There has not been such a bulletin.

The reason why the report does not mention which of the pilots ask " why did you cutoff ? " is unknown. We also do not know why it was written the switches ' transitioned' instead of ' moved' .
My guess it was either for political reasons or because of a possible criminal investigation.

For a pilot there is no reason to set both switches to cutoff without any reason. There was no engine fire. There was no discussion in the cockpit about using the switches.
Nothing. A mistake is extremely unlikely. There is no reason why the hands of a pilot needs to be near the switches. I do not believe in a brain fart.
That almost started so well!

But the report doesn't suggest one of the pilots moved the switches - it avoids that question entirely. Instead, as you correctly state, it says the switches 'transitioned', which is the strangest way to describe a pilot physically switching them off. I could see that as merely cautious phrasing, but it then describes them as 'transitioning' on again.

Admittedly, I'm a bit rusty with this kind of work these days, but I believe (and so does a former colleague) that the reason these actions are described in this way is that there is no evidence discernible (in time for the report) to identify how those switches were moved. Or even - just to be pedantic since they began in RUN and were discovered in RUN amongst the wreckage - that they moved at all.

I'm not drawing any conclusions, just saying that in the absence of any evidence they could report, they didn't report on any evidence, and 'transition' is the choice how to do that.

I seriously doubt the report fails to identify which pilot asks 'why' and which says 'I didn't' for political reasons. There is too wide a constituency of members of the team and no purpose to be gained, but there would be a possibility it isn't mentioned due to potential legal/criminal investigation if it weren't for the fact that it clearly doesn't actually have that effect at all, and isn't in the AAIB-India remit anyway. If they have no evidence of mental health conditions for either pilot, it's a moot question at this stage in any event.

The only way you can read the report as an investigator is that they itemise all the material facts they know, and omit what isn't yet pertinent or known.

Lets focus on the omit of the report the name of the pilot who said " why did you cutoff" and the name of the other pilot.
Fact is there is a recording on the conversation recorded and available to the AAIB. There are multiple microphones in the cockpit. One for the cockpit, and one for each of the mic of the headset.
Even when the mics of the headsets were not working as a result of power failure, pure on the difference in voices the AAIB knows who said what.

So it was a choice not to write in the report what was known.

That is not correct. Normal procedure, as mentioned in various posts in this thread, is to only include facts without analysis. Determining which person said something on a compressed recording, likely containing various types of noise, will definitely require some analysis. Your statement is pure speculation and likely wrong. The CAM is per definition recording a lot of things and does not come with a neat automatically generated script with attributions.
A preliminary report can only contain what is certain. The attribution you want is unlikely to be available yet.

Apologies for the delay in responding to your point, but as I explained previously, the preliminary report was almost certainly written to place on record everything pertinent that is known. If something wasn't included in it, then it either isn't known, or more likely at this stage, was not considered to be pertinent.

Given that we do not know what evidence there is, even as there is certain to be more to gather, some of us can happily speculate, though not with any authority. But this would basically tell us that if the investigators know who said what, that at this stage, in the context of what THEY know rather than we do, it wasn't pertinent to report that detail.

And really, in preliminary report terms, where the objective at this stage is to lay out WHAT happened, the question of who said what, when it would seem to be a single question and a single answer, isn't relevant in laying down the pertinent facts. That is unless (and until) there is reason to suspect a deliberate or actionable act by a member of the crew. There appears not to be any evidence of mental or physical health impairments which would lead that way at present and point towards the WHY, so no purpose in diverting their and our attention as yet from the WHAT.

I say this as someone who has done this kind of investigatory work, and authored reports from it, knowing that there is sometimes considerable tension between the need to investigate and be thorough and precise, and the public interest which reasonably demands and should have answers.

I have not posted on here in many years, but I feel compelled to do so now. I am a current 787 pilot and I have previously flown most Boeing types and an Airbus too. I also have an extensive background and qualifications in human factors, training and assessment. Before anybody reads any further, perhaps acquaint yourself with the notion of Occam's razor. That is, the simplest explanation is the most likely explanation. I was certain that after the preliminary report was released the preposterous conspiracy theories would finally cease, but no! It's 2025 and humans can no longer help themselves. In my opinion the captain committed suicide here. Simple.

