N575SG

This airframe, N575SG, is a 1985-built Cessna Citation S/II (S550) with manufacturer serial S550-0064. The aircraft is currently owned by OSAGE AVIATION LLC, an LLC based in Yates Center, KS, US, and carries United States registration. The airframe’s status and notable registry filings are limited in the available data, but its reported market valuation is $856,000, reflecting its age and configuration. Ownership by a single-entity LLC suggests private or on-demand corporate operations from a regional base in Kansas.

The cabin is described in the executive 8‑place typical S/II layout, commonly featuring club seating and often fitted with a divan, consistent with corporate shuttle or owner-flown missions. Specific avionics for this airframe were not located; common fitments across the model run include Collins Pro Line integrated systems or legacy analog suites, so equipment variation should be expected. With a cruise speed of 403 kts and a range near 1,998 nm, mission profiles typically include short‑to‑mid‑range business trips, regional charter work, and owner/operator point‑to‑point travel from its Kansas home base. Maintenance considerations for this particular airframe reflect its mid-1980s manufacture date and JT15D-4 powerplants, which may require attention to engine life-limited components, aging‑airframe inspections, and avionics modernization when deployed in commercial or high-utilization roles.

The Cessna Citation S/II (S550) occupies a light corporate jet niche characterized by efficient twin JT15D engines, transcontinental‑adjacent range for light jets, and a pressurized executive cabin for up to eight passengers. Competing models in its era and market segment include early Learjet 31/35 variants and small Dassault or British Aerospace light jets; buyers often value low operating costs and simple systems over ultra‑long range. Resale and maintenance considerations for this 1985 airframe hinge on total time, engine cycles, and avionics fitment; the reported valuation of $856,000 reflects those lifecycle and marketability factors.
