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 the approach for landing to a wet runway, he experienced a tailwind that pushed the airplane further down the runway than intended as he crossed the threshold. During the landing roll, the pilot applied the brakes but discovered that there was more standing water on the runway than expected, resulting in the airplane hydroplaning. The airplane subsequently overran the end of the runway onto soft ground and through trees resulting in substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
