At about 1010 Mountain time, the airplanes pilot executed a forced landing following a loss of engine power. The solo student pilot was not injured; the airplane sustained substantial damage to its left wing. Visual conditions prevailed. After a seventh touch-and-go, and on the upwind leg after reaching 400-500 feet agl, the engine quit. The student attempted to restart the engine but was unsuccessful. During the forced landing onto a dirt field the outboard section of the left wing was damaged.
