Engine work accounts for more than 46 percent of total North American commercial maintenance, repair and overhaul demand over the next decade, and GE Aerospace powerplants carry 39 percent of that engine spending, worth 52 billion dollars, according to the Aviation Week Commercial Aviation Fleet and MRO Forecast.

GE Aerospace engines power over 72 percent of North American widebody aircraft today and are projected to power over 78 percent by the end of 2034. The active GE commercial engine population in the region moves the other way, falling from nearly 5,600 units in 2025 to just over 4,800 in 2034. Maintenance demand still climbs across the same period, rising by more than 225 million dollars as older engines require deeper shop visits and newer types enter their first heavy overhaul cycles. Total GE engine MRO demand grows just over 4 percent across the forecast, a compound annual rate near half a percent.

The CF6 family dominates near term demand at more than 35 percent of the GE total, followed by the CF34 and GENX families at 22 percent each. The mix shifts sharply by the end of the forecast window. GENX engine population more than doubles from roughly 610 units in 2025 to nearly 1,300 in 2034. GENX demand, estimated at 745 million dollars and 14 percent of GE engine MRO in 2025, climbs past 2.3 billion dollars and more than 42 percent of the total by 2034, an increase of 210 percent.
