NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot refueled his helicopter and was performing a takeoff from an area near the airport’s fuel pumps. As the helicopter began to lift, the pilot allowed the helicopter’s tail to remain in a low attitude. As a result, the aft end of the left skid contacted the ground and the helicopter experienced a dynamic rollover. The helicopter came to rest on its left side, resulting in substantial damage to the fuselage and tail boom. The pilot reported that there were no pre-impact mechanical malfunctions or failures that would have precluded normal operation.

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

The pilot’s improper takeoff procedure, which resulted in a dynamic rollover when the left skid contacted the ground.
