N650SG

This article covers airframe N650SG, a factory-built Cessna 650 Citation III completed in 1990 with serial number 6500191. The airframe is registered in the United States and is owned by MERLIN ONE AIRCRAFT LLC of San Antonio, TX, US, which appears as the current listed owner and operator/home base. The airframe’s entry on the civil registry and any notable transfers or liens are not detailed here; the aircraft is described in available records with a market valuation of $900,000, reflective of its age and configuration. Condition highlights indicate a production-era Citation III airframe equipped for executive transport with typical long-range capability for its class.

The cabin conforms to a model-typical executive layout, described as a 6–9 place arrangement in operational practice, with a stand-up cabin, an enclosed aft lavatory and a forward refreshment center. Specific avionics fitment for this individual airframe is not published in the supplied data; operationally the airframe’s performance—high cruise speed and long-range capability—supports transcontinental and cross-country business missions and charter work out of its San Antonio base. Typical missions for this airframe include medium- to long-range executive transport and on-demand charter, where the combination of speed, altitude capability and a small executive cabin yields schedule flexibility and access to higher-weather-clearance cruise levels. Maintenance considerations for a 1990-built Citation III often focus on airframe fatigue inspections, interior refurbishment, and engine TFE731 life-limited component programs.

The Cessna 650 Citation III family occupies a higher-performance niche among late-20th-century business jets, offering elevated cruise speeds and a 51,000 ft ceiling that enable efficient, high-altitude routing. Competing aircraft in the vintage super-midsize category typically feature similar mission profiles but may differ on range and cabin size; buyer and charter demand for older Citation IIIs tends to be driven by price-conscious operators seeking high performance at lower acquisition cost. Resale and maintenance considerations for this airframe are influenced by its 1990 manufacture date, cumulative hours/cycles and the TFE731 engine maintenance track record; the listed value of $900,000 reflects market depreciation and the cost of required continuing maintenance and potential refurbishment.
