Accident Sequence
A private pilot was diverting to another airport because thundershowers were present at the intended destination. While on short final approach, the pilot reported heavy rain conditions. After touchdown, the pilot stated that forward visibility was zero and that the airplane was hydroplaning. Crosswind conditions were also reported at the time of the accident. The pilot was unable to stop the airplane within the remaining runway length, and the airplane subsequently collided with a ditch.
Witness Observations
Three witnesses at the airport reported that the pilot landed halfway or further down the 4,000-foot long runway at a faster-than-normal speed. Their observations corroborate the pilot's account of the landing conditions and the inability to stop before reaching the end of the runway.
Environmental Conditions
The accident occurred during a period of heavy rain and crosswind. The pilot specifically noted zero forward visibility after landing and hydroplaning, which likely affected braking effectiveness. The runway was 4,000 feet long, but the pilot landed beyond the halfway point, reducing the available distance to stop.
