After performing a couple 360-degrees turns and slow flight, the pilot attempted a power-off stall. To prepare for the power-off stall, the pilot retarded the throttle and applied carburetor heat. During the recovery of the power-off stall, the pilot “rapidly” applied engine power, closed the carburetor heat, and the engine lost power. The pilot attempted to restart the engine, however, the restart was unsuccessful. During the forced landing to a field, the pilot landed the airplane downwind, impacting crops and terrain. Examination revealed a buckled firewall.
