Air India AI 171 Crash in Ahmedabad (8 Viewers)

All valid points as ALPA slams this report. (Especially the media leak without signature/atrribution)

This is looking like a shitshow as the report looks definitely biased (even if it ends up being a pilot error after full investigation)


View: https://x.com/ani/status/1943970848890585265?s=46

FDR data showed fuel supply was cut then restored,. Where is the bias in reporting that? A shitshow would suppress data awkward to some.

Nationalist have gone completely insane over this report both here and online. Embarrassing to say the least.

As if that lone Mirpuri halala product (((brit))) wasn't enough, we have another Boeing simp in here? Barely a few hundred folks visits this thread on a good day, why do these trolls/bots even bother?

Like, both of you can visit plebbit, blame it all on the dead pilots and an entire battalion of incels would agree almost immediately. Why even bother to do all these trollposts here?
 
FAA 2018 advisory was a "potential disengagement of the fuel control switch locking feature" - ie, failure of the safety mechanism.

Not about an airplane moving the fuel control switch, on its own, from "RUN" to "CUT OFF" position like a ghost!
 


Well, their plan doesn't seem to work bcoz most Indians & many abroad too like Mary Schiavo, etc are already rejecting any pilot error, suicide, etc & suspecting S/w glitch or sabotage or maintanance issues.
(Although pilot suicide crash have happened in past, but doesn't look in this case)
At max the planners saved their weekend-off booze parties.:drunk2:
From tomorrow they'll start facing the heat.🔥:shoot:
 
Extremely pathetic state of affairs as the report has been released in the mid of night in India. Who authorized this? Is there any precedent like this before,like any report related to some transport accidents being released in India when almost all of India are sleeping? It just shows the extend of corporate/third party state control/pressure on our institutions. Anyone can make out that this timing is for "sync" in reporting in West.

Makes us look utterly compromised/powerless.

Whatever the report was, it SHOULD have been released during normal working hours.

Expert Claims Pilot May Have Deliberately Crashed Air India Flight​


Captain Mohan Ranganathan, one of India's leading aviation experts, has pointed to the sequence of fuel cutoff switches and cockpit audio to suggest that the crash may have stemmed from deliberate actions.​


View attachment 43078

Again speculations, nothing solid, so far.

View attachment 43079

As per aviation minister the report is only primary & that they are waiting for more concrete data points.

It is just some media like BBC & local charlatans adding exotic wordings to arrive at pre-determined conclusion.

If we see recent videos, podcasts, interviews of Retired Captain Mohan Ranganathan, then he is with 'suicide squad', i mean suspecting suicide.

Although pilot suicides globally have happened, so far with limited data I don't suspect suicide in AI-171, but Cap M.R. has rightly pointed major flaws in our airport infrastructure, ground ops & investigations of past accidents & wrong reports.
Even Gaurav Taneja a.k.a. 'Flying Beast' & actually many other retired people have exposed negligence, mal-practices, over-confidence, pressure work, bad management & even punishment for speaking up, etc.⚠️🚨
 
Aren't both the fuel control switches completely isolated from one another? Both of them failing/glitching in a 1 second window is very improbable.
Yes..its very rare.

I havent even heard of 1 flying thousands of hours on Airbus.
I believe a dual fuel control switch malfunction has never happened yet.

Malfunction can be HARD or SOFT.
Mechanical, Electronics, Electrical guys will know the HARD ones best.
IT guys will know the SOFT ones best.
Moreover, people like Mary Schiavo (former IG, dept of US Transport) & our experts like Dr. Vandana Singh, etc are suspecting SOFT glitch.
Remember what i said since my 1st post about EEC, TAP, TCMA & possible glitch -

It continiously monitors throttle, provides protection against flame-out during ecess rain, hail.
It monitors N1, N2, N3 spool speeds also & if RPM limit crossed then fuel flow would be reduced to lower the RPMs.
The EEC shuts down the engine only if RPM limiting fails & overspeed condition occurs.
If fuel-switch is accidentally shut off then EEC can electronically turn it & ignitors on.
On ground it'll shut down engine if above idle speed and not decelerating normally.
During take-off if 1 engine fails then TAP reduces thrust on surviving engine to safeguard rudder/yaw control.
Last but not least, if the air data sensors are clogged then it can be big problem. Although there are multiple of them for redundancy but accidents due to them have happened.
The ANA 787 incident happened in 2019 & if we deep-dive into the cause then it is complicated.
Boeing clarified that the engines can shutdown as thrust reverser were activated too quickly before ground condition achieved which activated the TCMA or Thrust Control Malfunction Accommodation system which guards against inadvertent asymmetrical high thrust situations. The TCMA would notice high thrust at idle or low speeds on ground w/o decceleration, so engine would be shutdown to reduce speed.
But this is takeoff situation. So i can think of an ECC glitch
- As RAT can auto-deploy when engines below idle RPM, an EEC glitch detecting high EGT for long could reduce thrust by reducing fuel flow. Although such glitch is very difficult to imagine.

