## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) THE PILOT SAID THAT DURING THE RUN-UP, THE MAGNETO CHECKS PRODUCED A ROUGH RUNNING ENGINE. THE PILOT ATTEMPTED TO CORRECT THE ROUGHNESS BY LEANING THE MIXTURE. THE HELICOPTER THEN BEGAN SHAKING FROM SIDE TO SIDE, INDICATING GROUND RESONANCE. DUE TO THE LOW ROTOR RPM, THE PILOT ELECTED TO CLOSE THE THROTTLE RATHER THAN LIFT THE HELICOPTER FROM THE GROUND. THE GROUND RESONANCE INCREASED AND THE PILOT COULD NOT CONTROL THE AIRCRAFT.
