Aircraft Accident/Incident Report
Litchfield, Illinois 62056
Tuesady, July 21, 1998 15:00 CDT
NTSB Narrative Summary Released at Completion of Accident
The pilot reported that the engine began to vibrate and run very rough at an altitude of 4500' MSL. He noticed an immediate loss of power and was unable to maintain altitude. The pilot then cycled the magnetos, increased the mixture control to full rich, confirmed that the fuel selector was in the 'ON' position and applied carburetor heat, all of which had no effect. Being uncertain as to the cause of the power loss and concerned that the engine would quit operating, the pilot declared a mayday and requested vectors. At the time the pilot made visual contact with the airport, the aircraft was at an altitude of 1100' MSL. The pilot chose to land on runway 09 even though there would be a quartering tailwind present upon landing. During the landing rollout, the pilot felt the tail swing to the left at which time the airplane departed the runway toward right, into the grass and impacted a concrete culvert, separated the right main wheel and slid to a stop. The pilot stated that landing was made with full flaps. Examination of the engine revealed that the number three cylinder had a compression of 35/80 and the number four exhaust valve was stuck in the full open position.
NTSB Probable Cause Narrative
Loss of engine power due to an open exhaust valve and low cylinder compression. A related factor was the tailwind.
