Probable cause
The pilot’s decision to initiate the visual flight into instrument meteorological conditions, which resulted in his spatial disorientation, failure to maintain helicopter control and subsequent impact with water.
NTSB analysis
The commercial, instrument-rated pilot was departing under special visual flight rules clearance in instrument meteorological conditions. Shortly after takeoff the pilot encountered a dense fog bank while flying over the calm water of a river. He stated he attempted to turn around, but he lost his visual reference with the river. The pilot stated he then attempted to climb but became disoriented and a few seconds later the helicopter impacted the water.
Examination of the airframe and engine revealed no evidence of any preaccident mechanical failures or malfunctions that would have precluded normal operation.
