- Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary
- Wire
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
The pilot reported that he wanted to "fly the river" on the return leg of a cross country flight. He further reported that he was going to fly at a lower altitude over the river, but before doing so, he did a low reconnaissance pass to look for people and objects. After he determined that the area was "safe", the pilot entered low altitude flight above the river. Subsequently, the airplane struck a cable that spanned the river cutting the aircraft in half, the aircraft then impacted the river and incurred substantial damage to the fuselage and wings.
The pilot reported that there were no pre impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
Probable cause
The pilot's failure to maintain clearance from a cable while maneuvering at a low altitude over water, which resulted in a collision with a cable and impact with water.

- 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.
