N557SL

This article describes the individual airframe N557SL, a 2008-built example of the Cessna 680 Citation Sovereign with serial number 680-0199. The airframe was manufactured by Cessna Aircraft Company (Textron Aviation Inc.) and is currently registered in the United States to SLC DIVISION 4 LLC (an LLC based in Nashville, TN, US). The aircraft’s ownership is recorded under that LLC; any prior registrations or transfers are not published in the supplied data. As of the provided valuation, the airframe is estimated at $7,800,000, reflecting market condition and configuration for a late-2000s Sovereign in active service.

The cabin of N557SL is described as a typical 7–9-place executive layout with a forward galley and an aft lavatory, though the internal fit may vary by owner and this particular airframe is outfitted for up to 9 seats. Avionics are listed as Honeywell Primus Epic in the Sovereign-series baseline, which is the typical fit for this airframe; some aircraft in the model line have been retrofitted or optioned differently. Operationally, the Sovereign platform and this airframe are commonly used on short- to mid-range business missions consistent with a 2,829 nm range and cruise speeds near 459 kts, typically operated from business and corporate bases consistent with its U.S. registration. Maintenance considerations align with twin PW306C engine support and standard Sovereign-series scheduled inspections.

The Cessna 680 Citation Sovereign occupies the midsize-cabin, long-range business jet niche, offering transcontinental reach without step-to-large-jet costs. Competitors historically include aircraft in the midsize class offering similar speed and range; buyer demand typically centers on charter operators and corporate flight departments seeking a combination of runway performance and enclosed-cabin comfort. Maintenance and resale considerations for this 2008 airframe include engine support for the PW306C powerplant and avionics upgrade potential from the baseline Honeywell Primus Epic, factors that influence the reported $7,800,000 valuation.
