Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot had made 3 landings at unimproved landing sites on the morning prior to the accident with no issues. Subsequently, while landing on a gravel beach and after the main landing gear touched down with the tail wheel still elevated above the terrain, both main landing gear sank into a soft spot in the gravel; the airplane stopped and nosed over. The substantial damage to the airplane included the engine mount, front wing struts, the top of the rudder, and wing ribs being bent. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
