off its entire inventory of Starship parts to a Starship owner for a fraction of its retail value. Variants Model 115 Conceptual 85% scale prototype, one built by Scaled Composites. Model 2000 Initial production version. 20 produced including three pre-production airworthy prototypes. Model 2000A Beech did not serialise the 2000A as a distinct model and it was not issued a new FAA type certificate. The final 2000A configuration had tuning-fork-type noise dampers and improved insulation to reduce cabin noise and redesigned exhaust stacks for more efficient engine airflow. Stall strips placed on the front wing to enhance stall behavior were removed. Elimination of the stall strips reduced stall speed by up to , which allows the 2000A to takeoff from shorter runways. The 2000 had standpipes in the fuel tanks to artificially limit fuel capacity so the aircraft would meet a target payload weight. The standpipes were removed in the 2000A, increasing fuel capacity by . Both the maximum ramp weight and takeoff weight were increased by and zero fuel weight was increased . Beech produced a kit to upgrade serial numbers NC-4 through NC-28 to 2000A specifications. Aircraft on display Several Starships have been donated to museums since the decommissioning program began. The Kansas Aviation Museum received the first donated aircraft, NC-41, in August 2003 and the Beechcraft Heritage Museum in Tullahoma, TN, received the second donated aircraft, NC-49, in September 2003. NC-42 was donated to the Museum of Flight in Seattle, WA, and is currently on loan to the Future of Flight at Paine Field in Everett, WA. NC-27 was donated to Evergreen Aviation & Space Museum in McMinnville, Oregon in late 2003 and is currently on static display. NC-23 is on Airline Row at the Pima Air & Space Museum. NC-6 is on display in Liberal, KS, at the Mid-America Air Museum. Aircraft NC-28 is on display at the Queensland Air Museum, after it was used by the Queensland Institute for Aviation Engineering in Caloundra. Aircraft NC-14 is on display outside at the Southern Museum of Flight. Surviving aircraft , nine Starships hold an active registration with the FAA. Three Starships are registered in Oklahoma (NC-29, NC-35 & NC-45), one in Texas (NC-50), one in Colorado (NC-51), and four are registered to Beechcraft in Wichita, Kansas (NC-2, NC-8, NC-19 & NC-24). NC-51 was used as a chase plane during the re-entry phase of Burt Rutan's SpaceShipOne. In
