certified by the U.S. Federal Aviation Administration had ever used it so extensively. Beech chose carbon fiber composite for its durability and high strength-to-weight ratio. According to Beech, the Starship weighs less than it would have if it were built from aluminum. Nonetheless, the empty weight of production aircraft exceeded the target by several thousand pounds. Beech studied several configurations before settling on a canard configuration in early 1980. As configured, the Starship is difficult to stall; the forward surface stalls before the main lifting surface, which allows the nose to drop and more-normal flight to resume. A traditionally located vertical tail would have transmitted propeller noise into the airframe. In its place, directional stability and control is provided by rudders mounted on the winglets. Because of this addition Beechcraft called the winglets "tipsails". Mounting the engines so that the propellers are facing rearward, pushing rather than pulling the aircraft, is done for the purpose of a quieter cabin, since the propellers are further back from the passengers and because vortices from the propeller tips do not strike the fuselage sides. However, the propellers are operating in a turbulent airflow in the pusher configuration (due to airflow past the wings moving aft in vortex sheets) and high-velocity exhaust gases are discharged directly into the propellers, producing more noise where they are than if the propellers had been in a tractor configuration. Flight instrumentation for the Starship included a 14-tube Proline 4 AMS-850 "glass cockpit" supplied by Rockwell Collins, the first application of an all-glass cockpit in a business aircraft. Operational history Beech sold only eleven Starships in the three years following its certification. Beech attributed the slow sales to the economic slowdown in the late-1980s, the novelty of the Starship, and the tax on luxury items that was in effect in the United States at the time. However, In an effort to stimulate demand, Beech began offering two-year leases on new Starships in 1991. The last Starship, NC-53, was produced in 1995. In 2003 Beechcraft said that supporting such a small fleet of airplanes was cost-prohibitive and began scrapping and incinerating the aircraft under its control. The aircraft were sent to the Evergreen Air Center located at the Pinal Airpark in Arizona for destruction. Beech worked with owners of privately owned Starships to replace their airplanes with other Beech aircraft such as the Premier I jet. In 2004, Raytheon sold
