N173AA

This airframe, registered as N173AA, is a 1980-built example of the Cessna 550 Citation II with serial number 550-0234. It is owned by INTERSTATE HEALTH SOLUTIONS LLC, a corporate owner based in Orlando, FL, US, and appears in U.S. civil aircraft registry records under that corporate registration. The airframe is identified in listings as having a forward lav configuration specific to this serial, and available valuation information lists a market value of $740,000. Maintenance and equipment notes in public listings indicate a mix of legacy avionics with at least one modern touchscreen navigator, reflecting incremental upgrades rather than a full panel retrofit.

The cabin of this Citation II is typically arranged in an 8-place executive double‑club layout with a small forward refreshment center and a belted aft lav, and listings for this specific airframe indicate a forward lav configuration. Avionics reported for this airframe include a Garmin GTN‑750 touchscreen navigator alongside legacy Collins and Sperry radios and autopilot components (reports cite Collins ADF‑60 and Sperry SPZ‑500 equipment). Typical mission profiles for this airframe, given its cruise speed and 1,900 nm range, would be short‑ to mid‑range executive transport and corporate shuttle flights operating from its operator base in Orlando, FL. The mix of modern and legacy avionics suggests maintenance considerations focused on avionics integration and support of older Collins/Sperry line-replaceable units alongside Garmin-supported navigation.

The Cessna 550 Citation II occupies a light corporate jet niche offering moderate speed, range and low‑cost operation relative to larger cabin jets. Competing models historically include other light-cabin jets with similar range and capacity; demand is often driven by owner-operators and small charter operators seeking economical short‑to‑mid‑range capability. For this 1980 airframe, resale and operational considerations center on airframe age, condition, maintenance history, and the cost to modernize avionics; the listed value of $740,000 reflects those lifecycle and market factors.
