Aircraft Accident/Incident Report

Merced, California 95348
Tuesady, August 5, 2003 13:00 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported he was landing on a concrete pad at a construction site. The helicopter was not positioned completely on the concrete landing pad, and the aft section of the skids were hanging off the pad. While lowering the collective, the helicopter rocked back and the tail rotor skid touched the ground. The pilot abruptly attempted to pull the helicopter back into a hover, and the helicopter moved forward and started to roll to the right. The pilot was unable to stop the rolling movement, and the helicopter struck the ground, coming to rest on its right side.

NTSB Probable Cause Narrative

The pilot's excessive movement of the helicopter's controls during an aborted landing, which resulted in a loss of control (dynamic rollover) and an in-flight collision with terrain.
