The NTSB's narrative final · quoted from the NTSB record
The private pilot removed the fuel selector valve handle assembly and had the placarded backing panel painted. During reinstallation, the pilot improperly placed the handle and pointer 90-degrees counterclockwise from the correct selector valve position. During the accident flight, the handle was placed in the right tank position indication, but the actual valve position was in the fuel shutoff position. The engine was subsequently starved of fuel and quit. The pilot initiated a forced landing onto wooded terrain and was seriously injured. Further exam of the valve revealed that it was improperly inspected by a mechanic, thus eliminating the detent function only. The engine fuel primer was found unlocked. Exam of the engine and airframe did not reveal any other preimpact mechanical discrepancies. The pilot had been denied a medical certificate due to an unexplained history of alcohol abuse. The FAA revoked the pilot's airman certificate for failure to provide blood test results from blood drawn after the accident.
