The plt entered the Detroit city arpt area from the west with winds from 280 degrees at 18K gusting to 23K. At 150-175 ft AGL the plt added power in order to reduce his closure rate, traveling southeasterly at the time. The acft then started yawing to the right. The plt was unable to stop the yaw with left pedal displacement. He stated that the rotor RPM decayed with full throttle. The collective was lowered & at 5 ft the plt attempted to level the acft, however the acft landed tail low.
