Aircraft involved
Probable cause & findings
The pilot’s abrupt maneuver to avoid hay bales during the takeoff roll, which resulted in a loss of directional control.
Factual narrative
The pilot of the tailwheel-equipped airplane reported that, during an aerial application flight, approximately 800 ft. into the takeoff roll on a gravel airstrip, he veered the airplane to the right to avoid hay bales that were stacked on the left side of the runway. He added that as the airplane veered right, the right-wing spray boom encountered tall wheat, and the airplane exited the right side of the runway. Subsequently, the airplane came to rest nose down. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
