NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
The pilot reported that he was doing hover testing of his helicopter. He said the tower cleared him to aerial taxi from a hangar on the east side of the field to the compass rose. The pilot said to get to the compass rose, he determined he would have to fly west toward a building on the airport and then turn south to fly behind the building (the west side of the building), and stay between the building and taxiway A, the north-south parallel taxiway to the runway. The pilot said that as he passed behind the building, "I think I experienced a tailwind. The helicopter began losing power and lift. I set up to do a skidding landing. The helicopter skidded and tipped forward, caught the rotor on the ground." The pilot said, "I experienced settling with power and did not have enough altitude to fly out of it." The wind conditions reported 15 minutes after the accident were 360 degrees at 11 knots. An examination of the helicopter revealed no preimpact anomalies.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the pilot encountering settling with power. A factor contributing to the accident was the tailwind.
