RADAR ESTIMATE
What N121LJ 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 N121LJ's listing-based estimate and widens the range to match. An estimate, not an appraisal.

RESEARCH NOTES
About N121LJ
Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.
Overview
This airframe, registered as N121LJ, is a 1996-built Learjet 31A with manufacturer listed as Bombardier Aerospace and serial number 31A-0121. The aircraft is owned by N121LJ LLC, a corporation based in Elmira, NY, and operates on the US registry.
Operations & Cabin
The airframe is outfitted in a 7-place executive cabin layout, described as a 7-place executive layout with large entry upgrade and belted lavatory options, supporting executive light-jet missions and short cross-country trips. Avionics remain the original Bendix/King EFIS/KFC-3100 autopilot legacy architecture augmented with WAAS/LPV and ADS-B Out, and the installation includes XM Weather for enhanced en route meteorological information. Typical mission profiles for this aircraft under corporate ownership center on point-to-point business travel within its 1,290 nm range and high-speed cruise capability of 441 kts, with transcontinental legs requiring fuel stops. Maintenance considerations for this specific airframe include continuing support for legacy Bendix/King avionics platforms and the Honeywell TFE731 engine series, both of which have established aftermarket pathways but can entail avionics upgrade planning for long-term operational relevance.
Model & Market Context
The Learjet 31A family occupies the light, high-performance business jet niche, valued for fast cruise speeds and high service ceilings up to 51,000 ft, directly competing with other light jets in the 4-8 passenger class. Prospective owners often weigh the costs of avionics modernization and engine lifecycle events against mission needs and the platform’s strong cruise and ceiling performance.
