What happened
At 10:50 am, the pilot departed from a grass airstrip in an unidentified aircraft carrying 50 gallons of water mixed with dye. The objective of the flight was to perform a swath width and uniformity test by spraying the dye over a string positioned east and west at the west end of the runway.
The pilot initiated the swath run at an altitude of approximately 10 feet above the ground, starting roughly one-half mile north of the target string. As the aircraft approached within 300 feet of the string, the pilot observed orange cone markers intended to indicate the flight path over the center of the string.
While attempting to align the aircraft with these markers, the pilot lowered a wing into the grain. This contact caused the aircraft to drag sideways across the surface. Upon impacting the ground in this attitude, the landing gear was torn from the aircraft.
