On August 1, 1999, at 1500 central daylight time, a North American AT-6G, N98FP, piloted by a commercial pilot, sustained substantial damage during landing, on Runway 33 (4,100 feet by 75 feet, dry/asphalt), at the Harlan Municipal Airport, Harlan, Iowa. The flight was conducted under the provisions of 14 CFR Part 91 and was not on a flight plan. The pilot reported no injuries to himself or to his one passenger. The flight had originated from the Wittman Regional Airport, Oshkosh, Wisconsin, about 1200. In a written statement, the pilot stated that he was landing in a crosswind. The pilot stated that the crosswind correction used on the approach was not "...well stabilized, and [a] go around was contemplated, but [the airplane] touched down and ground looped." The aircraft departed the left side of the runway and struck a small ditch embankment. The aircraft came to rest approximately 100 yards west of the runway. A weather report for a reporting station located at the Aububon County Airport, Audubon, Iowa, which is 20 nautical miles and 70-degrees magnetic from the accident site, was reporting winds from 30-degrees magnetic at 8 knots gusting to 14 knots. A post accident examination of the airplane revealed no preexisting anomalies.
