N545SD

This article covers airframe N545SD, a Canadair-built business jet completed in 1989 with manufacturer serial number 5056. The airframe is a Canadair CL-600-2B16 Challenger 601-3A (manufactured by Bombardier Aerospace (Canadair)) and is registered in the United States (US) to Aj Aviation Holdings LLC of Fort Lauderdale, FL, US. The airframe is noted in auction material for its 11-passenger executive layout and is valued at $2,300,000 in the most recent listing. Registry and ownership records indicate the airframe has been operated from a Florida base under the listed LLC ownership.

The airframe's interior is described in auction material as an 11-passenger executive layout with a forward galley, forward crew station, and an aft lavatory, a configuration aimed at business and corporate transport missions. Specific avionics fit and modifications are not published in the provided data, so operators and maintenance planners should consult the aircraft logbooks for electrics, avionics and STC records. Typical mission profiles for this configuration, given the 3,430 nm range and 442 kt cruise, include transcontinental and medium-range international trips originating from the operator's Fort Lauderdale base. Maintenance considerations for this individual Challenger include age-related inspection regimes for a 1989 build and lifecycle management appropriate to aircraft with CF34-3A engines.

The airframe belongs to the Challenger 601-3A family produced by Bombardier (Canadair), a twin-engine business jet series characterized here by two General Electric CF34-3A powerplants and a high single-flight-endurance capability. As a 1989-built example offered at an indicated market value of $2,300,000, resale and maintenance considerations typically reflect airframe age, engine cycles, and the scope of interior refurbishment required to meet contemporary operator expectations. For buyers and charter operators, the combination of an 11-seat executive cabin, transcontinental 3,430 nm range and 41,000 ft ceiling defines the platform’s continued utility in the fixed-wing multi-engine business jet sector.
