Used aircraft supply tightened significantly in June 2026, driving a sharp price divergence between turboprops and business jets. Global turboprop inventory fell 13.67% year-over-year, extending a seven-month downward trend, while asking prices rose 3.32% from June 2025 and 3.12% from May. Buyers face tighter availability for turboprops, piston singles, and helicopters. Conversely, business jet inventory increased slightly, with availability rising and prices softening despite a 12% year-over-year inventory decline noted in some reports. The sector now reflects a supply-constrained market where turboprops show the clearest upward price signal, contrasting with mixed trends in other categories. Operators must navigate reduced stock levels across all segments, with new production not yet flooding the used market.
