NTSB narrative
Witnesses observed the weight-shift-control aircraft flying at a low altitude down the river, and the solo student pilot waving to people on the ground. As the airplane approached a set of transmission wires about 100 feet above the ground, the pilot banked the airplane sharply right to avoid them. One witness said the bank angle was more than 90 degrees. It is likely that the pilot was unable to maintain control of the airplane during this maneuver as it lost altitude. The airplane subsequently struck another set of wires about 30 feet above the ground and cartwheeled to the ground.
Probable cause
The student pilot’s abrupt maneuver to avoid transmission wires, which resulted in his loss of airplane control. Contributing to the accident were the pilot’s decision to perform a low-altitude flight, his distracted attention, and his failure to monitor the environment for objects.

- 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.
