Aircraft Accident/Incident Report
Southern Timbalier 52Ca, -- 00000
Monday, March 12, 2012 10:00 CST
NTSB Narrative Summary Released at Completion of Accident
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.
NTSB Probable Cause Narrative
The pilot’s inadequate preflight inspection when he did not remove a tie-down strap prior to takeoff, which resulted in a dynamic rollover.
