N643EP

This airframe, registered as N643EP, is a Learjet 45 with manufacturer serial number 599. The jet is owned and held in trust by AEROSPACE TRUST MANAGEMENT LLC TRUSTEE, located in Wilmington, DE, US; the current record indicates the aircraft is registered in the United States. Publicly available build year and earlier ownership history are not provided in the supplied data. The registry entry identifies the airframe as a fixed-wing multi-engine business jet with the typical Learjet 45 configuration; no specific valuation, damage history, or notable registry actions were supplied for this individual aircraft. The owner's trust status suggests the aircraft is managed for corporate or beneficiary use rather than being listed to a private individual.

The cabin is fitted in the typical Learjet 45 executive layout—double-club seating with a flat floor, a forward galley and an aft lavatory—supporting an occupancy profile of approximately eight to twelve passengers depending on final interior configuration. Avionics fit for the type is the Honeywell Primus 1000 suite, a widely used integrated flight deck on this model that supports regional high-speed transcontinental missions and common business-jet instrument procedures. Typical mission profiles for this airframe include short to medium-range corporate transport, on-demand charter sectors and executive repositioning flights within its approximately 1,700 nm radius, operating from the owner’s likely bases in the U.S. Maintenance considerations follow Learjet 45 schedules for its Honeywell TFE731 engines and airframe inspections; ownership in trust can affect custody, maintenance oversight and records access.

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 operators seeking rapid point-to-point travel and performance from smaller airfields. Competing models historically include the Cessna Citation Excel/Bravo series and mid‑generation Bombardier Learjet derivatives; demand is typically driven by fractional, charter and corporate buyers who value speed and climb performance. Resale and maintenance considerations for this specific airframe center on engine TBOs for the Honeywell TFE731-20, avionics commonality with the Honeywell Primus 1000, and the completeness of logbooks under trust ownership.
