NTSB narrative
The airplane sustained substantial damage when it struck power lines while maneuvering at low altitude. The pilot-rated passenger reported that the pilot was performing low altitude maneuvers over a river when it struck power lines. The passenger stated that the pilot didn't feel that they had struck the line until she pointed it out to the pilot. They continued the flight and attempted to enter the pattern at two other airports but, because of air traffic in the area, they continued the flight to a third airport. Upon landing the passenger and pilot removed the wire from the airplane and inspected a hole in the aircraft wing. The pilot felt the airplane was still airworthy and decided to fly it back to the departure airport. The pilot and passenger returned to the departure airport without incident.
Probable cause
The pilot's failure to maintain clearance from the transmission line and the pilot's continued operation with known deficiencies in equipment. Factors to the accident were the power lines and the low altitude the pilot was flying at.

- 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. 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.
