AFTER REFUELING WITH 12.9 GALLONS OF FUEL, THE PILOT TOOK OFF WITH ONE PASSENGER ON BOARD. THE PILOT STATED THAT AFTER LIFTING OFF WITH 104 PER CENT PRM, HE BEGAN A NORMAL SHALLOW TAKEOFF WITH 25 INCHES OF MANIFOLD PRESSURE. HE REPORTED REACHING ABOUT 75 FEET AGL AND 50 KNOTS, WHEN HE NOTICED THE ROTOR AND ENGINE SPEED STARTED DROPPING TO APPROXIMATELY 100 RPM. HE STATED THAT MORE POWER WAS APPLIED BUT THE RPM CONTINUED TO DECREASE. HE STOPPED CLIMBING, LOWERED THE COLLECTIVE, AND BEGAN DESCENDING. SUBSEQUENTLY, THE HELICOPTER TOUCHED DOWN WHILE STILL TRAVELING AT ABOUT 15 KNOTS WITH ABOUT 85 PER CENT RPM.
