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 reported that before landing at the remote, gravel-covered site, he intended to momentarily touchdown to determine the landing surface suitability, a maneuver commonly known as dragging the landing site. He said that after touchdown the main landing gear wheels encountered an area of rough and water covered-terrain, which slowed the airplane’s ground roll, so he applied takeoff power to go-around. The pilot said that the airplane became airborne, but it remained in ground effect, and he was unable to climb. The airplane subsequently settled back onto the site, and the right main wheel touched down atop a shallow stream that was situated next to the remote site. After touchdown, the airplane veered to the right and nosed over. The right wing sustained substantial damage. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
