Some random thoughts on this AD
It seems to be a data gathering and not a conclusion.
7500 hours does not relate to a confirmed safety of flight situation.
But it is movement in a direction to at least gather pro or con information about a possible problem in a timely manner.
It reminds me of the initial response to the fuse pin issue with the B747 between CI and El Al accidents.
So I will await the inspection results (data vs postulations)
