Narrative:A ROBINSON R-22 COLLIDED WITH TREES IN MOUNTAINOUS TERRAIN AFTER SUSTAINING LOSS OF ENGINE AND MAIN ROTOR RPM WHILE IN FORWARD FLIGHT AT 20 TO 30 KNOTS 100 TO 150 FEET ABOVE THE GROUND. THE MAIN ROTOR RPM DROOPED ABOUT 3 TO 4 PERCENT TO 101 PERCENT. THE PILOT FAILED TO IMMEDIATELY LOWER THE COLLECTIVE TO REGAIN LOST ROTOR RPM AS SPECIFIED IN THE FLIGHT MANUAL.
