Primary finding
Probable cause
The pilot's inadequate compensation for wind conditions during landing, which resulted in a hard landing.
Investigator assessment
Analysis narrative
The pilot stated that he was approaching a landing zone on a flat pinnacle with a tailwind. The helicopter was within 50 feet of the landing area in a slow, stable, shallow approach when it encountered an updraft. When the helicopter flew out of the updraft, it abruptly descended to the ground. The helicopter landed hard, and the impact buckled the tail boom and sheared off the left landing gear skid.
