On May 14, 2000, at 1200 central daylight time (cdt), a Beech A23-19, N5665S, collided with the terrain and a swimming pool, following a loss of directional control while landing on runway 36 (3,200' x 60', asphalt) at the Holland Airpark, Holmen, Wisconsin. The private pilot was not injured and the passenger suffered serious injuries. The 14 CFR Part 91 flight was operating in visual meteorological conditions without a flight plan. The flight originated from Reedsburg, Wisconsin, at 1100 cdt. The pilot reported he made a landing attempt with a crosswind from the west-northwest. He reported he "Didn't like [the] attempt" and he elected to perform a go-around. The pilot reported that a gust of wind from the west-northwest was encountered after touching down on the second landing. He reported he was approximately half way down the runway when this occurred. The pilot reported the gust lifted the airplane and moved it to the right of the runway. He reported he "Could not get plane back to runway and ended up in an above ground swimming pool." The accident site was examined by an inspector from the Federal Aviation Administration Milwaukee Flight Standards District Office. The inspector reported the airplane traveled off the right side of the runway where it contacted a runway light, a wind sock, a garden, and shrubs. The right wing of the airplane then contacted a maple tree which yawed the airplane to the right prior to it coming to rest in the swimming pool. The inspector reported the residence where the swimming pool was located was approximately 150 to 200 feet from the runway. Wind reported at LaCrosse, Wisconsin, 11 miles south of the accident site, at 1150 cdt, were from 300 degrees at 15 knots.
