## Probable cause

The pilot’s failure to attain a proper touchdown point during landing with a tailwind which resulted in a runway over run. Contributing to the accident was a wet runway.

## 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.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
