    This has arisen before and the answer is yes you can do UT and Eddy Current through TSA. I have executed it many times so is a practical answer. Now there can be issues. A major operator reported issues and we found that the TSA spec plays a part. If no sealer coat is applied the surface can be very rough and abrasive and causes excessive probe wear and coupling issues. The HOIS collaborative poked at this some 10 years ago.
