tools being deployed at major MRO facilities - Global commercial aviation fleet backlog at Boeing and Airbus extends well into the next decade, sustaining long-term MRO demand

Aircraft Maintenance Technician shortages remain the most acute operational constraint for the global MRO sector. The International Air Transport Association and ARSA have called for accelerated technician pipeline development through apprenticeship and technical training partnerships.

The US MRO market benefits from a large domestic commercial and military aviation fleet, stable regulatory oversight through the FAA's Part 145 framework, and proximity to major aerospace manufacturing corridors in the Southeast, Midwest, and Pacific Northwest.
