USA
Established 1982 by Ed Swearingen.
Manufactured aircraft components and offered aircraft modifications, plus developed and marketed as SX300 a two-seat kitplane (marketed by Airight Inc). Also produced SA-32T Turbo Trainer prototype for Jaffe Aircraft (first flown 1989), and developed SJ30 entry level business jet (first flown 1991).
This is now Sino-Swearingen, due to an influx of Taiwanese money, thanks to the efforts of Lockheed, which needed offsets for their sale of F-16s to Taiwan.
