N604AU

This entry describes airframe N604AU, a Bombardier CL-600-2B16 Challenger 604 built in 1999 with manufacturer serial number 5434. The airframe is listed in trust ownership as BANK OF UTAH TRUSTEE, a corporate trustee based in Salt Lake City, UT, US, and is registered in the US. The Challenger 604 configuration, registration and trustee ownership indicate use in corporate transport or commercial on-demand operations rather than private single-owner display; specific operator or home base details beyond the trustee location are not published. No contemporaneous valuation or condition report is provided in the registry data supplied.

The registry entry for N604AU records a typical executive two-zone cabin fit for the Challenger 604 family while also carrying a transport certification for 22 seats; commonly this airframe is fitted with an 8–12 executive seating plan but retains the capability and certification to operate as a higher-capacity transport. Avionics are listed as Rockwell Collins Pro Line variants typical to the 604 series, supporting advanced navigation, flight management and situational awareness for long-range executive or charter missions. With a near-4,000 nm range and a cruise around 459 knots, operational profiles for this airframe likely include transcontinental U.S. flights and medium-haul international hops; maintenance considerations follow CF34-series engine program requirements and Pro Line avionics support pathways typical of 1999-build 604s.

The Bombardier CL-600-2B16 Challenger 604 occupies the large-cabin, long-range business jet niche, offering transcontinental capability with robust payload and passenger flexibility. Competing models include late-1990s/early-2000s large-cabin types that emphasize range and cabin volume; buyer and charter demand historically favors 604s for their combination of performance and maintainability. For this specific airframe, the CF34-3B engine type and Pro Line avionics mean owners and operators consider established support networks and component life-limits when assessing maintenance cycles and resale positioning.
