Aircraft involved
Probable cause & findings
The pilot's decision to land on a rough surface with hidden obstructions (holes).
Factual narrative
The pilot reported that after touchdown on the grass/sod airstrip, the landing roll was normal for about 100 feet, but then the airplane came to an abrupt stop, like it had hit something. The airplane nosed over substantially damaging the rudder and wings. The pilot and ranch personnel inspected the landing area and followed the airplane's tracks back toward the point of touchdown. They found a large hole, likely dug by an animal, approximately 24" deep, and in line with the airplane's right tire track. The pilot said he did not see the hole when flying downwind, nor on the base leg, or final approach. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
