What does a RAT deployment sound like inside the cabin? Could the mere deployment be perceived as the 'loud bang' in a high stress situation?

It would be nice to see a graph of g forces/turbulence. An awkward arm or hand position in combination with sudden turbulence and perhaps worn out switches could hit both of them.

Sleeves or lanyards that got caught while moving around? Perhaps there was an attempt to press a radio button, although it would be a strange time to do that. But perhaps an 'oh crap, I forgot to get that frequency ready' moment.

Not really. It might also indicate that he saw them move, knew his hands were somewhere else, or a plethora of other reasons. Even if one accidentally moves a lever or pushes the wrong button, the first response would likely be denial as well, then followed by an 'oh oops, turns out I did'.

The exact quote was

"The aircraft achieved the maximum recorded airspeed of 180 Knots IAS at about 08:08:42 UTC and immediately thereafter, the Engine 1 and Engine 2 fuel cutoff switches transitioned from RUN to CUTOFF position one after another with a time gap of 01 sec."

Does anyone know what the sampling frequency of the data is? If we get one readout per second, then it's possible that a one second difference could only be a millisecond difference in real life, which doesn't necessarily rule out an accidental bump.
If there truly was a second of difference, there aren't many other options than an intentional act. Not necessarily with the purpose of crashing the plane though (confusion, hallucination, distraction, ..)

Again, you can not conclude that from the report.

Different inputs are sampled at different rates. Some very basic info here: https://scaledanalytics.com/2023/04/...uses-767-data/

It's highly likely switch positions are only sampled at 1Hz, and not at 100 Hz. For engine parameters you'll likely want a higher sample rate, as the whole engine could go from perfectly fine to exploded in less than a second.

If you had something like:

08:08:42.96 UTC: cut off switch 1
08:08:43.01 UTC: cut off switch 2

It would likely be recorded as:

08:08:42 UTC: cut off switch 1
08:08:43 UTC: cut off switch 2

Leading you to believe there was one second between these 2 actions, whereas it was actually only 50ms.
