N660S

The airframe, registered as N660S, is a 2006-built Cessna 525A CitationJet CJ2+ with serial number 525A0305. It is owned by Alpine II LLC, an LLC based in Boulder, CO, US, which is the current operator/home base for the aircraft. The airframe’s entry in U.S. civil registers reflects ownership by a Colorado-based limited liability company, with no other publicized historic operators provided in the dataset. Valuation data lists the unit market value at $3,500,000, and the airframe is categorized as a fixed-wing multi-engine aircraft registered in the US.

The CitationJet CJ2+ configuration for this specific airframe supports seating for 8 occupants and is typically operated on short- to mid-range missions consistent with its 1,613 nm range and 413 kt cruise speed. Based at Boulder, Colorado under Alpine II LLC, the airplane’s operational profile would commonly include regional business travel and point-to-point charters within continental U.S. limits. The dataset does not publish a detailed cabin layout or avionics fit for this individual serial number, nor does it provide records of modifications; maintenance considerations for the type generally focus on Williams FJ44 series engine support and typical light-business-jet airframe inspections.

The airframe belongs to the Cessna 525A CitationJet CJ2+ family, a light business jet niche that balances lower operating costs with transcontinental short-haul capability. With twin Williams FJ44-3A-24 engines producing 2,490 lbf each and a service ceiling of 45,000 ft, the model competes with other light jets in its era for owner-operators and charter operators seeking efficient regional performance. Resale and maintenance considerations for this 2006 airframe include lifecycle support for the Williams engines, inspection and avionics upgrade history, and market demand reflected in the reported value of $3,500,000.
