Engine maintenance is pulling an ever larger share of aviation aftermarket spending, according to industry analysis reviewed by Aviation Pros. Engine work is projected to account for 53 percent of the commercial aftermarket 139 billion dollars in revenue in 2026, up from 49 percent in 2025 and 46 percent in 2024. The shift reflects the rising cost and complexity of modern engines, along with labor and parts inflation that push shop bills higher.

The overall maintenance market is forecast near 97 billion dollars in 2026, up from about 91 billion the prior year, growing at a compound annual rate close to 5 percent through the end of the decade. Analysts describe the period as a maintenance super cycle, a prolonged stretch of elevated demand driven by aging fleets, aircraft delivery delays, and heightened utilization. Older jets stay in service longer when new deliveries slip, and each additional flight hour brings inspection and overhaul work forward.

Newer geared turbofan and LEAP engines add another layer of demand as early fleets reach their first heavy shop visits. The figures point to a market where engines set the pace. As their share of spending climbs, shops with engine capacity and skilled technicians capture the largest gains. Parts availability and workforce depth remain the main constraints on how fast that capacity can grow.
