The shift toward engine-driven demand signals MRO providers and shops will need to weight capacity, tooling and labor toward powerplant work over the coming decade.
Engine maintenance events are projected to outnumber airframe maintenance events among European airline aircraft over the next 10 years, according to a 2026 Commercial Fleet & MRO Forecast.

Major MRO service events generated by European airline aircraft are expected to account for 23% of the world's total of 288,000 major events over that period.
This forecast points to a broader shift in how airline fleets consume maintenance resources, with engine work increasingly dominating the major-event mix rather than airframe checks.
In practice, engine shops, teardown facilities and parts suppliers tend to see demand rise as engine-off-wing events multiply, while airframe-focused heavy maintenance providers may see a smaller share of total major events even as overall fleet activity grows.
Whether this plays out as forecast will depend on how European carriers' fleets evolve and how quickly new engine types reach maturity, since the 288,000-event global total and the 23% European share are projections rather than counts already recorded.
