During the next takeoff roll, the airplane veered to the left when it passed the center crown in the runway. He reported that the main wheel "caught" a deep rut at the runway edge. The airplane went off the runway and the left wing impacted a cornfield, which spun the airplane around. The landing gear, propeller, and empennage sustained substantial damage. The airport used by the pilot was a privately owned, paved airstrip used only by agricultural spray aircraft. ## Factual narrative The pilot reported that he had departed from the private airstrip on two previous agricultural aerial application flights.
