This write-up covers airframe N546CG, a Cessna 550 Citation II built in 1991 with serial number 550-0686. The aircraft is owned by Coulson Aviation (USA) Inc, a corporate owner based in Portland, OR, US, and is registered in the US. Registry and ownership details indicate this airframe is operated from the owner’s Portland location; no other ownership transfers or registry actions are published in the provided data.

The airframe is fitted in the Citation II standard executive arrangement with a typical 6–8 place executive / 8-seat executive layout (Citation II standard), offering an eight-seat cabin when configured to its maximum executive seating. Operating from Portland, OR, the aircraft’s 1,900 nm range and 399 kt cruise speed make it suitable for medium-haul corporate missions and charter trips within the continental United States and to nearby international destinations. Maintenance considerations for this airframe would follow the Pratt & Whitney Canada JT15D-4 engine programmes and Cessna Citation II airframe support patterns; no specific avionics or unique interior modifications are published in the provided data.

The Cessna 550 Citation II occupies a light to light-medium business jet niche, offering transcontinental short-to-medium mission capability with a high operating ceiling of 43,000 ft and a cruise near 399 kts. Competing models typically include contemporaneous light jets that balance speed, range and operating costs; buyer and charter demand for airframes of this vintage often depends on maintenance history, engine programme status, and cabin condition. Resale and maintenance considerations for this specific airframe hinge on the documented owner/operator base in Portland and adherence to JT15D-4 engine maintenance and Citation II airframe service bulletins.
