NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

While performing a westbound pinnacle approach, the pilot encountered settling with power and decided to go around. During the go-around, the low rpm audio sounded. Still settling, the aircraft was below the pinnacle when the pilot initiated a right turn toward lower terrain. Unable to arrest the descent or clear the terrain, the helicopter landed hard. Surface winds at the closest reporting station were reported as being from 210 degrees at 5 knots.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

the pilot's delay in recognizing the settling with power condition while performing a pinnacle approach, thus delaying his attempted go-around.
