Accident Overview
An airline transport pilot (ATP) was conducting a sightseeing flight over Denver. The pilot had a total of 9 hours in the helicopter model, with 6 hours as pilot-in-command. The flight began with a hovering takeoff to the north, followed by a 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.
Sequence of Events
The pilot landed the helicopter on a taxiway from an altitude of 25 to 30 feet. During the landing, low rotor RPM was noted, which resulted in a hard landing. The impact caused damage to the skids and the lower cabin area of the helicopter.
Post-Accident Inspection
A post-accident inspection was conducted by an Airframe and Powerplant (A&P) mechanic. Although an engine run was not possible, a complete pneumatic, fuel system, and compressor inspection was performed. No evidence of an engine malfunction or failure was noted during the inspection.
