NTSB narrative
The pilot reported that, during an agricultural application flight, he started his spray pass from the north and traveled south and added that the sun was bright. During the pass, he avoided numerous obstacles, before he passed over a patch of woods. There was an east-west running powerline located about 100 yards out in the field that the pilot did not see until it was too late to avoid it. The airplane impacted the top of the wires and a pole and a part of a pole embedded itself into the left wing. The pilot was able to land the airplane without further incident. 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.
Probable cause
The pilot did not maintain clearance from a powerline during an aerial application flight.

Source notes (4)
- 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.
