N52KX

This article describes airframe N52KX, a Cessna 525 CitationJet (Citation CJ1) manufactured by Cessna (Textron Aviation) and completed in 1998, serial 525-0287. The airframe is registered in the US and is recorded as owned by ZB AIR LLC, a corporation based in Broken Arrow, OK, US. Public listings and registry entries note a typical CJ1 executive interior with eight seats and broker material highlights avionics upgrades and EFIS elements; the airframe’s advertised market valuation is $1,395,000. Broker listings also report supplemental type certification work on cockpit navigation equipment and ADS‑B transponder installation.

The aircraft is configured in an executive cabin described as a 6–8 place layout, with registry and broker listings emphasizing an eight‑seat arrangement consistent with typical CJ1 executive interiors. Avionics reported for this specific airframe include a retrofit navigation package with Dual Garmin GTN 750s (STC), Garmin GTX ADS‑B transponders (GTX3xx family) and Honeywell EFIS elements as noted on the broker listing. Typical mission profiles for this airframe match the light business jet role—short to medium‑range executive transport within the aircraft’s 1,550 nm range and cruise speed near 389 kts—operating from regional bases such as its owner’s home in Broken Arrow, OK, US. Maintenance considerations for this airframe reflect the mature CJ1 fleet age (built 1998) and the presence of aftermarket avionics STC work.

The Citation CJ1 family occupies the light, entry‑level business jet niche, offering modest capacity, efficient Williams FJ44 series turbofans and transcontinental capability suitable for owner‑operators and charter operators. Comparable aircraft in the market include other light jets targeting short to mid‑range missions; resale and maintenance considerations for this airframe center on age, engine hours, and documented avionics retrofits—factors that influence the listed $1,395,000 valuation and buyer interest in modernized cockpit equipment.
