Analysis
The aircraft nosed over in a ditch during a landing on a gravel road after an aerial application flight. The pilot said that he lost directional control during landing rollout and one main gear went into a ditch. The aircraft then nosed over and came to rest inverted. The pilot reported the winds were shifting direction and changing velocity all day.
