The student pilot and flight instructor were performing maneuvers when the engine started to lose power. The flight instructor took control of the airplane and made a forced landing in an open field with uneven terrain. During ground roll, the airplane encountered rising terrain and the nose landing gear collapsed rearward. Examination of the airplane engine revealed that the number two exhaust valve was stuck. The head was missing from the valve stem, and multiple impact marks were found on the top of the piston. Portions of the valve head were recovered in the exhaust and intake manifolds. The cylinder had been replaced 172 hours prior to the accident. The numbers 1, 3, and 4 cylinders had been replaced 51 hours prior to the accident.

Was the failure of an exhaust valve. A factor in the accident was the unsuitable landing area encountered by the pilot.
