N674TB

This entry covers the specific airframe N674TB, a Canadair Challenger 600S (CL-600-1A11) built in 1982 with manufacturer serial number 1074. The airframe is registered in the US and carries an estimated market valuation of $1,000,000, reflecting its age and original systems fit. Ownership timeline and operator/home base details: Not published. Notable registry actions: Not published; condition highlights indicate an airframe reflecting original analog avionics unless later upgraded.

The cabin of N674TB is configured in a typical 11-place executive layout: a wide cabin with a forward galley and aft lavatory and a mix of club and conference seating commonly found on Challenger 600-series corporate transports. Avionics for this airframe are the original analog fit, notably the Sperry SPZ-600 flight guidance and SPZ-650 autopilot combined with Collins Pro Line 1 communications and navigation equipment; many airframes later receive avionics upgrades and this airframe’s current avionics status is not published beyond the original fit. Typical missions for an aircraft with this configuration and performance are medium-range corporate flights or charter legs within the transcontinental band enabled by a 2,900 nm radius, operating from operator bases equipped to support older turbofan types. Maintenance considerations for this specific airframe would include airframe-age inspections, engine support for Honeywell ALF 502L units, and potential investment in avionics modernization to meet contemporary airspace requirements.

The Canadair Challenger 600S (CL-600-1A11) occupies the large-cabin, medium-range corporate jet niche of early 1980s design, offering a wide cabin and transcontinental capability relative to contemporaries. Competing models historically include other large-cabin types of the era; buyer demand for individual airframes such as N674TB often centers on price-conscious purchasers willing to accept legacy analog systems or to invest in upgrades. Resale and maintenance considerations emphasize engine support for the ALF 502L, structural and systems corrosion/age management, and the potential cost of avionics retrofits to sustain operational utility in regulated airspace.
