A helicopter rolled over after the pilot lost directional control during a pedal turn in a hover, landing hard on the left skid.

Incident Overview

A helicopter pilot was approaching a helipad for landing on a heading of 160 degrees. The aircraft was brought to a stationary hover at approximately 5 feet above ground level. The wind was reported as 140 degrees at 10 knots.

Maneuver and Loss of Control

The pilot initiated a pedal turn to the right, intending to change the heading to 250 degrees. During the turn, the pilot found that applying full left pedal was insufficient to stop the rotation. Attempts to fly the helicopter out of the turn by directing it into the wind were unsuccessful.

Landing and Rollover

The pilot then reduced power and attempted to land while the helicopter continued rotating to the right. The helicopter touched down hard on the left skid, subsequently rolling over. The event ended with the helicopter on its side.
