The Beechcraft Beechjet 400A is an upgraded variant of the original Mitsubishi MU-300 Diamond, a design that Beechcraft acquired in the mid-1980s. Following modifications and enhancements, Beechcraft introduced the 400A in 1990 as a more capable light jet tailored for corporate and charter use. Compared to the earlier 400 model, the 400A features significant avionics improvements, an upgraded interior, and increased payload capabilities.
Production of the Beechjet 400A began in 1990 and continued until 2003, when the design evolved into the Hawker 400XP under Raytheon’s Hawker Beechcraft division. The 400A offered refinements such as a redesigned cabin layout for increased passenger comfort, digital pressurization, and enhanced soundproofing. Its cabin is typically configured to seat up to 7 passengers in a business layout, excluding crew.
Powered by two Pratt & Whitney JT15D-5 engines, each producing 2,900 pounds of thrust, the Beechjet 400A achieves a maximum cruise speed of 447 knots and a maximum range of approximately 1,500 nautical miles. It has a maximum takeoff weight (MTOW) of 16,100 pounds and requires approximately 3,900 feet of runway for takeoff at standard conditions. The aircraft's cabin volume totals around 305 cubic feet, with a flat floor and squared-oval cross-section that optimize usable space.
With its combination of speed, comfort, and relatively low operating costs, the Beechjet 400A remains a popular choice in the pre-owned jet market, valued for its efficiency and proven airframe design.
