The Beechcraft Starship is a twin-turboprop six- to eight-passenger pressurized business aircraft produced by Beech Aircraft Corporation (now Beechcraft). ==Development== Development of the Starship began in 1979 when Beech decided to explore designs for a successor to its King Air line of turboprops that would fly faster and carry more passengers. The design was originated by Beechcraft in January 1980 as Preliminary Design 330 (PD 330). On August 25, 1982, Beech contracted with Scaled Composites to refine the design and build an 85% scale proof-of-concept (POC) aircraft.〔 One of the significant changes made to the design by Scaled Composites was the addition of variable geometry to the canard.〔Popular Science, June 1984, pp. 74-77, 143,〕 The POC aircraft first flew in August 1983.〔Warwick (p.24 )〕 This aircraft had no pressurization system, no certified avionics, and a different airframe design and material specifications than the planned production Model 2000. Only one POC was built and it has since been scrapped.〔 Prototypes were produced even as development work was continuing—a system demanded by the use of composite materials, as the tooling required is very expensive and has to be built for production use from the outset. Beech built three airworthy full-scale prototypes. NC-1 was used for aerodynamic testing〔 and was the only Starship equipped with conventional electro-mechanical avionics. NC-2 was used for avionics and systems testing and NC-3 was used for flight management system and powerplant testing.〔 NC-1 first flew on February 15, 1986.〔 The program was delayed several times, at first due to underestimating the developmental complexity and manufacturing learning curve of the production composite construction, and later due to the technical difficulties of correcting a pitch damping problem and developing the stall-warning system. By the end of development, the Starship had grown larger in cabin volume than the King Air 350 while having the same gross ramp weight of . Starship development cost $300 million.〔("The Starship Diaries" )〕 The first production Starship flew on April 25, 1989.〔("The Beech 2000 Starship 1" ). Airliners.net.〕〔("Starship History, Max E.
