N508RZ

This airframe, N508RZ, is a 1988-built Cessna 650 Citation III with serial number 650-0164. The airframe is recorded in the U.S. registry and is registered to GEAUX FLIGHT LLC of Baton Rouge, LA, which is the current listed owner/operator. The type has been maintained through the typical retrofit and avionics variation paths common to late-1980s Citations, and the aircraft’s market valuation is recorded at $1,100,000, reflecting age and configuration. FAA registry entries note 12-seat certification for this airframe, a detail relevant to operations and charter or private transport configurations.

The cabin of N508RZ follows the Citation III-era typical fit: an executive club layout accommodating 8–10 passengers in the cabin with a forward refreshment/galley and a belted aft lavatory, while the FAA registry shows certification for 12 seats for this airframe. Avionics on many Citation IIIs of this vintage include Sperry/Honeywell SPZ-650 flight director/autopilot installations and Collins ProLine II-era communications and navigation equipment, though installed equipment varies by retrofit history and this airframe may reflect those typical configurations. Operational roles for N508RZ would commonly include medium-range corporate transport and on-demand charter flights out of its Baton Rouge base, leveraging a cruise of 418 kts and long-range capability near 2,038 nm. Maintenance considerations follow older high-performance turbofan standards, with attention to TFE731 series engine programs and avionics upgrade paths.

The Cessna 650 Citation III occupies a high-performance, mid-size business jet niche with high cruise speed and a 51,000 ft service ceiling, competing historically with contemporary offerings from Dassault and Gulfstream light/midsize lines. Demand for older Citation IIIs is driven by owner-operators and brokers seeking robust performance at lower acquisition cost, reflected in the $1,100,000 valuation for N508RZ. Resale and maintenance considerations center on engine program status for the Honeywell/Garrett TFE731 family, avionics retrofit investments, and cabin refurbishment to meet modern charter or corporate expectations.
