Saturday, June 4, 2011 10:15 PDT

NTSB Narrative Summary Released at Completion of Accident

According to the pilot, while on a sightseeing flight he flew over a mesa and commenced a hover maneuver about 12 feet above a ridge line. When the wind speed increased he attempted to depart the area. The pilot stated that he encountered a strong downdraft in the estimated 20-knot wind. While flying toward lower elevation terrain on the lee side of the mesa in an effort to depart the area, the helicopter's skids impacted rocks and the helicopter rolled over.

NTSB Probable Cause Narrative

The pilot's failure to maintain adequate clearance from terrain while attempting a transition from hovering flight to forward flight over a mesa in windy, downdraft conditions.
