The Schweizer Aircraft Corporation was an American manufacturer of sailplanes, agricultural aircraft and helicopters located in Horseheads, New York. It was incorporated in 1939 by three Schweizer brothers (Paul, William, and Ernest), who built their first glider, the SGP 1-1, in 1930. Previously the oldest privately owned aircraft company in the United States, Schweizer was acquired by Sikorsky Aircraft Corporation of Stratford, Connecticut in 2004, and became a diversified aerospace company. Schweizer Aircraft ceased operations in 2012. It was sold to Schweizer R.S.G. in 2018 and production lines were opened again in Fort Worth, Texas. The company was producing three helicopter models in 2021. History The company grew out of the Mercury Glider Club which produced the first two Schweizer gliders in the Schweizers' barn. The company was originally called the Schweizer Metal Aircraft Company. Attorney Bob McDowell indicated to the Schweizers that they should move their manufacturing operation out of their father's barn and relocate to the Elmira, New York area. The Schweizers received the suggestion positively as they needed more space to produce gliders, but they had no money with which to make the move. McDowell convinced Elmira Industries Inc, the local business development corporation, to provide space for the Schweizers on the second floor of the Elmira Knitting Mill Building in return for stock in the company. This resulted in the Schweizer Metal Aircraft Company becoming the Schweizer Aircraft Corporation, with a sale of shares to Elmira Industries, local businessmen and soaring pilots. Helicopters Schweizer primarily produced light, piston-engined helicopters for use in utility and flight-training roles. The Schweizer 300CBi, originally designed and manufactured by Hughes aircraft as the Hughes 269 for the United States Army, is one of the most widely used training helicopters in the world. In 1986, Schweizer acquired all rights to the helicopter from McDonnell Douglas, who had purchased Hughes Helicopters in 1984. After Schweizer acquired the FAA Type Certificate, the helicopter was known for a short time as the Schweizer-Hughes 300C and then simply, the Schweizer 300C. The basic design remained unchanged over the years. Between Hughes and Schweizer, nearly 3,000 copies of the Model 269/300 have been built and flown over the last 50 years. Schweizer continued to develop the Model 300 by adding a turbine and redesigning the body to create the Schweizer 330, and then further developments led to the development of the Schweizer 333.
