Analysis

The pilot reported that he was departing from a gravel township road for an aerial application flight. During takeoff, he lowered the left wing to compensate for a crosswind. The left spray boom hit a buildup of dirt that was concealed by tall grass on the side of the road. This resulted in the airplane veering off the left side of the road and into a ditch which caused substantial damage to the wing and fuselage. The pilot reported that there was no mechanical malfunction or failure of the airplane.
