The Curtiss AT-9 was designed to transition new pilots from single engine trainers to twin engine combat aircraft such as the B-26 and P-38. A relatively difficult plane to fly and especially hard to land the Fledgling served well in the early years of World War II. Nearly eight hundred AT-9s were built for the Army Air Force between 1941 and 1943. After 1943, there were enough B-25 and B-26 bombers available for some of them to be used as trainers and the AT-9 was phased out of service. Very few AT-9s entered the civil market after the war and none were used for long.
