SHORTLY AFTER TAKEOFF, THE HELICOPTER'S ENGINE SUDDENLY INCREASED IN SPEED.  AT THE SAME TIME, THE HELICOPTER IMMEDIATELY YAWED TO THE LEFT, AND LOST POWER AND CONTROL TO BOTH THE MAIN ROTORS AND THE TAIL ROTOR.  THE HELICOPTER DESCENDED RAPIDLY, IMPACTING SLOPED TERRAIN.  AFTER TOUCHDOWN, THE HELICOPTER ROLLED ONTO ITS RIGHT SIDE.
