N400MK

This airframe, registered as N400MK, is a 1999-built Raytheon / Beechcraft 400A (Beechjet 400A) with manufacturer serial RK-221. The certificate holder and listed owner is NORTH STAR COMPANIES INC of Mankato, MN, US, and the aircraft appears on the US registry in corporate ownership. The airframe's documented valuation is $1,600,000, reflecting market position for late-model 400A examples with typical equipment and maintenance status. Notable registry actions include its corporate registration and operational basing tied to the owner’s Mankato location.

The cabin of this Beechjet 400A is configured in a typical 7–9 passenger executive layout, with double-club seating commonly installed and a belted aft lav seat available, supporting up to 10 occupants when required. Avionics fit varies by retrofit, with common installations including Collins Pro Line or Collins FIS-series suites; this particular airframe is described as having a typical Collins fitment subject to individual upgrade history. Operationally the jet’s 443 kts cruise and 1,693 nm range suit short- to medium-range corporate missions, owner-operated flights, and charter work from the owner’s Mankato base. Maintenance considerations for this airframe center on legacy JT15D-5 engine support and ongoing avionics modernization to preserve utility and resale value.

The Raytheon / Beechcraft 400A (Beechjet 400A) family occupies the light business jet niche for high-speed, short-to-medium range missions with a 45,000 ft service ceiling and robust cruise performance. Competing models offer similar mission capability, and demand among corporate buyers and small charter operators remains linked to individual aircraft condition, avionics standardization, and engine life. Resale and maintenance considerations for this 1999 airframe include parts availability for JT15D-5 engines and the impact of avionics retrofits on marketability, factors reflected in the stated $1,600,000 valuation.
