NTSB narrative
While en route, the pilot saw birds in his flight path and banked the helicopter to the right to avoid striking one, after which he felt a vibration. The vibration continued, and the pilot performed a precautionary landing to a marshy area, where the helicopter rolled over, resulting in substantial damage to the fuselage. Examination of the helicopter revealed a dent in one of the tail rotor blades; no evidence of any other mechanical anomalies were noted that would have precluded normal operation. The tail rotor came to rest in marsh water and the blade did not display evidence of organic material consistent with a bird strike; however, given that the pilot identified and was maneuvering to avoid birds just before the vibration occurred, it is likely that the tail rotor was damaged during impact with a bird, resulting in the subsequent vibration.
Probable cause
An in-flight collision with a bird, which resulted in damage to a tail rotor blade, a subsequent vibration, and the pilot’s decision to conduct a precautionary landing to unsuitable terrain.

- 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, cause areas. 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.
