Model & Market Context
The airframe bearing registration N628EK is a 1982-built Learjet 55, constructor serial 071, manufactured in the Gates Learjet lineage (Learjet / Bombardier Learjet heritage). The documented owner is Kauffman Land & Development LLC of Fort Lupton, CO, US, and the aircraft carries a US civil registration. The airframe retains its original Collins-era avionics in many installations, though similar airframes often receive EFIS/ProLine retrofits; the listed market valuation for this specific ship stands at $900,000. No additional historical sales or notable registry actions are published beyond the current ownership and registration details.
This specific Learjet 55 is FAA-certified for 13 seats but is commonly found in executive configurations; typical interiors for the type provide a 6–8 club seating arrangement with an aft lavatory and forward galley, an interior layout consistent with many executive operators. With original Collins-era avionics fitted on this airframe, operational crews may plan for legacy panel workflows unless an EFIS/ProLine retrofit has been installed. Typical missions for this model and configuration include regional and transcontinental corporate transport within the aircraft’s quoted range of 2,244 nm, operating from the owner’s base area in Fort Lupton, CO and surrounding regional airports. Maintenance considerations reflect the age (1982 build) and popular aftermarket upgrades for avionics and engine program eligibility.
The Learjet 55 occupies a mid-size, high-performance light business jet niche, offering a blend of transcontinental range and high-altitude capability to 51,000 ft. Competing models historically include other light-to-midsize business jets of the era; buyer interest typically targets cost-conscious operators seeking solid cruise performance (420 kts) and a compact cabin with up to 13 certified seats. Resale and ownership considerations for this airframe center on updated avionics retrofits, engine program status for TFE731-series powerplants, and the airframe’s maintenance history relative to its 1982 build year.
