Aircraft Accident/Incident Report
Newark, Illinois 60551
Sunday, April 20, 2008 12:20 CDT
NTSB Narrative Summary Released at Completion of Accident
The pilot reported that during cruise flight he heard a bang and then the engine began to run rough. He immediately diverted to a nearby airport and entered the traffic pattern for a precautionary landing. As the airplane turned onto final approach, he saw an ultralight taxiing on the far-end of the runway that would interfere with his landing roll. He decided to perform a go-around and increased engine power. On the second approach, as the airplane was turning onto final approach, the pilot intentionally shut-down the engine by switching off the ignition and fuel selector. The airplane's main landing gear impacted a barbed-wire fence that bordered the approach end of the runway. The right wing leading edge received substantial impact damage. The propeller and engine support structure were damaged, and the main landing gear had collapsed. During a post-accident inspection, compression was noted on cylinder numbers 1, 2, and 3 when the engine crankshaft was rotated. No compression was noted on the number 4 cylinder. The number 4 exhaust valve was fractured and missing approximately 180-degrees of its valve head. The engine had a total time of 1,996.1 hours and had accumulated 537.1 hours since its last overhaul.
NTSB Probable Cause Narrative
The partial loss of engine power due to the fracture of the number 4 exhaust valve, and the pilot's decision to shut-down the engine without sufficient altitude to ensure a safe glide path to the runway. Contributing to the accident was the barbed wire fence located at the end of the runway.
