FAA Report
Pilot - Flight Instructor; Commercial; Helicopter
The helicopter was following participants in a downhill skateboard race in mountainous terrain. The pilot had just performed a left-pedal
turn and the helicopter was facing upslope to the mountain. The low rotor warning sounded and the pilot lowered the collective and
increased throttle. The pilot stated that the engine did not respond so he continued to lower the collective and looked for a place to
land. During the forced landing on the downsloping terrain the helicopter came to rest on its nose, resulting in substantial damage to
the main rotor, skid tubes, and tail boom. Post accident examination of the helicopter, engine, and systems, revealed no anomalies. The
density altitude was calculated to be 10,600 feet. The pilot calculated the in-ground-effect hover to be 8,500 feet pressure altitude,
the out-of-ground-effect hover to be 5,000 feet pressure altitude, and estimated the gross weight to be 2,320 pounds.
