Analysis

The helicopter was flying 200-300 AGL over 8,000 ft terrain elevation at 80 knots. The plt reported encountering wind gusts slowing his ground speed to zero. The acft then started a rapid vertical descent while still indicating 80 k. the plt attempted to arrest the descent but the right skid collapsed on impact & the acft rolled right shearing the m/r blades & twisting off the tail boom.
