Read the full NTSB narrative

During climbout about 300 feet above the ground, the airplane's engine lost power down to 2000 rpm. The student pilot reported it audibly "lost a cylinder." He stated the EGT showed very hot on the No. 3 cylinder. He stated he verified the mixture was at full rich, and he reduced throttle a little, but the EGT did not improve. He stated he returned to full throttle and almost immediately the "engine stopped hard" within two seconds, and the airframe shook heavily. He glided the airplane toward a road, and the airplane collided with trees and the ground. Examination of the engine revealed compression developed on all four cylinders when the crankshaft was rotated at the propeller flange. Valve train continuity was observed, and both magnetos produced spark on all towers. The air intake box displayed crush damage. The lower engine cowling was removed, and the carburetor was found separated from the intake manifold. The manifold mount studs displayed chafing, one manifold mount stud was bent. One mounting nut and two flat washers were found in the cowling, and the other mounting nuts were not located.
