On July 29, 2000, at 1615 central daylight time, a Piper PA-22-150 tail-wheel equipped airplane, N3514P, was substantially damaged when it impacted a ditch during landing roll at the Calico Rock-Izard County Airport near Calico Rock, Arkansas. The airplane was registered to private individuals and operated by the pilot. The private pilot, sole occupant of the airplane, was not injured. Visual meteorological conditions prevailed, and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 personal flight. The cross-country flight originated from Oshkosh, Wisconsin, approximately 1000, and was destined for a private airstrip near Greenbriar, Arkansas. The FAA inspector, who responded to the accident site, reported that the airplane touched down about 750 feet from the approach end of the 3,000-foot runway. During the landing roll, the airplane encountered standing water and began to hydroplane. The airplane exited the west side of the runway, crossed over a taxiway, and impacted a ditch. Examination of the airplane, by the FAA inspector, revealed that both main landing gear were collapsed, and the fuselage beneath the pilot and copilot seats was damaged.
