Aircraft Accident/Incident Report
Baker City, Oregon 97814
Thursday, November 8, 2007 12:45 PST
NTSB Narrative Summary Released at Completion of Accident
According to witnesses, after departing the airport, the helicopter turned to the north, climbed to an altitude that was reported to be as low as 100 above ground level (agl) and as high as 800 feet agl. As it approached the accident site location, the helicopter's tail reportedly lowered, it slowed, rotated or turned slightly to the east, and then descended rapidly toward the terrain. Witnesses reported that near the beginning of the descent, the main rotor blades either slowed their rotation significantly or "stopped turning." One witness stated that almost immediately after observing the change in rotation speed of the main rotor blades, "…the helicopter just dropped out of the sky." Examination of the wreckage disclosed evidence of coning of the main rotor blades. No evidence was found of any flight control malfunction or loss of engine power.
NTSB Probable Cause Narrative
The pilot’s failure to maintain main rotor rpm while maneuvering.
