The global commercial aircraft maintenance, repair and overhaul market is valued at $100.99 billion in 2026, up from $96.29 billion the year before, and is forecast to grow to $128.17 billion by 2031 at a compound annual growth rate of 4.88%, according to market research firm Mordor Intelligence. Engine overhaul work accounts for the largest share of spending, capturing 46.12% of 2025 revenue, a reflection of how costly and technically demanding modern powerplant maintenance has become.

Commercial passenger airlines drove 66.12% of 2025 spending in the sector, while charter operators, a smaller slice of the market, are projected to grow fastest among end users at a 5.22% compound annual rate. North America remained the largest regional market, generating 38.60% of 2025 revenue on the strength of major maintenance hubs in Atlanta, Dallas and Miami, though Asia-Pacific is forecast to expand fastest overall at a 6.01% compound annual growth rate as governments there incentivize domestic maintenance capacity.

The report flags a persistent labor constraint on the industry's growth. A technician workforce study cited in the research found the commercial air transport segment was short roughly 10% of the certificated mechanics it needed in 2025, a gap expected to narrow to 7% by 2035 but still leave the sector about 10,000 mechanics short of demand, even as new engine shop capacity comes online globally.
