N1821U

This airframe, registered as N1821U, is a factory-built Bombardier Challenger 604 (CL-600-2B16) completed in 2001 with serial number 5506. Owned by BANK OF UTAH TRUSTEE, a corporate trustee based in Salt Lake City, UT, US, the jet remains on the U.S. registry and carries the documented corporate ownership rather than an individual operator. The record for this airframe indicates standard registry actions associated with corporate ownership and U.S. registration; there are no additional published ownership transfers or operator changes in the provided data. Condition and valuation specifics are not published in the supplied data set.

This Challenger 604 airframe is fitted with a typical executive interior described as a 9–12-place layout within a large wide cabin measuring 28 ft in cabin length, although the aircraft retains certification for 22 seats overall. Avionics are listed as Collins Pro Line 4 with a note that many 604s are upgradeable to ProLine Fusion, indicating a platform that supports incremental avionics modernization. Mission profiles for this airframe align with transcontinental and long-range corporate transport—leveraging a 3,718 nm range and 425 kt cruise speed for nonstop coast-to-coast missions in the U.S. and international point-to-point trips. Maintenance considerations for this individual jet follow standard Challenger 600-series practices, particularly for CF34 engine support and avionics upgrade pathways; no unique amenities or deviations from typical 604 configuration are cited in the data provided.

The Bombardier Challenger 604 (CL-600-2B16) occupies the large-cabin business jet niche, offering long-range capability and a roomy cabin relative to light and mid-size competitors. It competes with late-model large-cabin types for charter and corporate buyers seeking range near 3,700 nm and a 41,000 ft service ceiling. Market considerations for this airframe class include availability of CF34 engine support, avionics modernization (Pro Line 4 → ProLine Fusion), and the appeal of a 28-foot cabin for executive comfort; resale and maintenance outlooks reflect these common upgrade and support pathways.
