Model & Market Context

This airframe, registered as N550NT, is a 1980-built Cessna 550 Citation II bearing serial number 550-0123. The airframe is recorded as owned by ALLIED ASSET MANAGEMENT LLC, an LLC based in Oklahoma City, OK, US, and operates under a US registration. Publicly reviewed records do not publish an extended ownership timeline or recent registry actions for this specific serial; the available data highlights the current LLC ownership without further transfer history or condition appraisals. No independent valuation or condition report is provided in the supplied data.

The cabin for this airframe is described as the typical executive Citation II layout accommodating seven to eight passengers, with a forward galley and common club/divan seating configurations; the specific fit for N550NT is not published in the reviewed public records. The aircraft’s twin JT15D-4 turbofan installation, combined with the airframe’s certified ceiling of 43,000 ft and a cruise near 369 kt, positions it for short- to mid-range executive transport and business charter missions up to approximately 1,900 nm. Operator base activity and detailed avionics or interior amenity lists for N550NT are not provided in the supplied dataset, and maintenance status or particular equipment differences for this serial are likewise not published.

The Cessna 550 Citation II family occupies the light business jet niche with a balance of speed, range and operating economy suitable for regional corporate missions and air charter operators. Competitors in its era and market segment include other light-cabin business jets offering similar payload-range trade-offs. For airframes of the 1980 vintage, prospective buyers and operators commonly weigh engine overhaul status, avionics upgrades, and interior refurbishments in resale value and continued operational use; the twin JT15D engines and eight-seat typical cabin layout are central considerations for maintenance planning and mission suitability.
