N53DF

This entry covers airframe N53DF, a Bombardier Challenger 604 (CL-600-2B16) built in 2001 with manufacturer serial number 5507. The aircraft is U.S. registered (US) and carries an estimated market value of $5,000,000. Ownership timeline, operator/home base and specific registry actions are not published for this airframe; no notable public ownership events are recorded in the provided data. Condition highlights are limited to the supplied valuation and factory fit data.

The cabin for this airframe is described as a typical executive layout with a 10‑place executive configuration commonly installed, while certification allows up to 22 seats depending on configuration. Avionics fit for the type and this installation is listed as the Rockwell Collins Pro Line 4, which may be an OEM option or a retrofit depending on the aircraft’s maintenance and modification history. Typical missions for a Challenger 604 of this specification include transcontinental and long-range charter or corporate transport within the listed 4,033 nm range and at cruise speeds near 459 kts; specific operator base and route history for N53DF are not published. Maintenance considerations follow the Challenger 600-series common practices for twin CF34-powered business jets and take into account executive cabin configurations and avionics retrofits.

The Bombardier Challenger 604 (CL-600-2B16) occupies a midsize long-range business jet niche, offering transcontinental capability with twin General Electric CF34-3B engines and a high‑ceiling capability of 41,000 ft. Competing models in its class include later Challenger variants and other large-cabin midsize jets with similar range and cabin capacity. Buyer and charter demand for a 2001 Challenger 604 with Pro Line 4 avionics and a 10-place executive layout will reflect airframe condition, maintenance status, and total time on serial 5507; resale considerations center on avionics level, interior refurbishment, and engine cycles.
