Analysis

The helicopter was tied down overnight on the helideck of an off-shore oil platform. The pilot stated that the helicopter preflight had been completed before sunrise, and the first flight of the day was scheduled 4 hours 30 minutes later. During the walk-around prior to the flight, the pilot overlooked the right rear tie-down, which was one of four connected to the fuselage. The pilot attempted to takeoff with the tie-down still attached to the helicopter, which resulted in a dynamic rollover. The helicopter remained on the helideck. The helicopter sustained substantial damage to the tailboom and the right side of the helicopter.
