N604EM

This specific airframe, registered as N604EM, is a 2001-built example of the Bombardier CL-600-2B16 Challenger 604 with manufacturer serial number 5492. The airframe is recorded as held under fractional ownership, and its U.S. registration reflects that it operates within the U.S. registry. Publicly available records do not publish an operator base or a detailed ownership timeline beyond the fractional ownership designation; likewise, no independent valuation or condition report is published for this entry. The combination of a 2001 build year and Challenger 604 pedigree places this airframe within a cohort commonly used in corporate, fractional, and charter roles.

This airframe is typically fitted in two-zone executive configurations, commonly a double-club/forward club plus an aft divan, although the registry certification can accommodate 22 seats; corporate fits for similar airframes more commonly seat 10–12. Avionics in 604 conversions of this model are typically drawn from the Collins Pro Line family, with many examples carrying Pro Line 4 or Pro Line II derivative upgrades, which support sophisticated navigation and communication capabilities for long-range operations. Operational use for this specific Challenger 604 variant centers on transcontinental and offshore point-to-point missions enabled by a long-range 4,000 nm capability and a high-speed cruise of 459 kt; maintenance considerations follow Challenger 600-series common practices, particularly systems and engine shop visit cycles for the General Electric CF34-3B powerplants.

The Bombardier CL-600-2B16 Challenger 604 occupies the large-cabin, long-range business jet niche between mid-size and ultra-long-range types, offering transcontinental performance with corporate comfort. Competing models in its era and segment include upgraded variants of the Challenger family and other large-cabin business jets offering similar range and payload capabilities. Buyer and charter demand for 604s is influenced by cabin volume, range, and the availability of avionics upgrades (Collins Pro Line derivatives), while maintenance and resale considerations emphasize CF34 engine condition, airframe hours, and completion standard given the wide variety of corporate and fractional configurations.
