N18AX

This article covers the specific Learjet 45 airframe bearing registration N18AX, serial number 548. Manufacturer records attribute the type to Learjet Inc; the documented owner is N18AX LLC (an LLC based in Tulsa, OK, US). Operator and detailed transaction history are not published in the supplied data; the aircraft is registered in the US and carries an assessed value of $2,272,500. Registry entries list a 12-seat configuration and associate the airframe with its Tulsa, Oklahoma owner.

The airframe is outfitted with a flat-floor executive cabin that typically accommodates a 7–9 passenger executive layout with a forward galley and an aft lavatory, while registry information specifically lists 12 seats. Avionics fit is described as Honeywell Primus-series, using typical Primus 1000/Primus II displays for flight, navigation and systems integration. Operational profiles for this registration would align with short- to medium-range executive transport missions between regional business centers, leveraging its cruise speed of 436 kts and a maximum operating ceiling of 51,000 ft for efficient point-to-point travel. Based at or operated from the owner’s location in Tulsa, OK, the airframe’s configuration supports corporate travel, on-demand charter or owner-operated business use; specific maintenance history and unique onboard amenities beyond the standard cabin fit are not published.

The airframe belongs to the Learjet 45 family, positioned as a light-medium business jet offering transcontinental capability within the small-cabin segment. Its combination of 1,700 nm range, 436 kts cruise speed and dual Honeywell TFE731-20 engines places it against contemporaries in the light business jet market seeking fast cruise and high-altitude performance. Typical buyer demand targets corporate owners and charter operators valuing speed and climb performance; resale and maintenance considerations commonly focus on avionics upgrades, engine cycles and interior refurbishment, all factors reflected in the aircraft’s assessed value of $2,272,500.
