On May 2, 2000, at 1020 central daylight time, a Kitfox IV, N4956, collided with trees following a loss of control while landing on a private airstrip on Neenah, Wisconsin. The private pilot received a minor injury and the passenger was not injured. The airplane was substantially damaged. The 14 CFR Part 91 personal flight was operating in visual meteorological conditions without a flight plan. The local flight originated at approximately 0930 cdt. The pilot was landing to the east on a 2,000 foot long, 80 foot wide grass field. He stated he "landed short" and added power. He stated, "...we made the runway easily, but bounced once and headed into a tree." The pilot reported the local winds were out of the east at 12 knots. Inspection of the accident site revealed the airplane traveled off the north side of the airstrip where it contacted a tree.
