They never say every message. It would appear from their initial report that fuel starvation has been ruled out, as there was no mention of lack of fire, low fuel warnings, etc…. so thats one answer. The cutoff is the most likely cause, but having so many flights in the left seat reaching around to grab the flaps, i just cant see it. But its all impossible until it isnt. The big problem i have is both engines being starved of fuel(for whatever reason) at the same time. Both cutoff is consistent with this. I guess we will find out in a year and a half when the docket is published.
