NTSB narrative
AFTER A LOSS OF POWER AND A PROPELLER OVERSPEED, A FORCED LANDING WAS MADE. THE PILOT DIVERTED FROM TWO CHOSEN LANDING SITES DUE TO POWER LINES CROSSING THEM. A ROAD WAS CHOSEN AND DURING LANDING ROLLOUT THE AIRCRAFT'S WING TIP CLIPPED THE TOP OF A FENCE. THE NUMBER 5 ROD BOLT WAS FOUND TO HAVE FAILED.

- 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.
