The pilot in the helicopter reported that, during a night solo training flight, the helicopter was on the ground with the throttle rolled on and full collective friction applied when he used a flashlight to view the Hobbs meter. Unbeknownst to him, the collective crept up, the helicopter rolled to the right and dynamically rolled over. The helicopter sustained substantial damage to the horizontal stabilizer, and the main rotor system. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal flight operation.
Probable Cause: The pilot's failure to maintain helicopter control while on the ground when his attention was diverted, which resulted in a dynamic rollover.
