## Narrative

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

(-23) ATTEMPTING TO TAKE-OFF FROM RUNWAY 29 THE PILOT RE-ROTATED THE MAIN ROTOR AND ADVANCED POWER. DURING THE TAKE-OFF ROLL THE PILOT CHECKED THE MAIN ROTOR RPM AND NOTED 160RPM. AT THIS POINT HE WAS TRAVELING APPROXIMATELY 30MPH. AS HE APPROACHED TAKE-OFF SPEED OF 50MPH HE AGAIN CHECKED MAIN ROTOR RPM AND THE DISPLAY WAS BLANK. FULL POWER SHOULD NOT BE APPLIED TO THIS AIRCRAFT UNTIL MAIN ROTOR SPEED REACHES 200RPM. THE PILOT ELECTED TO CONTINUE THE TAKE-OFF AND APPLIED FULL POWER. THE MAIN ROTOR BECAME UNSTABLE RESULTING IN SEVERE VIBRATION. WHEN THE PILOT REDUCED POWER THE MAIN ROTOR STRUCK THE GROUND CAUSING THE AIRCRAFT TO EXIT THE LEFT SIDE OF THE RUNWAY, WHERE THE LEFT LANDING GEAR COLLAPSED AND THE AIRCRAFT CAME TO REST.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
