Analysis

After completing a normal run-up & mag check, the plt hovered in ground effect. A normal takeoff was then made in groundeffect. At about 200 ft AGL the plt noticed the RPM dropping from 2900 to about 2700. He tried to restore by dropping collective & increasing throttle, but there was no response & the RPM continued to drop. He then restored collective to 33-34 inches of mp but RPM still continued to drop. At about 300 ft AGL & with the RPM last observed at 2300, a forced landing was made on a 45 deg sloping dirt pile.
