According to the pilot, he satisfactorily completed a pre-takeoff check, which included checking the exhaust gas temperature gage for correct temperatures. He then departed into the wind. The pilot reported that about 50 feet AGL, and airspeed about 30 to 40 mph, he noticed the main rotor slowing down and he added power with no results. He entered autorotation, but the rotor speed was inadequate to perform a successful autorotation, and the helicopter touched down hard. An engine examination revealed a half inch crack within a welded seam in the mid section of the exhaust manifold. The pilot reported that the exhaust manifold was delivered from the factory with the weld. The helicopter had a total of 56 hours since new.
Probable Cause: A leak on the exhaust manifold which resulted in a loss of engine power.
