N421MP

This entry covers airframe N421MP, a 2009-built Cessna 525B Citation CJ3 with manufacturer serial number 525B0328. The aircraft is registered in the United States and is owned by KATEYS PLANE LLC, an LLC based in Greenwich, CT, US, reflecting a single corporate ownership record in available data. The airframe is a late-2000s Citation CJ3 delivery and is noted in registry listings with a market valuation of $5,995,000 at the time of the provided appraisal. No interim operators or additional registry actions are published beyond the listed corporate ownership and valuation.

The airplane is configured in a typical executive layout with two crew and six passenger seats, described as a 2+6 cabin arrangement that supports small-group business transport and owner-flown operations. The cockpit is equipped with a Collins Pro Line 21 avionics suite, which provides integrated flight management, communications and navigation capabilities common to light business jets of its vintage. With a maximum cruise near 416 kts and a ferry range of about 2,040 nm, operational missions for this airframe typically include medium-range point-to-point business travel and regional charter work from its Greenwich, Connecticut base. Maintenance considerations for this specific airframe center on Williams FJ44 powerplant support and avionics lifecycle updates typical for a 2009 CJ3, with no unique modifications or refurbishments published in the supplied data.

The Cessna 525B Citation CJ3 occupies the light-cabin, light-jet niche as a high-utilization business aircraft offering transcontinental-influenced range for its class. Competitors in the market include other light jets that balance operating economics and cabin comfort; the CJ3’s cruise performance and 45,000 ft ceiling keep it competitive for charter and owner-operator demand. Resale and maintenance factors for this airframe hinge on the condition of the Williams FJ44-3A engines and the Collins Pro Line 21 avionics suite, both determinative for marketability and the listed valuation of $5,995,000.
