Analysis

The pilot was on a local flight when he noticed a thunderstorm approaching. He headed back to the airport where it was raining and the visibility had lowered. According to the pilot, he landed on runway 15, but when he applied brakes the aircraft began hydroplaning and he was unable to stop. The aircraft collided with a ravine 400 feet beyond the runway end.
