N57TS

This entry covers a specific airframe, the light business jet registered as N57TS, a Learjet 31A built by Learjet Inc in 2002 with manufacturer serial number 236. The airframe is recorded as owned by AIRCRAFT TRUSTEE SERVICES INC TRUSTEE (a corporate trustee) based in Dover, DE, US, and remains on the U.S. civil register. The trustee ownership indicates the airframe has been held under asset-management or lien-related oversight rather than active single-owner private operation. Valuation records list the airframe at $1,750,000, reflecting market condition and typical 31A age-related depreciation.

The cabin for this airframe aligns with typical Learjet 31A configurations: a six–eight place executive club layout is standard, with forward belted lavatory and divan options reported for 31A layouts that may be present depending on specific interior refits. Avionics on the typical 31A fitment for this airframe include Bendix/King EFIS-50 displays paired with a KFC-3100 autopilot, though upgraded avionics are possible and commonly installed during lifecycle updates. Operationally the airframe’s performance—high cruise speed and transcontinental-ish range—suits short to medium business missions, positioning it for owner-flown executive transport or charter under trustee-directed management out of its Delaware registration base. Maintenance considerations center on the twin Honeywell TFE-731 series turbines and periodic avionics modernization when transitioning between owners or operators.

The Learjet 31A family occupies a performance niche as a light, high-speed business jet with a high-altitude ceiling and compact cabin. Competing models in the market segment include other light jets offering similar speed and range, and demand is typically driven by owner-operators and light charter operators seeking cruise performance over cabin volume. Resale and maintenance considerations for this 2002 airframe emphasize engine life, avionics upgrade paths (common with EFIS-era cockpits), and the impact of trustee-held status on transferability and lien clearance during sale.