MCAS glitch caused 2 crashes of B-737 MAX.
So it is also possible that sensors+EEC glitch can reduce RPM or shut down engines & in the MFD it'll appear like a cutoff operation & the FO being far less experienced than Captain, can misunderstand.


It is possible that certain Captains & FOs don't get along well, but they still have to work together, this happens in every office, human nature. So people who don't get along well in office impulsively/reflexively can misunderstand/suspect each other.

FAA (and Boeing, by proxy) are doubling down on pilot's unintended/intentional error theory.

Considering that lots of other airlines/countries also fly dreamliners this advisory / doubling down is remarkably bold.


"""
The FAA's Continued Airworthiness Notification on July 11 came after a preliminary report on Friday into last month's Boeing 787-8 crash, which killed 260 people, raised questions over engine fuel cutoff switches.

The FAA's notification to Civil Aviation Authorities, seen by Reuters, said: "although the fuel control switch design, including the locking feature, is similar on various Boeing airplane models, the FAA does not consider this issue to be an unsafe condition that would warrant an Airworthiness Directive on any Boeing airplane models, including the Model 787."
"""
 
India better not yield to US now. Use this to beat the hell out of US.

I am pretty sure, no pilot error was made here. The conversation snippet between pilots do not seem to indicate pilot was suicidal.

Only one of two possibilities:
1. Boeing Malfunction
2. or, Maintenance sabotage.
 
A few facts.
1. Switches are mechanical and non motorised. Have to be moved physically.
2. Only one of the pilots was in a position to do it.
3. The safety mechanism stated in 2918 advisory "could" be broken, but at the same time for both switches? Would still need to be physically moved.
4. One pilot asks other "why" he cut off not "if" he cut off. It's irrelevant what the other says.
In india, mental health is a taboo.
I am not a fan of boeing but it would be helpful to everybody involved if we focused on relevant issues.
Instead of bias towards boeing, I think the report is biased towards pilots, in the interest of investigation. I believe there is more in cvr, wouldn't be surprised at a heated conversation or fight.

> A comment on his video reveals that in Embraer jets the fuel cutoff won't be done unless the throttle is pulled back to idle.
"Embraer will not let you shut the fuel off or close the fuel valves unless the throttle aren't at idle. To just kill the fuel with both engines at full TOGO is unbelievable."

1752486217421.webp

This is perhaps a safety feature & in Boeing too, as per 1x engine failure/relight procedure during take-off in B-787 (YT videos) -
- the fuel switch red light turns on.
- Surviving engine is enough for +ve flight.
NOTE - This doesn't auto-start RAT or APU unless additional conditions ar met.
- Both pilots coordinate to follow checklist & acknowledge each other t every step.
- The MFD displays probable reason like fire, etc.
- Auto-throttle switch for affected engine is switched off in UFC panel.
- Affected side throttle is put to idle.
- THEN AFFECTED SIDE FUEL SWITCH IS CUTOFF.

- Fire handle of affected side is pulled up & turned to discharge fire bottle.


View: https://www.youtube.com/watch?v=XZVc3npAltA

This procedure takes time. But in dual failure it is instant emergency. based on this procedure, the pilots should immediately check for fire & if no fire then -
- switch off both auto-throttle switches in UFC panel.
- pull back both throttles to idle.
- switch off both fuel switches then on.
- Either EEC should auto-arm & light the ignitors or engine knobs in overhead panel need to be rotated from NORM to START.

1752491171602.webp
1752491315259.webp

So it is basically a 3-point operation -
- Auto-throttle switch off in front.
- Pull throttles back.
- Switch off fuel switch.

THIS MEANS AS PER S/W CONTROLLED PROTECTION THE FUEL HARD SWITCH CUTOFF OPERATION WILL NOT BE RELAYED FROM FMC TO EEC UNLESS THE THROTTLE IS PULLED BACK TO IDLE.

SO THIS WHOLE ACCUSATION OF CAPTAIN (FAR MORE EXPERIENCED THAN FO) SWITCHING OFF FUEL SWITCHES IN 1 SECOND WHEN THROTTLE IN FORWARD POSITION, IS TECHNICALLY IMPOSSIBLE.



