According to the pilot in the experimental exhibition airplane, he departed a grass airstrip about an hour after a rain shower. After a 15-minute pleasure flight, he landed on the same wet grass airstrip. He reported that the airplane touched down about 700ft past the runway threshold of the 2,000ft runway at 75 knots, with full flaps and the trim was set nose up. He applied the brakes multiple times, but the airplane overran the departure end of the runway. The airplane's ground speed was about 13 knots when the right wing struck a fence. The airplane sustained substantial damage to the right-wing aileron. Per the National Transportation Safety Board, Pilot Aircraft Accident Report, in the Recommendation section, the pilot asserted that the accident could have been prevented if he had taken into consideration, "the reduced traction offered by the wet grass." The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
