Spending on aircraft engine maintenance, repair, and overhaul is set to surpass $56 billion in 2026, with the engine MRO market valued at about $56.5 billion for the year, according to Mordor Intelligence. The segment is forecast to grow from roughly $42.71 billion in 2025 toward $58.16 billion by 2030, a compound annual growth rate near 6.37 percent.

Engine work commands the highest value in aircraft maintenance because of the precision and cost of modern powerplants. As airlines keep older aircraft flying longer, engines accumulate more cycles and require more frequent shop visits, lifting the volume of overhaul work that flows to specialized facilities.

Capacity is the binding constraint. Forecasts suggest engine MRO demand could outstrip available shop capacity by more than 17 percent before the end of the decade. Technician shortages, long parts lead times, and limited test-cell availability have slowed efforts to add throughput, even where demand is clearly present.

The figures underline why engine shops have become the pacing item for the wider maintenance market. With demand rising faster than capacity, backlogs at major engine facilities are expected to persist, and operators are booking shop slots further in advance to secure turnaround times for their fleets.
