Leaving aside the oxymoron inherent in that statement, the suggestion that

Perhaps they should do a periodic max power takeoff or ground tests to 104% N1 to flush out any bad fan blades.
is simplistic in the extreme, being based on the assumption that if a blade is going to let go it will do so the first time N1 reaches a certain value and not on some subsequent occasion.

It's particularly irrelevant in this case, given that the NTSB is already reporting indications of metal fatigue at the blade root.
