N404MS

This entry concerns airframe N404MS, a Beechcraft 400A built in 2000 with manufacturer serial RK-283. The jet was manufactured by Raytheon Aircraft Company (Beechcraft) and is registered in the US, currently owned by the corporation AIR 121 LLC based in Jacksonville, FL, US. The airframe’s public record reflects a corporate ownership structure rather than individual ownership, and no additional notable registry encumbrances or historic incidents are published in the supplied data. Condition and valuation details are not published in the provided dataset.

The cabin for N404MS conforms to the Beechcraft 400A’s typical executive layout, supporting a 6–10 passenger configuration and commonly fitted as a 7-seat executive interior on many examples. Avionics fit for the airframe is cited as the Collins Pro Line 4, a common retrofit/fitment for the type that supports typical corporate mission equipment and flight management systems. Operated from a Jacksonville, Florida corporate base under AIR 121 LLC, the aircraft is typically deployed on short- to medium-haul business missions that leverage its high cruise speed and transregional range. Maintenance considerations for this individual airframe would follow Beechcraft 400A practices and the recommissioning and avionics support paths typical for Pro Line 4-equipped light business jets.

The Beechcraft 400A (Beechjet 400A) family occupies the light-to-mid-size business jet niche, offering high cruise speeds (here 449 kts) and a 45,000 ft service ceiling conducive to efficient point-to-point corporate operations. Competing models in the era and market segment include other late-1990s/early-2000s light business jets with similar seating and range profiles; demand is typically driven by fractional owners, small corporates, and charter operators. Resale and maintenance considerations for this airframe are influenced by engine type (JT15D-5), avionics fitment (Collins Pro Line 4), and condition tied to corporate operation and upkeep standards.
