N7886

This airframe, registered as N7886, is a 2003-built Bombardier Challenger 604 (CL-600-2B16) bearing serial number 5559. The airframe is recorded as owned by POLAR BEAR EXPRESS II LLC, an LLC based in Las Vegas, NV, US, which represents the principal change in the aircraft's civil registry history. The Challenger 604 is registered in the US and, as of available data, remains configured and operated consistent with business aviation use; specific recent valuation or condition reports are not published in the supplied data.

This specific Challenger 604, while listed with a certified maximum of 22 seats in a high‑density configuration, is typically outfitted in an executive interior described as a 10–12 place layout split across two cabin zones: a forward club and an aft club/divan, providing a conventional long‑range business jet arrangement. The avionics fit for the type is the Collins Pro Line 4, which supports long‑range IFR operations and common charter/operator flightdeck procedures. With a 4,000 nm ferry range and a cruise near 459 kt, missions commonly include transcontinental and trans‑oceanic business travel; operating base and maintenance oversight are expected to be organized from the owner’s Las Vegas, NV location. Routine maintenance considerations follow Challenger 604 fleet practices for CF34 engine shop visits and Pro Line 4 avionics support.

The Bombardier Challenger 604 sits in the large-cabin, long‑range business jet niche, offering transcontinental capability and higher passenger capacity versus light and midsize jets. Competing models include later Challenger variants and large-cabin types from Gulfstream and Dassault in similar mission roles. Buyers and charter operators value the 604 for cabin comfort and range, while maintenance and resale factors hinge on CF34 engine cycles, avionics upgrade status (Pro Line 4 vs. modern upgrades), and interior refurbishment history for an airframe built in 2003.
