What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) PIC stated that he hover-taxied to the end of the runway and realized he had not turned on his avionics switch (on the overhead panel). He landed on a slight slope, maintained collective pitch, and released the cyclic to turn the switch on. The cyclic tilted and, with collective pitch producing lift sufficient to keep the aircraft light on its skids, initiated a rolling moment. PIC stated that he felt the motion and may have pulled in more collective that exaggerated the dynamic rollover. The main rotor struck the ground, and the tail boom attachment to the fuselage was deformed. The PIC was not injured.
As the FAA filed it
(-23) PIC STATED THAT HE HOVER-TAXIED TO THE END OF THE RUNWAY AND REALIZED HE HAD NOT TURNED ON HIS AVIONICS SWITCH (ON THE OVERHEAD PANEL). HE LANDED ON A SLIGHT SLOPE, MAINTAINED COLLECTIVE PITCH, AND RELEASED THE CYCLIC TO TURN THE SWITCH ON. THE CYCLIC TILTED AND, WITH COLLECTIVE PITCH PRODUCING LIFT SUFFICIENT TO KEEP THE AIRCRAFT LIGHT ON ITS SKIDS, INITIATED A ROLLING MOMENT. PIC STATED THAT HE FELT THE MOTION AND MAY HAVE PULLED IN MORE COLLECTIVE THAT EXAGGERATED THE DYNAMIC ROLLOVER. THE MAIN ROTOR STRUCK THE GROUND, AND THE TAIL BOOM ATTACHMENT TO THE FUSELAGE WAS DEFORMED. THE PIC WAS NOT INJURED.
