Does it sound like one of em Shaheed drones?

Ram air turbine deployed? Dual engine failure?

Highly likely pilot error. The inexperienced co pilot was supposed to retract the gear but he instead retracted the flaps . If you see the cockpit layout of the 787, the flap lever is nearer to the copilot seat while the gear lever is on the captain side.

But yea, investigators have the FDR so very soon we will know...flap settings, engine performance...etc...

deswai i prefer his version because it based on final report + his opinion instead of speculative noise right now.

But final report will take a long time. 😁

And I watch many many episodes of air crash investigations, mentour, green dot to learn a bit...so I'm dying to know what went wrong like many...

But yea some peeps like they already know fo sure what happened lar like flaps not down when video tak nampak apa pun... 😆

Unofficial / unverified...

Some sources saying last msg to ATC was a mayday call by Captain Sumeet Sabharwal.

If comms with ATC was being conducted by Captain Sumeet Sabharwal, then he was the pilot monitoring?
Isn't the pilot monitoring the one responsible for retracting the gear?

Once positive climb is attained, pilot monitoring would verbalize it, pilot flying would confirm and call for gear up.
Pilot monitoring would then carry out the gear retraction.

Seems unlikely for an experienced line training captain to make a noob mistake like retracting the flaps instead of the gear?

If  the ATC communication is true, then it means the aircraft lost all engine power/thrust at about 600 feet after takeoff. The BIG question still is, why the landing gear was still not retracted at that point.?
....... Note that, AFAIK, the landing gear is normally retracted very soon after lift off from the runway (after the takeoff run), ie once positive (rate of) climb has been achieved, ie at around 100 feet, and not at above 600 feet.
.
*
I read the plane was only about 400+- feet in the air. The airport is about 200+- feet above sea level.

Anyway.

If. If, ada dual engine problem and the plane did not achieve or sustain a postive rate of climb.
Could it be the reason?


Also, the plane crashed 32s after takeoff.

I think the pilots were focused on the engines?
If engine tak hidup, raise gear also, plane will glide another X meters and still crash?



Ok, admittedly.

If he had glided double the distance, he could have reached the SabarMati River,
saved everyone and become India's Sully?

Sully's case is small plane + coming in for landing so less fuel = less weight

AI171 is 787 with full load of fuel tank.... they will need to dump fuel before even attempting an emergency landing if they can control the plane
*
Sully landed in the Hudson River with enough fuel for a flight from NY to Charlotte and Seattle shortly after takeoff.

He was flying an A320. Smaller perhaps than a 787 but its no Cessna 😁

another good analysis


@6:50 the landing gear position is something very few people talked about

Interesting.

Can confirm the fwd tilting of the gear occurs on a real plane as it does on a flight simulator game 😆

4. both engine failure - his speculation on the reason why the aircraft went down, based on the movement of aircraft and other points above. On reason on why both engine flamed out, he said his hunch was fuel quality based on his previous experience being based in bharat.
I don't know. Why only this particular plane? Many other planes were refueled and flying without incident.


I wonder if the maintenance people made a mistake / did something to the plane in Ahmedabad after it flew in from Delhi.





I think we've all seen Akash's video where he complains about AC etc not working.
The 787 flew in from Delhi to Ahmedabad as AI-423 a couple of hours earlier
and was then scheduled as AI-171 from Ahmedabad to London.

One of the memory items for dual engine failure on 787...

Fuel Control Switches: Cutoff then Run




Plane crashed in 32 secs, who TF knows what they managed to do in that time without the report, CVR, FDR...





Smells like some quarters are trying to push the narrative and blame the the pilot(s).
Perhaps some giant of the industry will not survive another MAX debacle.

I hope the prelim report is released soon.

It's interesting to see where the pilots hands are during a typical 787-8 flight when the fuel cutoff switches were alleged to have been moved in the Air India flight.



Perhaps, it is around 01:13 in the video.





In the video, it is the female Captain that is pilot flying but in the Air India flight, many are saying that it was the First Officer in the right seat that was the pilot flying.

Yes indeed, they take turns to fly.

Anyway, I finally found it in the prelim report. 😁

First Officer as pilot flying 787








Captain retains control of the throttle in case of takeoff rejection.

I think the Captain has ample opportunity to alter the fuel cutoff switch if it has to be either of the pilots.

Ranganathan also raised questions about mental health oversight in Indian aviation, citing reports from serving Air India pilots that one of the cockpit crew had a known medical condition and had been on extended medical leave prior to the crash.
