N475AE

This airframe, N475AE, is a 2001-built Bombardier Challenger 604 (CL-600-2B16) with manufacturer serial number 5516, constructed by Bombardier Aerospace. The airframe is recorded as owned by the corporate entity 4S AIR LLC, and is registered in the US. Notable registry events and operator base assignments are not published beyond corporate ownership; the aircraft carries an estimated market valuation of $4,500,000.

The airframe is certificated for up to 22 seats but is typically fitted in a conventional executive arrangement seating 10–12 passengers with double-club and divan options; the installed cabin configuration for this specific entry follows the typical executive 10–12 place layout. Avionics are fitted with a Rockwell Collins Pro Line 4 suite, with common upgrade paths including Pro Line Fusion/ProLine Fusion upgrades. Typical mission profiles for this Challenger 604 airframe include medium- to long-range corporate and charter operations enabled by a ferry/mission range of 3,756 nm and a cruise speed near 459 kts; these characteristics support transcontinental and overwater trips within the aircraft’s operational ceiling of 41,000 ft. Maintenance and outfitting considerations for this specific aircraft will reflect installed systems and corporate ownership, with avionics upgradeability frequently cited as a modernization pathway.

The Bombardier Challenger 604 (CL-600-2B16) occupies the midsize long-range business jet niche, powered by two General Electric CF34-3B turbofans producing 9,220 lbf each, balancing cabin capacity with intercontinental capability. Competing models in the segment include upgraded variants of the Challenger family and similar types from other manufacturers; buyer and charter demand can favor airframes with Pro Line Fusion upgrades and verified maintenance records. Resale and maintenance considerations for a 2001 Challenger 604 such as N475AE typically center on avionics modernization, engine and APU cycles, and completion condition relative to its estimated value of $4,500,000.
