I'm not saying that damage won't happen, but will the pilot have to shutdown engines? or is it only a maintenance finding on the ground?
Unlikely the pilot would shutdown to be fair.
That report shows the HPT blade (the blade in the photo has been through a repair cycle already). It would have been interesting to also see a fillet cut on the blade, you will normally see a lot of accumillation in the serpentine passages in the airflow "deadzones". It would have also been nice the see the LPT blade 1, which is a shrouded blade with an interlock.
