N618JJ

This airframe, registered as N618JJ, is a 1999-built Bombardier CL-600-2B16 Challenger 604 carrying serial number 5440. The airframe is recorded in the U.S. registry and is owned by JJ CHALLENGER 620TM LLC, an LLC based in Wilmington, DE, US. The record lists a typical executive configuration but notes that the registry allows up to 22 seats depending on interior fit; no separate operator name or base beyond the registered owner is published. Maintenance and valuation commentary in public records is not published for this specific tail, though the Challenger 604 family generally commands steady demand in the large-cabin used business jet market.

The airframe is configured in the typical executive layout for the model, supporting a 10–12 passenger executive cabin as standard while the registry documents the airframe can accommodate up to 22 seats depending on interior configuration. The baseline avionics fit for the platform is the Collins Pro Line 4 suite, although the entry for this airframe notes that operator-specific upgrades are possible and commonly performed. Typical missions for the airframe type include transcontinental and high-end charter operations, with the listed range of 4,033 nm supporting long overwater and intercontinental city-pair payloads at cruise speeds near 459 kts. Specific unique amenities or maintenance history for this serial are not published in the provided data.

The Bombardier CL-600-2B16 Challenger 604 occupies the large-cabin, long-range business jet niche, offering wide cabin comfort and transcontinental capability for corporate and charter operators. It competes with similar large-cabin types in the late-1990s production era; buyers typically consider the CF34-3B engine type, avionics baseline such as Collins Pro Line 4, and interior configuration when evaluating maintenance and resale value. Older airframes like this 1999-built 5440 are commonly evaluated on avionics upgrades, interior refurbishment, and engine program status when determining marketability and operating economics.
