Used turboprop inventory tightens further in June 2026, extending a seven-month downward run and pushing asking prices higher, even as the pre-owned jet segment tells a more complicated story of falling availability alongside declining values, according to market data published by Sandhills Global on 6 July 2026.
Used turboprop inventory tightens as seller leverage holds
The turboprop segment produced the clearest pricing signal in the June data. Global used turboprop inventory fell 5.15% month over month and 13.67% year over year, while asking prices rose 3.12% from May and 3.32% from June 2025. That combination of contracting supply and rising asking values indicates that sellers of quality turboprops retain meaningful leverage, particularly where buyers face limited model-specific choices.
Terrin Mohl, Controller Sales Manager, said: ‘Aircraft inventory remains tight across much of the market, particularly among jets and turboprops, where inventory levels are still trending lower compared to last year. Used turboprops have seen sustained declines for over six months, while piston-single aircraft inventory has remained relatively stable.’
Sandhills owns Controller.com, the platform from which the underlying listings data is drawn. The company tracks movements through its Sandhills Equipment Value Index, which draws on retail and auction markets as well as model-year equipment actively in use.
Pre-owned jets: inventory shrinks but pricing power does not follow
The pre-owned jet market is moving in a different direction on price despite similar supply pressure. Global jet inventory fell just 0.15% month over month in June, but was down 19.21% year over year, with large-jet availability recording the steepest annual decline at 40% below June 2025 levels. Yet asking values moved against what a supply-constrained market might suggest: jet asking prices fell 2.28% month over month and 4.48% year over year.
Within the segment, super-midsize jets posted the largest monthly asking-value decline, down 4.4%, while midsize jets showed the largest annual decline at 6.54%. The divergence between shrinking inventory and softening values indicates a selective market in which buyers are still able to negotiate, even with fewer aircraft to choose from.
The June figures follow a pattern that was already visible in May. Controller.com’s May 2026 market report recorded pre-owned jet inventory dropping 3.97% month over month and 16.28% year over year, suggesting the annual supply compression has been building consistently across the first half of the year rather than accelerating sharply in a single month.
Piston singles and Robinson helicopters: supply down, values mixed
In the US and Canada piston-single market, inventory rose 2.48% from May but remained 14.08% lower than a year earlier. Asking values slipped 0.61% month over month and 0.74% year over year, a relatively contained move compared with the jet category.
Robinson piston helicopter supply is also contracting. Global used Robinson piston helicopter inventory fell 7.45% month over month and 17.14% year over year in June. Asking values fell 3.14% from May, though they remained 3.05% higher than June 2025, leaving the annual price trend still positive even as monthly values dipped.
Across all four categories covered in the June data, pre-owned jets, single-engine piston aircraft, turboprops and Robinson piston helicopters listed on Controller.com and other Sandhills platforms worldwide, inventory is lower than a year ago. The divergence is in how sellers are responding: turboprop owners are holding firm on price, while jet sellers are trimming values to move stock in what remains a supply-constrained but price-sensitive environment.
Sandhills is scheduled to publish its next monthly aircraft market data in August 2026, which will indicate whether the turboprop asking-price trend continues to firm or whether the broader jet-market softness begins to weigh on other categories.
