N453SC

This airframe, registered as N453SC, is a Learjet 45 built in 1999 with serial number 45-017 by Learjet Inc (Bombardier Aerospace). The certificate and registry reflect ownership by SOUTHERN CROSS AIRCRAFT LLC, an LLC based in Fort Lauderdale, FL, US, which operates the aircraft from its U.S. registry. The airframe is a fixed-wing, multi-engine business jet configured for executive use; its market valuation is listed at $2,400,000, indicating an airframe in line with late-1990s Learjet 45 examples and typical maintenance and depreciation expectations for the type. Notable registry points include the U.S. registration and the certification listing of 12 seats despite a typical executive cabin layout with fewer passenger seats.

The onboard cabin for this specific Learjet 45 is described as a typical 8-place executive double-club layout with a forward galley and an enclosed aft lavatory, while registry documentation cites a certification value of 12 seats, reflecting maximum approved seating rather than typical cabin configuration. Avionics installations for this airframe align with common fits for the model, typically Honeywell Primus 1000 / Primus II suites, supporting IFR business operations and modern navigation and communications capability for its era. Typical mission profiles for this aircraft emphasize short- to medium-range executive transport within a radius commensurate with its 1,690 nm range and cruise speed of 438 kts, operating from its Fort Lauderdale base for charters, corporate shuttles, or private transport. Maintenance considerations follow those of the model family, with attention to turbine engine upkeep for the TFE731-20AR powerplants.

The Learjet 45 occupies a performance niche within light-medium business jets, offering high cruise speed and a service ceiling to 51,000 ft, suitable for rapid point-to-point executive missions. In the market, it competes with contemporaries that prioritize speed and climb performance over some newer cabin comfort standards; demand historically comes from corporate operators and charter companies seeking efficient, fast regional travel. Resale and upkeep considerations for this 1999 airframe centered on remaining hours and cycles, avionics standardization such as the Honeywell Primus 1000 / Primus II, and the cost profile implied by its $2,400,000 valuation.
