N605GS

This entry covers airframe N605GS, a 2011-built Bombardier CL-600-2B16 (Challenger 604) with serial number 5865. The airframe is registered in the United States and is owned by GREYSTONE AIRCRAFT HOLDINGS LLC, an LLC based in New York, NY, US; public records reflect that ownership and registry actions are tied to that New York-based entity. The Challenger 604 platform and this specific airframe have the common 2011-era fit and performance, with registry entries listing a 22-seat transport configuration that contrasts with the typical executive layouts often installed in the model.

Registry information for N605GS lists a 22-seat transport configuration; typical executive conversions for the CL-604 family would reduce that to 8–12 seats in two cabin zones, though the registry entry for this airframe remains a higher-density transport layout. The airframe is commonly fitted with Collins Pro Line 4 avionics in CL-604/605 installations, which supports modern flight-management, communications, and surveillance capabilities consistent with the platform. Typical missions for a Challenger 604 built in 2011 include medium-to-long-range corporate transport and transcontinental charters within its 3,750 nm range and cruise of 459 kts; the 41,000 ft ceiling allows for efficient high-altitude cruise profiles. Maintenance considerations for this specific aircraft align with CF34-3B engine support and Challenger-series structural checks as managed by its New York-based owner/operator.

The Bombardier CL-600-2B16 (Challenger 604) occupies the large-cabin super-midsize business jet niche, offering transcontinental range and a roomy cabin relative to light and midsize competitors. Competing models include late-model variants of Gulfstream light-cabin types and the Dassault Falcon 2000 series, with buyer and charter demand often driven by cabin size, runway performance and operating economics. For this airframe—serial 5865, built in 2011—resale and maintenance considerations focus on CF34-3B engine maintenance status, avionics standardization (Collins Pro Line 4), and the configuration difference between the registry-listed 22-seat transport layout and typical executive interiors.