To those suggesting an electrical phantom turned the fuel control switches off without them moving: no. Ask yourselves this: what made one pilot (PF and F/O in my opinion) ask the other "why did you cut off?" Firstly, some context. The 787 fuel control switches make a VERY distinct metallic *CLICK* sound as they are operated. EVERY 787 pilot knows it and won't forget it. It is audible even at high thrust settings owing to the 787's exceptionally quiet engines and cockpit. After rotation the pilot flying is fixated on the HUD; rotating towards the TOGA reference line (~12 degrees pitch attitude) and putting the flight path vector over the flight guidance cue. One hand would be on the control column and the other on the thrust levers. Alternatively he could have had both hands on the control column. In either scenario, the pilot flying's (again, my opinion the F/O's) inboard arm would block his peripheral view (he's focused on the HUD, remember) of the center pedestal and the fuel control switches. HE WOULD NOT SEE THE PM TURN THE FUEL CONTROL SWITCHES OFF. Ipso facto. We know the F/O was PF from the report. If the F/O stopped flying the aircraft and reached down to move the FCS from cutoff to run the captain would've plainly seen the whole thing. I can't imagine "why did you cutoff?" would be his words of choice! More like "WTF ARE YOU DOING?!?" More to the point, if the PF (F/O) did stop flying and reach down to cut one engine off, the captain would have had time to either stop him flicking the second FCS off or at least quickly flick them both back to run and potentially save the day. This plainly did not happen. So it was almost certainly the PM (Capt) that moved the fuel control switches.

So what would make the PF ask the PM "why did you cut off?" if he couldn't see it happen? You would never assume with a loss of thrust that the switches had been turned off. Never. It's not a procedure. It's not a thing. Bird strike? Sure. Fuel Contam? Maybe. But the point is, in the heat of battle at 150 odd feet, you'd never jump to the conclusion that the fuel control switches were off. Never. So what triggered the PF asking the PM why he cutoff? Because he HEARD the fuel control switches move from run to cutoff, that is why. He heard those distinctive *CLICK* sounds (and yes, you can easily flick them both in less than a second FWIW) followed by the engines immediately rolling back. He would then have looked down at the switches and noticed they were in cutoff. The point to be made here is that the switches were moved by the captain. They made their distinct sound. There were no phantoms. They cannot move on their own. They didn't simultaneously fail. This drew the PF's attention away from flying and triggered the question "why did you cutoff"?

Inadvertent selection of the wrong switches? No. The PM was a training captain with thousands of hours experience on the jet. I asked one of our most experienced examiners how many times he'd seen that done. The answer was "zero". Even the stab switches next to them. They're red, guarded and are of a completely different shape and operation. Gear or flap? Come on. I think we're starting to stretch things a bit now. EVEN IF it was inadvertent switching. The INSTANT you'd made that error, you'd go "oh whoops", and flick them back to run. I know startle... I teach it. This is different. You don't flick the fuel control switches off, hear the engines roll back and sit there wondering what happened for 10 seconds AFTER THE F/O JUST ASKED YOU IF YOU CUTOFF! You did something that had an instant effect on the flight. The report indicates that "why did you cutoff" was asked just after both engines rolled back. But it took another 10 seconds to flick the FCS' back to run. If it was inadvertent, the instant the other pilot called out your error you'd correct it. The report makes it clear that there was 10 seconds between that happening. 10 seconds is a LIFETIME in that situation. The training captain knew what he was doing. He only switched the FCS' back to run once he knew it was moot.

So, why did he respond that he didn't move the switches? As per other input from people on here, when people are suicidal they often want to throw authorities off their trail. Or maybe he wanted to confuse the F/O so he didn't flick them back to run himself, or to just buy himself more time while the F/O tried to wrap his head around things? Maybe he didn't want the F/O to die knowing it was a suicide mission. Maybe we'll find out more in the final report or police investigation if things proceed that way. Maybe we'll never know.

