The Beechjet 400 is a small twin-engine jet corporate aircraft. Initially designed and built by Mitsubishi, it has been further developed and updated by the Beech Aircraft Company, now part of Hawker Beechcraft. It is a small, low-winged twin-turbofan aircraft of all metal construction, flown by a crew of two pilots and accommodating eight passengers in a pressurised cabin. Its wings use a computer designed, supercritical airfoil in order to minimise drag.
