How bout this...After the Bang, all engine parameters went to Zero, except EGT and, the thrust lever jammed at climb power setting.
Bingo
If the EGT was seen to rise it kind of suggests that the engine remained on the wing long enough to display.
Now the investigators should be looking for bits and pieces of anything left behind on the aircraft for their clues even without yet recovering the engine.
I would imagine that the investigation has learned lots more by now on the hows and whys.
I'll be looking for any photos that might show somthing interesting if they turn up on the net
