N528MC

This airframe, registered as N528MC, is a 1996-built Bombardier CL-600-2B16 Challenger 604 carrying serial number 5328. The airframe is owned by BOREALIS PARTNERS LLC, an LLC based in Dallas, TX, US, and is listed on the US registry with its current ownership recorded there. The registry notes certificated seating for 22, and contemporary valuation records place the airframe at approximately $4,568,169, indicating a mature-market pricing point for a mid-1990s Challenger in operational condition.

The cabin for this specific Challenger 604 follows a typical 10–12-place executive layout arranged in two cabin zones, although the registry lists certificated seats as 22, and the standard installation includes a full galley and an enclosed aft lavatory. Avionics are commonly the Rockwell Collins Pro Line 4 suite, with operator-specific upgrades varying between examples; this airframe is commonly configured to business charter and corporate transport missions on medium‑ to long‑range sectors. Based in Dallas, Texas by ownership association, typical operations would include transcontinental flights and high-utilization charter work requiring the CL-600-2B16’s range and payload. Maintenance considerations for this airframe reflect CF34-3B engine supportability and fleet commonality for Pro Line 4 avionics, with inspection and component life-cycle work aligned to Challenger 604 maintenance programs.

The Bombardier CL-600-2B16 Challenger 604 occupies the large-cabin, long-range business jet niche, offering transcontinental capability and robust payload for its class. Competing models include upgraded variants of the Bombardier Challenger family and large-cabin offerings from Gulfstream and Dassault at higher price points. Demand in the pre-owned market favors well-documented maintenance history and avionics modernization; for a 1996 airframe like 5328, resale and charter appeal hinge on engines’ time‑since‑overhaul, Pro Line 4 avionics condition, and cabin refurbishment status.
