N550HC

The airframe bearing tail number N550HC is a 1986-built Cessna S550 Citation SII, serial S550-0116, produced by Cessna (Textron Aviation). The airframe is currently owned and operated by DOS AMIGOS TRANSPORT LLC, an Austin, Texas–based limited liability company, and is registered in the US. The aircraft’s registry reflects its corporate ownership and Austin home base, and it carries an assessed market value of $800,000 consistent with its vintage and configuration. Given its 1986 build year and twin JT15D engines, the airframe typically presents maintenance and inspection profiles associated with mature Citation SII examples.

The cabin on this airframe is configured for 7 seats, consistent with light business jet layouts intended for small corporate teams or charter missions. Specific avionics fit and interior finish details for this serial are not published in the supplied data; operators of this airframe type commonly adapt interiors to mixed executive/utility roles. Typical mission profiles for N550HC include short- to medium-range corporate hops and on-demand charter flights within the 1,700 nm performance envelope from its Austin base. Maintenance considerations for this airframe include lifecycle management of the Pratt & Whitney Canada JT15D-4B turbofans, aging airframe corrosion and systems inspections, and adherence to type-specific service bulletins applicable to late-1980s Citation SIIs.

The Cessna S550 Citation SII occupies the light twin-jet niche for economical, short- to medium-range business transport, offering cruise speeds around 322 kts and high-altitude capability to 43,000 ft. Contemporary competitors historically include early-model Learjets and the small Beechjet/Mitsubishi Diamond derivatives; market demand is driven by buyers seeking low-hour, well-maintained vintage Citations for cost-conscious operations. Resale and maintenance considerations for this specific 1986 airframe emphasize engine life, structural integrity, and avionics modernization when assessing long-term value against the reported $800,000 valuation.
