On landing roll out the airplane bounced slightly, the pilot stated that he inadvertently applied excessive brake pressure and the airplane nosed over, sustaining substantial damage to the rudder, vertical stabilizer and left lift strut. The pilot stated that there were no preaccident mechanical anomalies with the airplane that would have precluded normal operation. In the recommendation section of the NTSB Accident/Incident Reporting Form 6120.1, the pilot stated that the accident may have been avoided if he had executed a go-around, used less aggressive braking, ensured the control yoke was full aft and used a short burst of power to keep the tail down, or landed at a different location. ## Factual narrative The pilot was landing his tundra tire, tailwheel-equipped airplane at an off-airport site.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
