Accident
The pilot reported having no braking effectiveness after landing to the west on a wet 1,000-foot-long grass runway. He stated that he misjudged the distance needed to stop, causing the airplane to go off the runway into a corn field.
Weather and Wind
Weather reported at an airport approximately 19 nautical miles away indicated winds from 060 degrees at 4 knots. The pilot, however, reported that the wind was calm at the time of the accident.
Performance Data
Interpolation of performance data from the Pilot's Operating Handbook (POH) showed that with flaps extended to 40 degrees, power off, and maximum braking applied on a dry grass runway, the airplane's ground roll would be approximately 1,068 feet in calm wind. With a 4-knot tailwind, the ground roll would be approximately 1,260 feet.
Pilot Statement
When asked how the accident could have been prevented, the pilot said, "Could have powered up and went around." He also reported that there were no mechanical deficiencies with the airplane.
