N611AZ

This airframe, registered as N611AZ, is a 2005-built Bombardier Challenger 604 (CL-600-2B16) with serial number 5637, manufactured by Bombardier Inc.. The jet is registered in the United States and is owned by the Delaware corporation PALOMA & JOAN LLC, located in Dover, DE, US; its registration and corporate ownership record indicate standard U.S. registry status without published incident history. The type is categorized as a fixed-wing multi-engine business jet and carries an estimated market value of $6,300,000, reflecting its age and common 604-series equipment fit. Entered service in 2005 and filed under corporate ownership in Delaware are notable points in this airframe’s administrative timeline.

The subject Challenger 604 is equipped with a typical executive interior configured for ten passengers in a forward galley, club seating arrangement, and an aft lavatory, while its certification permits seating up to 22 for higher-density operations. Avionics are the series-common Rockwell Collins Pro Line 4, supporting the navigation, communication and flight management capabilities expected of mid-2000s Challengers and enabling long-range, single-pilot-augmented operations within corporate flight departments or charter operators. Typical missions for this airframe include transcontinental and transoceanic executive transport within its 4,000 nm range and cruise at approximately 459 kts, operating from a corporate base consistent with the owner’s Dover, DE, location. Maintenance considerations align with CF34-3B engine support cycles and the 604 airframe’s avionics commonality, which can simplify parts and avionics support but still requires attention to aging systems and accessory overhaul schedules.

The Challenger 604 family occupies a midsize, long-range business jet niche offering robust payload-range capability and a high, comfortable cabin relative to light jets. Competing models in its era include late-model Gulfstream G150 variants and the Bombardier Challenger 300 in different payload/range trade-offs. Ongoing buyer and charter demand tends to favor 604 airframes with Pro Line 4 avionics and well-documented maintenance histories; resale value for a 2005 airframe like N611AZ is influenced by engine cycles on the CF34-3B pair, interior condition, and the presence of updated avionics or structural inspections. Maintenance and resale considerations are typical for mid-2000s business jets: engine shop visit status, supplemental inspection compliance, and cabin refurbishment needs directly affect marketability and the listed $6,300,000 valuation.
