1 person had minor injuries.

The pilot's failure to maintain aircraft control resulting in an uncontrolled descent and subsequent roll over. Low altitude flight and the pilot's encounter with settling with power were contributing factors.

Read the full NTSB narrative

The flight instructor reported that they were in the process of practicing "maximum performance takeoff abort - backwards." The student was on the controls during the maximum performance takeoff phase to an altitude of about 150 feet above ground level, and the instructor took over the controls to demonstrate the abort procedures. The instructor took the controls just prior to call for the abort. When the abort phase began, the instructor applied aft cyclic and slightly lowered the collective. The helicopter had been in a tail low attitude and started to descend into "settling with power." The instructor applied forward cyclic and lowered the collective, however the helicopter did not have sufficient altitude to level out or gain airspeed to recover before impacting the ground on the right side skid. The helicopter pivoted around about 180 degrees then rolled over onto its left side.
