NTSB Narrative Summary Released at Completion of Accident

THE ROBINSON R22 BETA WAS ON THE 3RD LEG OF A CROSS COUNTRY FERRY FLIGHT FROM OREGON TO THE EAST COAST. THE MULTI RATED, HIGH TIME PILOT HAD DEPARTED LEWISTON, IDAHO, AND PROCEEDED TO FLY DOWN THE SNAKE RIVER CANYON EN ROUTE TO BOISE, IDAHO. WHILE CRUISING SOUTHBOUND DOWN THE RIVER GORGE, THE HELICOPTER'S TAILROTOR COLLIDED WITH A CABLE SPANNING THE RIVER AT AN ELEVATION OF 50 TO 60 FEET ABOVE THE WATER. THE ROTORCRAFT WAS THEN OBSERVED TO SPIN OUT OF CONTROL, IMPACT THE RIVER AND SINK.

NTSB Probable Cause Narrative

FAILURE OF THE PILOT TO MAINTAIN A PROPER VISUAL LOOKOUT. A FACTOR IN THE ACCIDENT WAS THE PILOT'S POOR JUDGEMENT IN OPERATING AT LOW ALTITUDE ALONG THE RIVER.
