@Redfox:
The MUC accident revealed a very specific problem of the RR Tay engine which has ice impact panels rear of the fan. While the original design had a higher number of small panels designed to just exit the engine to the rear after detachment, a later redesign switched to a smaller number of larger panels which blocked the airflow when detaching.
(That they did detach at all had to do with improper bonding of the panels which in turn may have been caused by an impractical layout of the maintenance manual that distributed the required steps of work over several chapters and used lots of cross-references.)
AFAIK the engines used on the 738 don't have ice impact panels at all.
The Tay panels now have "weak spots" that will break if the panels detach and allow the pieces to exit the engines through the air duct. In addition they're glued AND screwed to the casing.
