Analysis
The plt reported that the eng began losing power while he was en route at an alt of aprx 200 ft AGL. He turned & initiated an autorotation to a road construction site. The helicopter landed tail low. Subsequently, the tail boom was chopped off & the helicopter bounced & rotated 180 deg. An exam of the eng revealed the #4 piston had failed. The piston had burnt & molten aluminum had transferred to the stem of the exhaust valve causing it to stick open.
