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 😆

I was in a meeting with Natarajan Chandrasekaran in Bombay House when this happened and he had to leave to meet with government in Delhi... What a mess that day was...

now everyone starting to pay attention to the RAT

hopefully the preliminary report comes out soon so the poor pilots name can be cleared

This is what the taiwanese pilot speculated as well, in one of his analysis, just a few hours after the crash. He is an active pilot of b787. Someone shared his video in the RWI tered.

Among his analysis, as per my understanding

1. no flap deployed - he said this is not possible due to the b787 system and warning tone will be incessant if this happen. he mentioned most casual bird enthusiasts will mistaken b787 flap settings coz it features newer wing design and some airlines encourage its pilots to use minimal flap setting for take-offs due to eco concern. And this will appear as no flap to casual watchers/followers.

2. RAT - He said he notice what appeared to be ram air turbine in the crash video, and as an active pilot, he said he know there was an severe emergency n board. Most likely both engine flameout coz both RAT was deployed and aircraft lost altitude. He mentioned b787 sys tem will deploy RAT automatically when it sensed twin engine failure.

3. LG not retracted - he said SOP for b787 is to retract the LG when aircraft has +ve climb and below 200m. In the event of both engine failure he said pilots can'r retract the LG coz there was no power, unless they manage to 1. restart the engine 2. switch on the APU. Both of which pilots had not enough time to do in that short 30s timeframe

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.

The RAT on the all-electric B787 is auto-deployed when .......

1. both engines failure, or
2. total electrical failure, or
3. total hydraulic failure.

If both engines failed just after liftoff at about 100-200 feet (= RAT auto-deployed) before the landing gears could be retracted, how come the ill-fated B787 could still climb to about 600 feet before losing altitude and crashing to the ground.?

So, I'm leaning towards "2. total electrical failure" just after liftoff, ie not "1. both engines failure", = the B787 had full power/thrust but could not climb above 600 feet because the LG were still extended, maximum weight load and hot afternoon summer temperature of 38*C (or plus got sudden tailwind or windshear).

Its high tech plane. Its extremely rare for both engines to stop especially IF proper maintenance performed(which is compulsory after each landing). They will take fuel sample to check etc. And AI said total electrical failure is extremely unlikely for modern plane like this.

But its too miracle for that kind of immediate explosion can have survival without any major burn somemore.

Fyi, .......

- Etihad 787-10 Heathrow Push, Start, Taxi, Takeoff, Climb to FL370 - 11 July 2024
= "Positive Climb", "Gear Up" at 7:38 video mark is normally very soon after liftoff, likely at about 50-100 feet = landing gear retracting.

Why was the ill-fated B787's LG still not retracted at 600 feet.?

India will send the black box of the crashed Air India Boeing 787 aircraft to the US for analysis. The recorder sustained heavy external damage from post-crash fire making it impossible to extract data in India, people aware of the development said.
