The prototype TT-1 Pinto trainer first flew in 1956 and was proposed as a competitor to the Cessna T-37. Although 14 were built for the USN by Temco Aircraft, by 1960 they were retired. In 1968, American Jet Industries flew an uprated version with a more powerful engine as the T-610 Super Pinto which was to be built in the Philippines, but this failed to materialise

14 Pinto aircraft were delivered to training squadron BTG-1 at Naval Auxiliary Air Station Saufley Field, Florida from July 1958, to test the feasibility of an all-jet training syllabus. Performance was poor and the little jets were phased out in 1960. This airframe presumably survives as the Ezell EJ-1, N4229.

Now displayed at the National Museum of Naval Aviation, Pensacola.
