RADAR ESTIMATE
What N125FS is worth, and where it’s heading.
Radar's value model doesn't cover the Learjet 31A on its own yet, so this borrows the Embraer Phenom 300/300E curve, scales it to N125FS's listing-based estimate and widens the range to match. An estimate, not an appraisal.

RESEARCH NOTES
About N125FS
Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.
Overview
This entry covers airframe N125FS, a production serial 125 Learjet 31A built in 1996 by Learjet Inc (Bombardier Aerospace). The aircraft is registered in the US and is recorded as owned by Aircraft Trustee Services Inc Trustee (a corporate trustee based in Dover, DE, US), a documented ownership arrangement that may reflect asset-management or custodial status rather than an individual operator. Historical registry notes include the transfer into the corporate trust; no prior owners are published in the supplied data.
Operations & Cabin
As registered, N125FS is a fixed-wing multi-engine business jet configured with 10 seats consistent with Learjet 31A cabin layouts; specifics of seating arrangement, galley or lavatory fit are not published in the supplied data. Typical mission profiles for this airframe, given its 1,290 nm range and 441 kt cruise, would center on short to mid-range executive transport and time-sensitive light cargo or patient transfer roles; actual usage depends on the trustee’s operator selection and any charter permissions. The twin Honeywell TFE731 engines rated at 3,500 lbf each support higher-altitude cruise up to the documented 51,000 ft ceiling, which drives maintenance considerations such as hot-section inspections and specialized pressurization system service intervals. The corporate trust ownership suggests centralized maintenance oversight and recordkeeping, although no specific maintenance status is provided.
Model & Market Context
The Learjet 31A occupies the light business jet niche, offering high cruise speeds and a high operating ceiling relative to many peers. Competing models in its class historically include other light-cabin jets that prioritize speed and climb performance; buyer and charter demand for such airframes depends heavily on life-limited component status and overall records.
