The Grumman American AA-1 series is a family of light, two-seat aircraft. The family includes the original American Aviation AA-1 Yankee and AA-1A Trainer, the Grumman American AA-1B Trainer and TR-2, plus the Gulfstream American AA-1C Lynx and T-Cat.

James R. Bede was an American aircraft designer and developer, particularly noted for his development of influential, fast, efficient, light aircraft, including his BD-1, and the BD-4, BD-5 and BD-10 kitplanes. He designed well over a dozen aircraft starting in the 1960s, but a string of business failures, and legal, technical and safety problems kept most of these designs out of widespread use.
