I'm surprised nobody is discussing a possible electrical failure in the context of Boeing's quality problems and whistleblowers and so on. Would that be against the PPRUNE rules? If anyone's interested, here's an article to get you started

Consensus here is, that both engines where stopped by a closing fuel cut off valve, wich yields a fast loss of N2. The generators then shut down very quick as does the thrust in a few seconds. This is supported by the quick RAT extension which allowed the crew to control the flight. The APU did autostart too. A thrust changed with the thrust leaver to idle is much slower and would not result in the dramatic change in performance. Thrust set to idle will not engage the RAT since the electric generators would still work. So a thrust leaver changed to idle or any intervention by Autothrust (AT) would not yield to the RAT extension. Something or someone activated a fuel cut off. How and why that happened is the big question, the investigators have to answer. ![]() Subjects (links are to this post in the relevant subject page so that this post can be seen in context): APU Fuel (All) Fuel Cutoff Fuel Cutoff Switches Generators/Alternators RAT (All) |

The 787 fuel controls do have guards on each side but they're hard to see in the photo I posted. Here's a better angle:

Should FCO require action from both pilots?

I'm sorry to say that OhForSure's suicide theory fits well because:
1) like many suicidal people, the captain may have planned his death in detail. He would have known that cutting the fuel at this altitude would guarantee that the engines could not produce thrust before the aircraft crashed. He would have known that if the other pilot seized control it would be impossible to land in an area empty of buildings. And he would have known that he would be instantly rendered unconscious upon impact, with certain death at the same moment or shortly afterwards. 2) he may have wanted the investigators not to reach a firm conclusion of suicide so that his family would receive an insurance payout, and his family, friends and colleagues would not be vilified or feel guilty about not noticing his mental condition. His mayday call may have been carefully calculated to deepen the mystery of the final moments. He may have chosen fuel starvation at low altitude rather than a vertical dive from cruising altitude because the latter would have looked more like suicide and he'd have had the additional hurdle of preventing the other pilot from saving the day.

Is anyone finding the archived copy impossible to load? I was unable to get at it until I used a VPN to pretend I was in the Netherlands. I could paste the whole thing here if it would help, but it's pretty long. Some people would regard most of it as irrelevant.
