y used in the original prescribed ITA. A license amendment would also be necessary if the PWV reveals that the licensee never met the AC because the original ITA, as worded in the license, was flawed. Appendix A to DG-1316, Page A-2 Threshold 2: Engineering Changes Will an engineering change be made that materially alters the determination that the acceptance criteria are met? License amendments would also be necessary if the engineering change results in the need to identify new AC or if the engineering change results in a design for which the AC as written cannot be demonstrated using the original ITAs. Threshold 3: Population of Systems, Structures, and Components Will there be additional items that need to be verified through the ITAAC? A license amendment would be needed if there are additional items subject to verification through the existing ITAAC, but the licensee proposes not to perform the ITAs specified in the ITAAC. An amendment would also be required if new or amended ITAAC are needed to cover new items (e.g., the new items are of a different type than those covered in the original ITAAC). Threshold 4: Complete and Valid ITAAC Representation Will any other licensee activities materially alter the ITAAC determination basis? A license amendment would be needed if an update of the determination basis necessitates a change to any portion of ITAAC in the license for reasons not covered under thresholds 1, 2, and 3.
