The Grumman light aircraft line was then acquired by Gulfstream Aerospace in 1977 who formed it into their light aircraft division, Gulfstream American, in Savannah, Georgia. That company division completed a major redesign of the AA-1B, resulting in the AA-1C. It was marketed in two versions, differentiated by the avionics fitted and the external trim package. The Lynx was targeted at private owners while the T-Cat was the flying school trainer. These names were chosen to position the aircraft in the Gulfstream American line which, at that time featured the Cheetah, Tiger and the Cougar.
