For me, the fuselage could not be badly damaged before, otherwise you don't have the leverage, also see engine pylon damage.
I cant help seeing that clean break across the top of rear fuselage former (or construction joint) looks like a fatigue zip failure'
If this had ailowed flex of the whole tail ,what would sudden change in geometry of screw jack and internal struts do to angle of HS?
Overload??
