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 during takeoff from a remote beach site, soft sand pulled the airplane to the left, so she aborted the takeoff and repositioned for a second attempt. During the second takeoff attempt, just prior to rotation, the airplane’s right wheel contacted the water, which pivoted the airplane to the right, and it nosed down into the shallow water. The right wing sustained substantial damage. The pilot reported that there were no pre-accident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
