NTSB narrative
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.
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.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, cause areas. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
