RADAR ESTIMATE
What N100KZ is worth, and where it’s heading.
Radar's value model doesn't cover the Learjet 45 on its own yet, so this borrows the Cessna Citation XLS+ curve, scales it to N100KZ's listing-based estimate and widens the range to match. An estimate, not an appraisal.

RESEARCH NOTES
About N100KZ
Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.
Overview
This airframe, registered as N100KZ, is a Learjet 45 built in 1999 with serial number 45-065. The aircraft was manufactured by Learjet (Bombardier Aerospace) and is registered in the US; it is owned by the corporation Lear 100KZ LLC, headquartered in Austin, TX, US.
Operations & Cabin
The cabin of this specific Learjet 45 is configured as an executive 8-passenger double-club with lavatory and features tan leather upholstery as noted in the sale listing, while the aircraft maintains a certified seating complement of 12. Avionics are listed as a Collins Proline 4 WAAS/LPV/ADS-B fit per the airframe’s sale materials, supporting current navigation and surveillance mandates and enabling precision approaches. Typical mission profiles for this airframe would include short-to-medium-range corporate or charter flights within the aircraft’s 1,968 nm range at a cruise speed near 444 kts, based out of its owner’s Austin, Texas location. Maintenance considerations for this airframe follow Learjet 45 program norms, with attention to Honeywell TFE731-20-series engine support and avionics logbook compliance for ADS-B and WAAS/LPV capabilities.
Model & Market Context
The Learjet 45 family occupies a light-corporate jet niche focused on high-speed cruise and high-altitude performance, exemplified by this airframe’s 51,000 ft ceiling and 444 kt cruise. Competing models in similar missions include early-model Cessna Citation series and early Gulfstream entry-level jets; buyers typically value the Learjet 45 for speed and climb performance. Resale and maintenance considerations for a 1999-build Learjet 45 include airframe hours, engine program status for the Honeywell TFE731-20 series, and the presence of upgraded avionics such as Collins Proline 4, which can positively affect marketability.
