Analysis

The pilot reported that he lifted off to a 5 ft hover with 4 passengers and 70 gallons of fuel on board. He reported that during the hover check, all instruments were in the green with the turbine outlet temperature at 550 degrees. The pilot stated that he started to move forward and climb into the wind when the rotor RPM began dropping. At that time, he estimated that his altitude was about 10 ft AGL and his ground speed was about 3 to 4 knots. He stated that the aircraft was descending and still moving forward as the pitch was increased to cushion the ground contact. During touchdown, the main rotor struck the tail boom. The density altitude was about 9800 ft.
