(SB-09-56) NTSB Determines Uncontrolled, Progressive Flooding Caused Sinking Of Alaska Ranger

Washington, DC – The National Transportation Safety Board determined today that the probable cause of the sinking of the Alaska Ranger was uncontrolled, progressive flooding due to a lack of internal watertight integrity and to a breach of the hull’s watertight envelope, likely caused by the physical loss of a rudder. Contributing to the loss of life was the vessel’s movement astern, which likely accelerated the flooding and caused the liferafts to swing out of reach of many crewmembers.
