N400MX

This article covers a single airframe, the business jet registered N400MX, a 2007 production example of the Beechjet 400A built by Raytheon Aircraft Company with serial number RK-509. The airframe is owned by RJB MANAGEMENT COMPANY INC, a corporation based in Moon Township, PA, US, and is registered in the US. The 2007-built airframe has established a straightforward ownership record with no publicized major registry actions beyond its corporate registration; current valuation is listed at $1,600,000, reflecting its market position and condition for a late-model light business jet.

The cabin of this airframe is operator-configurable but typically laid out with 7–9 executive seats in common Beechjet fashion, though the registered seating allowance is 10; the noted cabin entry describes a typical executive arrangement dependent on the operator. Avionics fit is not published in the supplied data, but mission profiles for this airframe generally include short to mid-range corporate trips and on-demand charter operations within the continental United States, taking advantage of a maximum cruise near 443 kts and a practical range of 1,693 nm. Based in Moon Township, PA for ownership records, maintenance considerations follow typical light business-jet schedules for the Beechjet 400A, including dual-engine preservation and JT15D-specific inspections.

The Beechjet 400A family occupies the light, fast-cabin business-jet niche, offering transcontinental capability for point-to-point corporate operations without the operating costs of larger jets. Competing models include other light jets of similar era and performance; resale and maintenance considerations for this 2007 airframe focus on engine life, avionics modernization, and corrosion/structural inspections typical of the platform. At a listed value of $1,600,000, this specific airframe represents an entry point for operators seeking speed and altitude performance (up to 45,000 ft) while accepting retrofit or avionics upgrade costs common to jets of its vintage.
