Structurally Significant Item

All structural items are then either classified as Structurally Significant Items (SSIs) or other structure. An item is classified as an SSI depending on consideration of consequences of failure and likelihood of failures as well as material, protection and probable exposure to corrosive environments. All SSIs are then listed and categorized as damage tolerant or safe life items to which life limits are assigned. (reference)
