NTSB narrative
The pilot was maneuvering the helicopter for a landing near his residence and entered a low hover over a lake in dark night conditions about 200 yards from the shore and his residence. The passenger stated that she was not sure why the pilot decided to do that maneuver before landing. While in the low hover over the water, the passenger saw a yellow/orange flash and water splash on the windscreen. The helicopter yawed to the right and went into the water. Postaccident examination of the airframe and engine did not reveal any anomalies that would have precluded normal operation.
Probable cause
The helicopter's sudden yaw and subsequent impact with the water for reasons that could not be determined during postaccident examination of the helicopter and its systems.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2011-11-25.
