Maybe the xAAs did not ask for cabin crews to become bouncers, but they did ask Boeing and GE to conduct additional inspections / replace parts on this very engine.
This AD was prompted by cracks discovered on one HPCR 8-10 spool between the 9-10 stages in the weld joint. We are issuing this AD to prevent failure of the HPCR 8-10 stage spool, uncontained engine failure, and damage to the airplane.

Never sure what to make of it, but I have heard some rumours about the older GE series before.
