N4S

The airframe bearing tail number N4S is a Cessna 525C Citation CJ4 built in 2016 with manufacturer serial number 525C0235. It is registered in the United States and is on the books to NASCOSTO SERVICES LLC, an LLC based in Edmond, OK, US. No prior owners or previous registries are recorded in the supplied data; the current ownership entry is the only documented registry action. Condition and valuation details are not provided in the source data.

This specific Cessna 525C Citation CJ4 is typically equipped with the Collins Pro Line 21 avionics suite as a standard 525C/CJ4 fit, supporting modern flight management, communications and navigation capabilities suitable for single-pilot or two-pilot operations depending on operator policy. The cabin layout for the model supports up to 11 seats and is configured for short- to mid-range executive and charter missions with a typical mission profile spanning regional city-pair hops up to the aircraft’s 2,165 nm range at cruise speeds near 451 kts. Based at the owner’s location in Edmond, OK, the airframe would be used for company transport, on-demand charter, or executive repositioning flights; no unique interior modifications or aftermarket amenities are listed in the supplied data. Routine maintenance considerations follow the CJ4 fleet practices for the twin Williams FJ44-4A powerplants and Pro Line 21 avionics, though specific maintenance status for this serial is not provided.

The Cessna 525C Citation CJ4 occupies the light to lower midsize business jet niche, prized for high cruise speed, transcontinental range within its class, and efficient Williams FJ44-4A engines producing 3,621 lbf each. Competitors in its class include light-cabin jets from Embraer and Learjet variants that offer similar seat counts and mission flexibility. Buyer and charter demand for well-equipped CJ4s tends to favor airframes with current avionics like Collins Pro Line 21 and clean maintenance records; resale and maintenance considerations center on engine time, avionics upgrades, and interior refurbishment history, none of which are specified for this individual airframe.
