The NTSB's narrative final · quoted from the NTSB record

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.
