A rodent chewing on wires. Vibration-induced chafing. Tin whiskers causing an intermittent short. There are many possibilities, those came to mind first.
But why does the pilot then comment that they are in the CUTTOF position and move it to RUN? A mechanical failure would have to also move the physical switch in the cockpit for the audio recording to make sence.
You have the exact CVR audio? The report says "one of the pilots is heard asking the other why did he cutoff" which I interpreted to mean one of them noticed the engines shutting down, and asked the other if he did that.
It amazes me that some people can ever make it out the door if they spend all their lives contemplating a series of increasingly unlikely possibilities.
We know that the switches physically moved from the run to the cutoff position because one of the pilots noted that they were in the wrong position. We know that they were moved back to the run position because they found in that position. I don't understand how a short could explain that - it really seems like someone would have had to physically move the switches.
What we have is reported speech: "In the cockpit voice recording, one of the pilots is heard asking the other why did he cutoff. The other pilot responded that he did not do so."
So we don't know the exact words used. Did he say for example, "Why did you move the switches to cutoff" or did he ask "Why did you cut off the engines"? If there are indeed two shorts (astronomically low as those probabilities are), the other pilot would say "I didn't", look around confused and then (possibly?) flip both of them down and back up? Which could explain the 4s delay in pulling them back up.
Speculation, but since we do not have actual transcripts or recordings, all I'm doing is answering speculation with more speculation.
Do we know that the pilot noticed they were in the wrong physical position, or did some other status indicate the engie fuel had been cut?
I would be surprised if there was only one channel for this information
