The Piper Aerostar (formerly Ted Smith Aerostar) is an American twin-engined propeller-driven executive or light transport aircraft, designed by Ted R. Smith. It was originally built by Ted Smith Aircraft Company, which after 1978 became part of the Piper Aircraft Corporation.

Design and development[edit]

Ted Smith flew the first Aerostar 600 in October 1967. It was a mid-wing cantilever monoplane powered by two wing-mounted Avco Lycoming piston engines, with a tricycle landing gear. It was fitted with luxury accommodation for six. Also produced, and the base of most of the subsequent models, was a version with a turbocharged engine, the Aerostar 601.

The Aerostar is one of the fastest twin piston engine aircraft produced,[dubious ][citation needed] with cruise speeds from 220 kt (408 km/h) for the earliest 600 models to 261 kt (483 km/h) for the later 700 models. Light construction, low drag and high powered engines also contribute to fast climb rates.

Operational history[edit]

The aircraft were originally built at Van Nuys in California, when in 1968 the company was bought by the American Cement Company. The acquisition was not a success and in 1969 the company was sold again to Butler Aviation, owners of Mooney Airplane Company. The new company was named Aerostar Aircraft Corporation and it was intended to move production to a Mooney plant at Kerrville, Texas. In 1971 Smith attempted to purchase the rights, and announced he would be building an all-new design that was better than the Aerostar when initial deals broke down.[1] In 1972 Ted Smith bought back all the rights to the aircraft and continue to manufacture Aerostars in Santa Maria, California. He also introduced the pressurized Aerostar 601P. The 601P had engines with higher-rate turbochargers to feed a cabin pressurisation system. Another variant was the stretched Aerostar 700 Superstar. In 1976 the company name was changed to the Ted Smith Aerostar Corporation. Ted Smith died in 1976.

In 1978 the company was taken over by the Piper Aircraft Corporation. It continued to build three variants (600A, 601B and 600P) and then re-introduced the 601P and 602P (sometimes known as the Sequoia). After discontinuing production of the non-pressurised models, Piper moved production to Vero Beach. The Aerostar was last built there in 1984.

The Aerostar type certificate and manufacturing documentation were sold in 1991 to Jim Christy and Steve Speer, who had been part of the Ted Smith Aerostar operation, and now operate Aerostar Aircraft Corporation in Hayden Lake, Idaho, providing maintenance and support of the aircraft and new R&D of its family of aircraft.[citation needed] Conceived with a jet-powered design structure by Ted Smith from the very beginning, the Aerostar Aircraft Corporation continued its R&D and finally completed Ted Smith's dream to convert the design into a twin fan-jet aircraft, with 6-seat (including 1 pilot) and its version of the 8-seat stretched variant.[citation needed]
