Probable cause
The pilot’s selection of unsuitable terrain for the landing, which resulted in a nose over when the airplane encountered soft sand during the landing roll.
NTSB analysis
The private pilot reported that he was landing on a sand bar near a river, where he had previously landed several times before. During the landing roll after traveling about 100 ft, the airplane encountered soft sand, nosed over, and came to rest inverted. The airplane sustained substantial damage to both wings and the empennage. The pilot reported there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
