Aircraft involved
Probable cause & findings
The pilot's failure to maintain directional control during landing. Contributing to the accident was a ditch.
Factual narrative
On August 1, 2007, about 0915 central daylight time, an Air Tractor AT-502B, operated by Keller Flying Service, and piloted by a commercial pilot, sustained substantial damage during an aborted landing on runway 17 (4,018 feet by 75 feet), at the Hampton Municipal Airport (HPT), Hampton, Iowa. The 14 CFR Part 137 aerial application flight was operating in visual meteorological conditions without a flight plan. No injuries were reported. The local flight originated at an unconfirmed time. The pilot stated that while landing on runway 17 at HPT the winds were about 20 knots from the southwest. He said that just as he was touching down the wind speed decreased, which resulted in the airplane yawing to the right. He said that the tires began to skip and he applied power to execute a go-around. He stated that as he crossed the ditch along the right side of the runway the airplane settled to the ground and the left wing tip struck the ditch. The airplane subsequently spun to the left, the right landing gear collapsed, and the airplane slid across the runway. The airplane was substantially damaged when it struck a ditch along the edge of the runway during an aborted landing. The pilot reported that there was a right 45 degree crosswind at 20 knots which decreased just as he was touching down. The airplane then yawed to the right and the pilot applied power to execute an aborted landing. The airplane subsequently became airborne and crossed over the ditch along the right side of the runway. The airplane settled to the ground and the left wing tip struck the ditch edge. The airplane subsequently spun to the left, the right landing gear collapsed, and the airplane slid across the runway. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
