Air India AI 171 Crash in Ahemdabad (34 Viewers)

Hello everyone! As a fellow traveler myself, over the years I have flown on both Boeing and Airbus aircraft via airlines like Spicejet, IndiGo & Air-India since I was a kid in primary school. On some occasions I have flown on ATR-72 turboprops as well.

I have quite a few photos which were clicked by me at the airports during my trips. I also have a few videos (window-view alongside the wing) of taking off & landing too. Maybe I can post a few screenshots through which we can analyse the motion of the control surfaces (Ailerons, Flaps etc) which can help us fellow DFBians in our own investigation.

About the crash, I have a few theories which come to my mind.
1. This was a classic case of stall because of inadequate lift by the wings due to some discrepancy with the moment of the control surfaces.
2. Both the engines failed. If both the engines indeed failed then a RAT must have been deployed (as pointed out by a few posters through screenshots). The RAT acts as a backup power source when both the aircraft's engines fail or some other hydraulic malfunction. But then again, it's a very interesting case indeed. Statistically we know that traveling by air is the safest compared to land and water. The failure of even one engine in modern aircraft is extremely rare, let alone two engines. If one engine failed, no issues. The aircraft can still fly with one engine and make it back home safely. But two engines failing simultaneously is almost unheard of, I mean when was the last time something like that occurred in the history of aviation? Almost never if remember.

Before every flight, there is always a thorough inspection done of each aircraft to assess whether or not the aircraft is fit to fly or needs some repairs before the next flight. How is it possible that the inspection team didn't notice anything that could indicate a potential failure of both the engines? Were they derelict in their duty or something else was in play here? We don't know.
3. It was due to pilot error. Human errors are one of the leading causes of accidents in aviation.
4. Maybe it was a combination of all the above? Who knows, anything and anything can happen these days.

Whatever may the reasons, I hope the blackbox and flight recorder gets retrieved from the wreckage of the Air India Boeing 787 and a thorough investigation is done into the matter. Us members here can only guess and put forth conjectures from what OSINT we have with us.

R.I.P to the souls of the departed, I can't fathom what those passengers must have gone through during the last moments before the crash.🙏🏻
 
Likely causes..

1.Flaps up before gear up…basically stalling the lift…fully human factor.

2.Both engine fail…impossible to recover.

3.Single engine fail…recoverable.

4.Flight control surface jammed…hard recovery specially at 400 ft.

5.Fuel flow compromised or fuel corrupted.
I also strongly incline towards 4 & 5 .. I fear to even think of option 1 , that would be disaster for AI in the short and long run
 
Remember reading some reports in economictimes and elsewhere that Indian commercial pilots are some of the most overworked in the world. High time DGCA did something about this
DGCA already did it and the new FDTL is coming into effect from July and most airlines are already released new contract based on the new FDTL hours ..
 
RAT is on the right side just behind the wing…

Is this right or left side?
Also RAT can be really Helpful on landing when aircraft not in need of maximum thrust , RAT can provide that little power to glide the aircraft for a safe touchdown compared to aircraft which has lost both engines on take off ..
 
People can speculate all they want, but we will only know for sure when the FDR and CVR is recovered.

Dual engine failure seems unlikely, but electrical failure is a possibility.

Looking at the aoa, they were clearly trying to climb but the lack of thrust stalled them.

If this happened an hour or two at higher flight levels, they could have recovered. At that altitude, there is no recovering from a stall.
 
Btw the 787 has an impeccable track record till now.

Unfortunately things fail and mistakes happen.

I already see some idiots on reddit blaming pilot error, with fuck all information to back that view.
 
How the surviver jumped off the plane ?
He was seated on close the the emergency exit, So my guess on the impact the structure would have broken into 3 pieces and he was lucky to be seated exactly at the place where the front section broke so he would have simply jumped may be from the crashed aircraft into the building . before the fire engulfed the entire plane .. most people would had little chance as they would had very little time to get out of their seats . At take off even the cabin crew who are taught to help passengers on evacuation are seated in their jump seat and in an accident like this they could do nothing and most passengers in panic would have stumbled upon each other and could not exit before the entire aircraft was on fire ..

Explosion in the fuel tanks leading to loss of control systems and power to the engines?

I cannot think of any other reason for an explosion, unless we consider sabotage...
