Beechjet 400aThe History behind this Exclusive Jet
Development of the Beechjet 400 first showed up on the radar in 1985 after Mitsubishi sold rights of the Diamond II executive jet along with numerous incomplete airframes to Beechcraft. A year later, Beech announced production of their own model, the Beechjet 400, and then finally the 400A in 1989. The aircraft was in production for 17 years (1986-2003), Beech built 421 of the 400 and 400A aircraft before eventually being acquired by Raytheon. However, the Beechjet series, namely the 400A, still remains a strong and successful competitor in the entry-level business jet market.
Although the 400 was a fine aircraft, Beech made leaps and bounds with its light private jet: The Beechjet 400A is a more efficient, spacious and comfortable jet compared to its predecessor, the 400. The 400A boats a greater cabin volume, contains a rear lavatory, improvements in performance include an increased in payload, greater operating ceiling and landing weight, as well as additional 150lb of fuel storage and improved cabin sound proofing.
Beechjet 400A receives its power from two Pratt and Whitney of Canada JT15D-5 turbo-fan engines. Each engine produces 2,900 lbs of thrust and has an inspection interval of 3,500 hours.
These engines, along with unique design features, allow the 400A to travel around 1,500 nautical miles at a speed of mach 0.78. Its maximum speed is 446 knots, another improvement from its predecessor. The 400A has a maximum payload of 2,172 lbs and a maximum flight ceiling of 45,000 feet. 53 cubic feet of baggage space is an additional amenity.
Comfort & Size
The cabin of the 400A is more spacious thanks to the aforementioned refinements. Carrying 7 or 8 passengers and a crew of two, the interior dimensions measure: 15.6 ft long, 4.8 ft high and 4.9 ft wide.
Passengers enjoy seats that swivel up to 180 degrees. A cabin baggage area and refreshment cabinet have been added. Newly located engine mounts and the addition of sound-dampening materials allows for a much more enjoyable and quieter cabin environment.
The 400A employs the Collins Pro Line 4 avionics system. The system includes the Collins FCS-850 digital flight control system, Collins FMS-850 flight management system, EFIS (EFD-871), Collins MFD-871 (single multifunction display), Collins WXR-840 color weather radar, and Collins ALT-55B radio altimeter and Rosemount air data system. The 400A was notably the first aircraft to be certified with such an
advanced cockpit suite.
The 400A has undergone vast design improvements from the original 400. It is mainly constructed of aerospace light alloys. Three separate fueling ports (one in each wing and one in the fuselage) combine to hold 4,911 lbs of fuel. The fuselage’s new fuel tank located under the floor allows more cabin space. The aircraft is designed to consume fuel in the fuselage compartment first to steady the wings’ bending moment. Additionally, the brakes incorporate anti-skid logic to allow a greater maximum landing weight.

With such strong design features, it is not surprising that the Beechjet 400A serves as the basis for the military T-1 Jayhawk tanker and transport aircrew trainer. 180 of the T-1 Jayhawks were delivered between 1992 and 1997 for military training. The 400A has been continuously redesigned, and has now evolved into Raytheon’s successful Hawker 400. Despite its age, the original iteration of the 400A still remains a strong contender in its class, and is ideal for corporate or individual travel.
