N631CB

This entry covers airframe N631CB, a 2008-built Cessna 680 Citation Sovereign with serial number 680-0227. The aircraft is recorded as owned in co-ownership by KMAC AIRCRAFT COMPANY LLC, based in Lafayette, LA, US, and is registered in the US. The airframe is representative of original Sovereign production examples and carries an estimated market value of $7,200,000; registry notes and operational history reflect standard corporate use and localized basing in Lafayette rather than full-time charter operations. The co-ownership arrangement is a notable ownership structure for this airframe and informs shared operational and maintenance responsibilities.

The cabin for this Sovereign is fitted in the typical 8–9‑place executive layout, featuring a double‑club seating arrangement, a forward galley and an enclosed lavatory while retaining a published maximum capacity of 12 passengers. Avionics aboard this airframe are consistent with original Sovereign production and therefore typically include the Honeywell Primus Epic suite; later Sovereign+ trend upgrades such as the Garmin G5000 or PW306D engine variants are not indicated for this serial. Operationally the airframe suits medium‑range corporate missions out to its 2,518 nm capability and high‑speed cruise regime near 446 kts, with typical use profiles including point‑to‑point business travel and regional executive transport from its base in Lafayette. Maintenance considerations follow the Pratt & Whitney PW306C engine program and Honeywell avionics support practices customary to the model.

The Cessna 680 Citation Sovereign occupies a mid‑to‑large light business jet niche, offering trans‑regional range and high single‑engine redundancy with twin PW306C powerplants. Competing models in its era addressed similar mission profiles, and demand for this configuration remains driven by buyers seeking a mix of cabin comfort for up to nine passengers and cruise performance near 446 kts. Resale and maintenance considerations for this airframe center on engine program status, avionics configuration (original Honeywell Primus Epic), and documented ownership/maintenance history under co‑ownership with KMAC AIRCRAFT COMPANY LLC, all factors that bear on marketability at its approximate value of $7,200,000.
