Swearingen SX-300
The Swearingen SX-300 is a high-performance homebuilt aircraft, featuring two seats and developed by Ed Swearingen of San Antonio, Texas during the 1980s. The aircraft was offered as a kit, but the kit was not a comprehensive kit like contemporary designs and its construction was beyond the abilities of the average amateur aircraft builder. The plane features a six-cylinder engine. Plans have been made to revive the plane and offer it as a quick-build kit, but there is no current kit being offered.
There are eight known crashes of SX-300 aircraft, ten deaths.
