AT THE BEGINNING OF THE FLIGHT, THE HELICOPTER LIFTED OFF FROM THE PARKING RAMP AND IMMEDIATELY BEGAN SPINNING AS IT ASCENDED TO AN ALTITUDE OF APPROXIMATELY 200 FEET. WITNESSES REPORTED THAT AT THE PEAK OF THE CLIMB, THE RATE OF ROTATION SLOWED AND THE HELICOPTER BEGAN A RAPID DESCENT. PITCH ANGLE DIFFERENCES IN THE MAIN ROTOR BLADES, ALONG WITH A DECREASE IN THE MAIN ROTOR ROTATION, WERE NOTICED. THE HELICOPTER'S PITCH ANGLE (NOSE UP AND NOSE DOWN) WAS ERRATIC. JUST PRIOR TO IMPACT, THE HELICOPTER STABILIZED AND WAS NOT ROTATING WHEN IT IMPACTED ON THE RAMP A FEW HUNDRED YARDS FROM THE TAKEOFF POINT. THE HELICOPTER WAS ENGULFED IN FLAMES UPON IMPACT. SOME OF THE WITNESSES REPORTED THAT THE HELICOPTER WAS SPINNING TO THE LEFT, WHILE OTHERS REPORTED THAT IT WAS SPINNING TO THE RIGHT.
