Delam
Flying control delamination.
It's not unusual to find it and you would expect that if you were to find it it would be on a big check. It isn't a sign of lack of maintainance at the facility where it is found, quite the reverse, they are doing their job properly.
Lead times for flying control surfaces is long although you would expect the next aircraft in the maint line to be robbed of the part required in this case to get the other away.
It's not unheard of for a delay in aircraft servicability off check to be blamed on an item like this when in truth many factors could be holding it up.
Don't think there is anything to see here.