I acknowledge that this is my opinion and of course there could be things we don't yet know about, but I must say I'm surprised that some of the theories on this professional pilot forum are no more coherent or logical than those being sprouted on social media.

That is a compelling observation that is hard to avoid the uncomfortable facts. The audio tape for the couple of seconds after takeoff will be getting a close scrutiny.

Thank you for "telling it like it is"! Just to clarify one point for doubters--the "click" or "clunk" that the FCS makes--is it due to the internal toggle mechanism or due to the locking detent clicking back in after you let go of it? If you smoothly pull the lever up, switch from RUN to CUTOFF (or vice versa) while holding the spring part of the lever up and then very slowly and gently release it so that it settles in quietly, will it still make the noise? I'm assuming it will because large, heavy duty 4-pole toggle switches typically have a pretty good snap to them, both in feel and sound--but I haven't heard one of these specific switches.

This is likely to be very close to the final report. The switches moved themselves and all the other nonsensical scenarios being brought up make zero sense and in most cases simply could not happen.
As to not putting out the CVR there is always tremendous outside pressure on an investigation of this scale. Air India is important to the nation. As someone else mentioned when the final report is published it will be old news. Time works for Air India in this case. They appear to finally be making solid progress on a return to financial solvency. The powers to be are not going to jeopardize that turnaround. The answers will come with the final report at a time when it will do far less damage to Air India.

im not saying it\x92s correct but it does only fuel the simmering Indian (domestic) audience\x92s views of a US/Boeing \x91coverup\x92

what new details were actually revealed here, it didn\x92t counter the facts laid out by the AAIB prelim at all so it\x92s not like we can claim the AAIB is covering up and the US has to issue counter factuals (as with the China Eastern 737)
I can fully understand and appreciate the leaking. I have been studying the bull!!!! reporting by India media about the cause of this crash. Former senior pilots, some who flew the B787, tell complete utter nonsense about possible technical issues. Like the engines failed and that was the reason to set both switches to cutoff.

It is important to know who asked ' why did you cutoff'. Because it confirms that captain, who had both hands free, set both switches to CUTOFF for no reason.

has the Indian media cited the AAIB as a reference? A lot of people have spouted nonsense on this subject regardless of nationality- the most popular aviation influencers/commentators have changed their stories about 3-4 times already and amplified outright Misinformation

im not sure how that justifies those with privileged information clearly on the US side leaking undermining the official investigation that is being run with international observers from multiple countries and in line with ICAO guidance

I\x92m not saying it is but it gives off more fuel to idea that Boeing has deep sway inside the US elites and institutions

your last paragraph is conjecture, we can speculate but the job of the investigators is to be 100% accurate, it\x92s easy for us to sit on the sidelines and throw out whatever theories we like but their responsibility is much higher

if US entities aren\x92t happy with the tone/substance of the preliminary report their is a mechanism for them to provide there own findings at a later date, this cloak and dagger selective leaking stuff really is uncalled for

Great post. Agree with your reasoning here. I also don't post often, and after this, I think I will return to the quiet life when surfing online forums.

Because he HEARD the fuel control switches move from run to cutoff, that is why. He heard those distinctive *CLICK* sounds (and yes, you can easily flick them both in less than a second FWIW) followed by the engines immediately rolling back. He would then have looked down at the switches and noticed they were in cutoff. The point to be made here is that the switches were moved by the captain. They made their distinct sound. There were no phantoms. They cannot move on their own. They didn't simultaneously fail. This drew the PF's attention away from flying and triggered the question "why did you cutoff"?

