NTSB narrative
WITNESSES STATED EVERYTHING SEEMED NORMAL AS THE HELICOPTER CIRCLED OVERHEAD BEFORE BEGINNING THE APPROACH TO LAND IN AN OPEN FIELD AT THE FAIRGROUND. THEY REPORTED THE HELICOPTER DESCENDED TO ABOUT 10 FEET ABOVE THE GROUND, THEN TURNED RIGHT AND STOPPED. THE HELICOPTER DROPPED, TAIL LOW, TO THE GROUND, THEN BOUNCED FORWARD HARD ON THE NOSE SECTION. WITNESSES STATED WHEN THE HELICOPTER BECAME AIRBORNE AGAIN IT WAS SPINNING, AND MOVING TOWARDS THEM. THE HELICOPTER STRUCK ELECTRICAL POWER LINES AND CAME TO REST ON AN ASPHALT ROAD ABOUT 90 FEET FROM THE POINT OF INITIAL IMPACT. POSTACCIDENT INVESTIGATION REVEALED NO EVIDENCE OF PREIMPACT MECHANICAL ANOMALY.

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. 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.
- API snapshot SHA-256: 4549c28619a93b973094b39917796c086263039041e6c24f5b69b995c205fcce; retrieved 2026-09-21T14:17:56.804Z.
