N755TS

The airframe N755TS is a 2014-built Cessna Citation CJ4 (525C) with serial number 525C0173, manufactured by Cessna Aircraft Company (Textron Aviation). The aircraft is owned by CSI TUNNEL SYSTEMS LLC (an LLC based in Hudson, NH, US) and carries US registration. This specific airframe is representative of late-production CJ4s and is valued at approximately $7,500,000 in current assessments. Notable registry action: listed on the U.S. civil aircraft register under the owning LLC, and no other public ownership transfers are recorded in the supplied data.

This airframe is configured with a typical CJ4 executive interior accommodating an 8–10 passenger executive club layout, featuring a forward refreshment center and a belted aft lavatory, and is certificated up to 11 seats. The avionics fit for the series on this airframe is the Collins Pro Line 21 suite, providing modern integrated flightdeck functionality common to CJ4s. Typical missions for this configuration include short- to mid-range business or corporate charters and owner-flown transport within the aircraft’s 2,165 nm ferry range at cruise speeds around 451 kts, operating from the owner’s New Hampshire base for continental U.S. missions. Maintenance considerations for this specific CJ4 reflect standard light-jet practices for Williams FJ44-4A engines and Pro Line 21 avionics support networks.

The Cessna Citation CJ4 (525C) occupies the light-corporate jet niche with a combination of high cruise speed, transcontinental short-range capability, and a high practical ceiling of 45,000 ft. Competing models include other light-cabin jets that trade range, cabin size, and operating cost; buyer and charter demand typically favor CJ4s for owner-operators and charter operators requiring eight to eleven seat flexibility. Resale and maintenance considerations for this airframe hinge on engine maintenance cycles for the Williams FJ44-4A powerplants, avionics support for the Collins Pro Line 21, and the airframe’s documented status under CSI TUNNEL SYSTEMS LLC.