As i said, some people are also suspecting the less experienced FO who might have made some mistake & tried to mislead the CVR.

Preliminary Crash report key points -

> Entire nation waiting for report in working day hours, but Report released in after-work hours IST after midnight.

> Data from forward EAFR downloaded on 24th June 2025.
49 hours of flight data spanning 6 flights including crash flight.

> Rear EAFR significantly damaged. Data couldn't be downloaded by conventional means. >>>>> No info if unconventional means tried or not.

> Earlier an error message 'STAB POS XDCR' or "Stabilizer position transducer" was about the sensor sending data about stabilizer to FMC, which was troubleshooted.

> T/o weight was 213,401 Kgs loaded Vs 218,183 Kgs allowed. >>>>> More weight adds to more loss in altitude. But i guess this is done till allowed limit by all airlines.

> No pilot names or captain/FO mentioned for conversation from CVR. >>>>> WHY????
Only 1 line mentioned about one asking other why he cutoff fuel & other saying he did not. >>>>> Why not full conversation from T/o roll till crash????

> A/c departed from bay-34 at 7:48:38 UTC/GMT, started rolling for t/o at 8:07:37 UTC/GMT, so 19 mins from bay to t/o roll.

> MLG was seen tipped forward (happens when gear lever put up) but gear lever found in down position!!!! >>>>> Perhaps it moved down due to crash impact.

> Thrust levers found at idle but EAFR data says they remained forward till impact. >>>>> Again, perhaps they moved back due to crash impact.

> Fuel switches were found in RUN position (as expected for relight).

> Timeline -
8:8:39 UTC/GMT / 1:38:39 pm IST - take-off, left runway.
8:8:42 UTC/GMT / 1:38:42 pm IST - speed 333 Kph, fuel cut off to both engines in 1 second interval.
8:8:47 UTC/GMT / 1:38:47 pm IST - Both N2 spool RPM went below Idle; RAT hydraulic pump started supporting flight controls.
8:8:52 UTC/GMT / 1:38:52 pm IST - engine 1 switched back on, worked.
8:8:54 UTC/GMT / 1:38:54 pm IST - APU auto start began, inlet door opened.
8:8:56 UTC/GMT / 1:38:56 pm IST - engine 2 switched back on, but didn't work.
8:9:05 UTC/GMT / 1:39:05 pm IST - Mayday call.
8:9:11 UTC/GMT / 1:39:11 pm IST - flight recorder stopped (crash).
8:14:44 UTC/GMT / 1:44:44 pm IST - Airport Fire trucks left airport for crash site.

------------------------------------------------------------------------------------------

Time T = take-off
+3 seconds
T+3 sec = fuel cutoff to both engines.
+5 seconds
T+8 sec = N2 spools RPMs below idle; RAT hydraulic pumps on.
+5 seconds
T+13 sec = engine 1 switched on, worked.
+2 seconds
T+15 sec = auto APU start, inlet door opened.
+2 seconds
T+17 = engine 2 switched on, didn't work.

T+26 sec = Mayday call
+6 seconds
T+32 sec = crash, recorder stopped.

After fuel cutoff -
> RAT deployed immediately & took 5 seconds to start its hydraulic pump (& electricity too).
> APU autostart took 12 seconds to initiate.
> Engine 1 was switched on after 10 seconds.
> Engine 2 was switched on after 14 seconds (4 seconds after engine 1).


> These modern jets are said to survive 1x engine failure continuing +ve flight climb, go around & land.
But,
Heavy A/c contributing to downward inertia post Apogee + RPMs going below idle + only 1 engine relighted giving inadequate thrust for immediate climb, made the plane crash.
So "thrust not achieved" means not enough to go back up immediately.
 
Everything would have been clear if they mentioned if CVR picked up the noise of fuel switch or not.
I remember watching about some other crash where they found out gas(O2?) leak by checking the audio recording, so I am sure toggling of fuel switches must have been audible as well.

May be you missed some critical technical points.
Even if CVR picked the click of switches, it won't work if S/w protection is there, unless auto-throttle disengaged & throttles pulled back to idle.

You expect Captain, far more experienced than FO, to do this kind of procedural mistake or suicide which might have S/w safeguard?

Fair enough but we must keep an open mind . Not everything is a conspiracy and people have tried to ascertain sequence of events based on fact they know .
Pilot error/suicide is the most possible of the outcome but like you said if this is not the case then truth will be out in next 1 year and we will know entire truth .
