After touchdown, the airplane continued beyond the end of the runway and nosed over, coming to rest inverted. As a result of the accident sequence, the airplane sustained damage to the rudder and vertical stabilizer. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. He opined that the accident may have been prevented if he had maintained a slower approach speed and touched down at the runway threshold. ## Factual narrative The pilot stated that he was landing at a remote grass airstrip.

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.
