Aircraft Accident/Incident Report

Chino Hills, California 91709
Wednesday, June 28, 2006 8:00 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot was flying for a local news service when he heard a loud bang, and made an off-airport precautionary landing. After landing, he reduced the throttle setting to ground idle and locked the flight controls. He exited the helicopter and attempted to locate the source of the noise he had heard. The pilot stated that he found nothing wrong and re-entered the helicopter to resume the flight. After he brought the helicopter into a hover and started to transition into forward flight, the helicopter rolled to the left and impacted the ground. An examination of the helicopter systems revealed no preimpact mechanical malfunctions, failures, or damage which would explain the loss of control.

NTSB Probable Cause Narrative

A loss of aircraft control for undetermined reasons.
