RADAR ESTIMATE
What N100FK 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 N100FK's listing-based estimate and widens the range to match. An estimate, not an appraisal.

RESEARCH NOTES
About N100FK
Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.
Overview
This write-up describes a specific airframe, N100FK, a Learjet 45 built by LEARJET INC in 2000 with serial number 113. The aircraft is owned by FK Air LLC, an LLC based in Newark, DE, US, and is registered in the US; the change of custody to FK Air LLC is the principal recorded ownership event for this tail.
Operations & Cabin
The cabin is fitted with a flat-floor executive arrangement and a typical 8-12-place executive seating layout, including a forward galley and a belted aft lavatory; this configuration remains configurable to suit operator requirements. Avionics are listed as Honeywell Primus 1000 as a typical fit, with the note that the suite may be retrofitted depending on owner upgrades. Typical missions for this airframe would align with business and executive transport profiles that leverage its transcontinental range of 1,970 nm and high-speed cruise of 436 kts, operating from the owner’s base in Newark, DE, US. Maintenance considerations for this airframe reflect twin Honeywell TFE731-20AR engines and the airframe age since its 2000 build year.
Model & Market Context
The Learjet 45 family occupies a light-medium business jet niche, offering high cruise speed and a 51,000 ft service ceiling that appeals to buyers seeking regional and cross-country capability. Competing aircraft in this segment typically emphasize cabin comfort versus payload-range tradeoffs; the 12-seat flexible cabin and flat floor support executive missions and charter usage.
