Primary finding
Probable cause
The student pilot’s loss of directional control during a hover, which resulted in an impact with terrain.
Investigator assessment
Analysis narrative
The flight instructor reported that the student pilot was on going on a solo flight after being endorsed and completing a dual instruction flight. As the helicopter lifted into a hover, the instructor saw the student jerk the collective and the helicopter spun to the right. The student attempted to recover with cyclic control inputs, but the helicopter dynamically rolled over and impacted terrain. Subsequently, the fuselage and drivetrain sustained substantial damage. The student pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
