On May 22, 2000, at 0700 mountain daylight time (mdt), a Cessna T188C, N2075J, owned by Aerial Crop Care Incorporated was substantially damaged during an aerial application flight 12 miles south of Elgin, North Dakota. Visual meteorological conditions prevailed at the time of the accident. The 14 CFR Part 137 flight was not operating under a flight plan. The commercial pilot reported no injuries. The flight originated from Hebron Municipal Airport, near Hebron, North Dakota, at 0600 mdt. The pilot told a Federal Aviation Administration inspector that during a swath run the right main landing gear impacted the terrain. He said he was able to maintain control of the airplane and returned to the point of origin where he landed the airplane without the benefit of the right main landing gear. He said the damage was caused during the initial impact with the terrain and not the subsequent landing at Hebron. In a report the pilot stated: "After having made several passes, I turned around and entered the field again on a slight down hill, I did not notice a 'nob' in the field and hit it with the right wheel. I looked out the right window and saw that the boom was gone."
