Established in 1970 by Dott Ing Stelio Frati, designer of a series of light aircraft from the Ambrosini F.4 to F.250 (subsequently developed as the SIAI SF.260), to develop aircraft of Frati design mostly for manufacture by other concerns. First was the F.20 Pegaso light twin; two prototypes built (first flown 1971) and an agreement was reached for production aircraft to be manufactured by Italair. Also designed the Canguro transport (developed by SIAI-Marchetti but became a VulcanAir type) and the Jet Squalus (see Promavia and Alberta Aerospace). Produces F.22 Pinguino two-seat aerobatic lightplane and trainer in several versions with retractable or fixed undercarriages (first flown June 1989), the F.22 Bupp variant with only fixed undercarriage and other changes, plus the F.220 Airone four-seat development.

General Aircraft Corp / GAC

Long Island, New York, USA
The company was established at Lowell, Massachusetts to build an aircraft designed by Doctor Otto C. Koppen, a professor of aeronautics from the Massachusetts Institute of Technology. The aircraft was the G1-80 Skyfarer, a two-seat cabin high-wing braced monoplane.

Before the company could produce the aircraft in any numbers the Second World War intervened, and the Skyfarer programme was abandoned after 17 examples had been built. Situated on Long Island, New York, the company became a manufacturer of the Waco CG-4A troop glider and the interests in the Wayfarer were sold to Grand Rapids Industries in 1943.

In 1969, the company bought the Helio Aircraft Company which specialised in building STOL aircraft for use by government agencies in south east Asia. The company ceased to manufacture aircraft in October 1976 when it sold the production rights and assets of its Helio Aircraft division.
