Air Tractor Inc AT-802 N22FK accident near Benson, Minnesota

Probable cause

The pilot’s failure to adequately survey a field for obstructions prior to a low-level aerial application pass, which resulted in an impact with a powerline. Contributing to the accident was the degraded visibility due to the smoke in the area.

NTSB analysis

The pilot reported that on the afternoon of the aerial application flight, the visibility was degrading due to smoke from nearby wildfires. Upon arrival at the target field, he circled twice to study the powerlines and obstacles, where he observed two distantly spaced power poles, and mistakenly thought they were termination points of a powerline. During the low-level aerial application pass, the airplane subsequently impacted a powerline as he flew between the power poles. The pilot returned to the airport and landed without incident. The airplane sustained substantial damage to the right aileron. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
