Read the full NTSB narrative
The pilot reported that shortly after takeoff from a touch-and-go landing, the engine began to lose power and eventually quit. A forced landing was made to a field. During the landing roll, the airplane was substantially damaged. An engine inspection found that the number one intake valve was stuck open. Further inspection found that the number one exhaust cam follower head broke in three pieces. Debris from the exhaust cam follower was found jammed between the cam and the cam follower to the number one intake plunger assembly of that cam follower. A section of the engine casing also broke away from around the number one intake cam follower. Maintenance records indicate that the engine total time was beyond manufacturer's recommendation for time between overhaul.
