N583PS

The airframe N583PS is a 2007-built Learjet 45 (serial number 331) manufactured by Learjet Inc and registered in the US. The aircraft is owned by CONQUEST EXPRESS LLC, an LLC based in Libertyville, IL, US, which serves as the operator/home base for this specific airframe. Notable registry action includes its continued US registration under the single corporate owner with no publicly recorded subsequent ownership transfers. As of the provided data the airframe is valued at $3,400,000, reflecting its age, systems fit and market position within pre-owned light business jets.

The cabin of this Learjet 45 is equipped in the typical double-club, flat-floor configuration accommodating 8–9 passengers in practical layout while the airframe carries a certified seating count of 12; the fit includes a forward galley, an enclosed aft lavatory and dedicated external and internal baggage compartments. Avionics for this specific airframe are the original Honeywell Primus 1000 installation, a four-tube EFIS with CRT displays as delivered from the factory. Typical missions for this airframe under a Libertyville, IL–based operator would include regional business charters and owner-operator corporate transport within the aircraft’s 1,710 nm range and high-speed cruise capability. Maintenance considerations for this individual jet reflect legacy CRT-based avionics and the ongoing support cycles for Honeywell TFE731 engines, which factor into dispatch reliability and upgrade planning.

The Learjet 45 family occupies a light-cabin, high-performance niche with transcontinental regional capability at company-competitive cruise speeds near 445 kts and a service ceiling of 51,000 ft. Competing models typically include other light-to-midsize business jets offering similar speed and range but newer avionics suites; as a result, buyer and charter demand for a 2007 Lear 45 often reflects tradeoffs between airframe performance, retrofit cost for modern EFIS, and the aircraft’s $3,400,000 market valuation. Maintenance and resale considerations for this specific airframe center on engine hours and the original Honeywell Primus 1000 CRT installation, which may prompt avionics modernization to maintain competitiveness in the pre-owned market.
