Broker descriptions for this specific airframe list a nine-passenger executive cabin arranged in a double-club configuration with a forward galley and an aft lavatory, though the listed seating capacity is 12. Avionics references and listing/upgrade material indicate a Garmin G5000 fit or typical upgraded glass avionics consistent with broker material for this airframe. With a maximum cruise near 436 kts and a mission range of roughly 1,968 nm, the airframe is configured for point-to-point corporate and charter missions within continental distances, supported by a service ceiling of 51,000 ft that enables high-altitude cruise profiles. Specific unique amenities or maintenance records for this airframe are not published.

The airframe is a member of the Learjet 45 family produced by Learjet Inc, a fixed-wing multi-engine design intended for light to midsize business-jet missions. Its performance numbers — notably the 3,850 lbf-rated Honeywell TFE731-40BR-1 engines and a 51,000 ft ceiling — reflect the Learjet 45’s niche as a fast, high-altitude corporate transport. Broker materials noting upgraded glass avionics such as the Garmin G5000 are typical of market refurbishments aimed at maintaining charter appeal and resale competitiveness. Maintenance and resale considerations for this airframe would follow Learjet 45 norms and any specific logbook or refurbishment history, which are not published for this aircraft.
