This is very nasty
The fact that the fan blade actualy made it all the way through the fan case must be causing a few sleepless nights at CFM! As you know part of the certification process is a test to ensure that the fan case contains the blade if it comes off.
Judas: Doing the inspection won’t be that bad, PAYING for the damage will be another matter!!!
I have seen pictures of a RR trent that had a blade come off during the take off roll. Now that WAS messy!!
BTW Rolls Royce wrap some of their fan cases in a Kevlar blanket to stop a blade if it gets through.
