N345XB

The aircraft registered as N345XB is a 2005-built Bombardier CL-600-2B16 Challenger 604, serial number 5631, manufactured by Bombardier Inc. The airframe is recorded as owned by HILLTOP ASSET HOLDINGS LLC, an LLC based in Saratoga Springs, NY, US, and is certificated in the US registry. Documentation for this specific airframe notes standard market valuation and condition indicators consistent with mid-life Challenger 604 examples, with an estimated value of $5,000,000; no other public registry actions are recorded in the supplied data. The aircraft carries typical executive outfitting and is configured and maintained to allow both executive transport and higher-density seating under its airworthiness certification.

The cabin of N345XB features a typical executive two-zone layout arranged for a 9–12 passenger executive configuration while being airworthiness certificated for 22 seats, and includes a forward galley, full lavatory, and approximately 115 cu ft of baggage volume. Avionics fit is listed as Rockwell Collins Pro Line 4, the common baseline for CL-600-2B16 airframes, with many examples receiving incremental upgrades over time. Operational missions for this Challenger 604 typically include medium- to long-range corporate flights within its 4,077 nm range and transcontinental charters; maintenance considerations for this airframe follow the Challenger 600-series program and CF34-3B engine support requirements. The owner’s location in Saratoga Springs suggests Northeast US basing and deployment for both business and charter operations.

The Bombardier CL-600-2B16 Challenger 604 occupies the large-cabin, long-range corporate jet niche, valued for its combination of transcontinental range, roomy cabin, and robust systems. Competing models in the segment include late-model Gulfstream and Dassault offerings as well as earlier heavy-cabin Bombardier and Airbus corporate conversions; resale and buyer demand for the 604 is influenced by airframe age, engine cycles, and avionics fit such as Pro Line 4. Maintenance and resale considerations for this specific 2005 airframe center on CF34-3B engine support, refurbishment state of the two-zone executive cabin, and any avionic upgrade history that may enhance marketability.
