The 400A has undergone vast design improvements from the original 400. It is mainly constructed of aerospace light alloys. The fuselage’s new fuel tank located under the floor allows more cabin space.
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 fully breathable 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 makes for a more enjoyable and quieter cabin environment.
