As the U.S. Air Force replaced the last of their T-34As at the beginning of the 1960s, their role taken over by the propeller-driven T-41 Mescalero and the T-37 Tweet primary jet trainer in UPT, those T-34As not allocated to USAF aero clubs or marked for foreign military sales or transfers were turned over to the USAF Auxiliary, the Civil Air Patrol, for use as search aircraft. However, the T-34A's low wing limited its utility in an aerial search and rescue role, and maintenance issues, particularly expensive wing spar repairs that became apparent in the late 1990s, resulted in the last of the former USAF T-34As being withdrawn from CAP service by 2003.
