Analysis

Plt had landed on prepared area (snow packed down by heli ski guide) to embark ski passengers. On departure plt lifted to hover, turned to desired hdg and initiated forward transition. As acft passed boundry of packed snow, rotor wash picked up soft loose snow, obscuring visual references. Acft had not achieved translational lift and engine was at max torque output, negating climb. Plt attempted to 'set acft down' but run-on landing resulted. Due to excess forward speed and soft snow, acft nosed over.
