I was thinking the same thing - the CF6-50 is becoming somewhat notorious for loosing turbine discs.
I've been at a couple CF6 operator conferences where GE hammered on the need to do the inspections, etc. to prevent turbine disc failures. The problem is the operators that are bursting turbine discs are not the ones that bother to go to operator conferences (or apparently pay much attention to the associated ADs
).
