NTSB Narrative Summary Released at Completion of Accident
The pilot reported that during the landing roll, at approximately 35 to 40 mph, the aircraft developed a substantial shake. The tail then lifted and the aircraft nosed over and came to rest inverted. After the aircraft was righted and during the tow to the hangar, the brakes were tested and found to function with no evidence of a mechanical failure or malfunction. The pilot later reported that he did not apply the brakes nor did the tires slide.
NTSB Probable Cause Narrative
Nose over during the landing roll for undetermined reasons.
