During the landing roll, the pilot reported that he saw trees ahead and increased brake pressure, but as he did so the nose tilted forward and the airplane nosed over. The vertical stabilizer and left wing sustained substantial damage. The pilot reported there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot of a tail-wheel equipped airplane landing at an unpublished airstrip reported that he made a 3-point touchdown, moved the flight controls full aft, and applied brakes.

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.
