As I recall, a fuse pin broke, causing a loss of an engine. IIRC, it shot foreward, then struck another engine.
The damage also caused a failure in hydraulic power.
When the plane reduced speed to prepare for landing, aerodynamic forces forced it to roll over.

I know, you said it's not relevent to the discussion. But I figured "what the heck" and descided to tackle it.
