Analysis

An ATP plt was conducting a sight seeing flt over Denver. The plt had 9 hours total time in this model helicopter, 6 hours as PIC. A hovering takeoff was initiated to the north with left turn to the west after takeoff. Current winds were reported from 220 degrees at 17 knots, gusting to 27 knots. The density altitude was 7,600 feet. The plt landed on the taxiway from 25 to 30 feet altitude, with low rotor RPM which resulted in a hard landing and damage to the skids and the lower cabin area. A post accident inspection was conducted by an a & p mechanic. No engine run was possible but a complete pneumatic, fuel system and compressor inspection was performed and no evidence of an engine malfunction/failure was noted.