Inadvertent selection of the wrong switches? No. The PM was a training captain with thousands of hours experience on the jet. I asked one of our most experienced examiners how many times he'd seen that done. The answer was "zero". Even the stab switches next to them. They're red, guarded and are of a completely different shape and operation. Gear or flap? Come on. I think we're starting to stretch things a bit now. EVEN IF it was inadvertent switching. The INSTANT you'd made that error, you'd go "oh whoops", and flick them back to run. I know startle... I teach it. This is different. You don't flick the fuel control switches off, hear the engines roll back and sit there wondering what happened for 10 seconds AFTER THE F/O JUST ASKED YOU IF YOU CUTOFF! You did something that had an instant effect on the flight. The report indicates that "why did you cutoff" was asked just after both engines rolled back. But it took another 10 seconds to flick the FCS' back to run. If it was inadvertent, the instant the other pilot called out your error you'd correct it. The report makes it clear that there was 10 seconds between that happening. 10 seconds is a LIFETIME in that situation. The training captain knew what he was doing. He only switched the FCS' back to run once he knew it was moot.

So, why did he respond that he didn't move the switches? As per other input from people on here, when people are suicidal they often want to throw authorities off their trail. Or maybe he wanted to confuse the F/O so he didn't flick them back to run himself, or to just buy himself more time while the F/O tried to wrap his head around things? Maybe he didn't want the F/O to die knowing it was a suicide mission. Maybe we'll find out more in the final report or police investigation if things proceed that way. Maybe we'll never know.

I acknowledge that this is my opinion and of course there could be things we don't yet know about, but I must say I'm surprised that some of the theories on this professional pilot forum are no more coherent or logical than those being sprouted on social media.
52 pages and finally we get to the money shot.

For those asking why not wait a bit longer before throwing the switches and hard nose down, why bother? Roll them back here, cause a startle that is JUST long enough and then let gravity and the FADEC start a race. No resistance needed.

That is, the simplest explanation is the most likely explanation. I was certain that after the preliminary report was released the preposterous conspiracy theories would finally cease, but no! It's 2025 and humans can no longer help themselves. In my opinion the captain committed suicide here. Simple.

To those suggesting an electrical phantom turned the fuel control switches off without them moving: no. Ask yourselves this: what made one pilot (PF and F/O in my opinion) ask the other "why did you cut off?" Firstly, some context. The 787 fuel control switches make a VERY distinct metallic *CLICK* sound as they are operated. EVERY 787 pilot knows it and won't forget it. It is audible even at high thrust settings owing to the 787's exceptionally quiet engines and cockpit. After rotation the pilot flying is fixated on the HUD; rotating towards the TOGA reference line (~12 degrees pitch attitude) and putting the flight path vector over the flight guidance cue. One hand would be on the control column and the other on the thrust levers. Alternatively he could have had both hands on the control column. In either scenario, the pilot flying's (again, my opinion the F/O's) inboard arm would block his peripheral view (he's focused on the HUD, remember) of the center pedestal and the fuel control switches. HE WOULD NOT SEE THE PM TURN THE FUEL CONTROL SWITCHES OFF. Ipso facto. We know the F/O was PF from the report. If the F/O stopped flying the aircraft and reached down to move the FCS from cutoff to run the captain would've plainly seen the whole thing. I can't imagine "why did you cutoff?" would be his words of choice! More like "WTF ARE YOU DOING?!?" More to the point, if the PF (F/O) did stop flying and reach down to cut one engine off, the captain would have had time to either stop him flicking the second FCS off or at least quickly flick them both back to run and potentially save the day. This plainly did not happen. So it was almost certainly the PM (Capt) that moved the fuel control switches.

So what would make the PF ask the PM "why did you cut off?" if he couldn't see it happen? You would never assume with a loss of thrust that the switches had been turned off. Never. It's not a procedure. It's not a thing. Bird strike? Sure. Fuel Contam? Maybe. But the point is, in the heat of battle at 150 odd feet, you'd never jump to the conclusion that the fuel control switches were off. Never. So what triggered the PF asking the PM why he cutoff?

I got a lot of stick a week or so back for saying that we were \x93dancing round the elephant in the room\x94 The above quote is rational and thoughtful and will, I am sure be acknowledged as the most likely scenario in the months to come. As an aside, on the 146/RJ that I flew, you had to retard the power levers to flight idle before pushing down on a lever to shut the engine down. Seems a better system.
