N66MC

The airframe bearing tail number N66MC is a 1981-built Cessna 550 Citation II with serial number 550-0239. The airframe is registered in the United States and is owned by Mcs2 Holdings LLC, a corporation based in Helena, MT, US. The aircraft’s public record indicates ownership by a corporate entity rather than an individual operator, and registry entries preserve its corporate registration and home-base association with Helena, Montana. Condition and valuation notes are not published in the supplied data.

This specific airframe is fitted with a nine-place executive cabin in a 9-place executive layout, providing seating for up to 9 occupants in a typical corporate interior. The commercial listing for this airframe indicates an avionics upgrade to a Garmin GNS-530, reflecting a partial modernization of its navigation and situational-awareness suite relative to original equipment. Typical mission profiles for the aircraft type and this configuration would include short- to medium-haul corporate or charter flights across the continental United States within its 1,900 nm range and at cruise speeds near 400 kts. Maintenance considerations for this airframe would follow standard Citation II practices for 1981-vintage airframes and JT15D-4 turbofan powerplants, with operator-based upkeep under corporate ownership.

The Cessna 550 Citation II occupies a light-medium business jet niche offering transcontinental capability with economical single-pilot or two-pilot operations depending on outfitting, and a certified ceiling of 43,000 ft. Competing models in its vintage class include earlier Learjet and Hawker variants as well as other Citation family types; buyer and charter demand for well-maintained Citation IIs typically centers on cost-conscious corporate operators seeking a balance of range, speed, and operating economics. For resale and maintenance, attention is generally paid to engine times on Pratt & Whitney JT15D-4 units, avionics upgrades such as the Garmin GNS-530, and documentation consistent with corporate ownership.
