Probable cause

The pilot's inadequate preflight inspection in failing to ensure that all skid tiedowns were removed prior to the attempted takeoff.

Analysis

The helicopter was operated from a helipad on the fishing vessel m/v kali for fish spotting missions. The ship was in the territorial waters near Pago Pago, American samoa and the time listed above for the accident is local ship time. During the attempted takeoff the helicopter rolled over on its left side; however, it remained on the ship during the entire sequence. Ship crewmen who witnessed the accident reported that the left rear skid was still tied down to the helipad platform when the helicopter attempted to takeoff. The ship sustained damage to the deck and bulwark plates.
