Aircraft Accident/Incident Report

Poway, California 92064
Saturday, February 25, 2012 14:15 PST

NTSB Narrative Summary Released at Completion of Accident

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.

NTSB Probable Cause Narrative

The pilot's inadequate compensation for wind conditions during landing, which resulted in a hard landing.
