The preliminary investigation into the air india crash that took place last month has now been released. It has been reported that the cause of the accident was the failure of the plane's twin engines. Meanwhile, let's take a detailed look at what happened every second from the time the plane took off to the time it crashed. After getting clearance to take off, the plane took off at 1:38 pm. However, this air india Dreamliner plane flew for just 32 seconds before it crashed. At 1:38 pm, one engine reached a speed of 284 kmph during takeoff. In the next two seconds, the plane took off at a speed of 287 kmph. That is, it started flying off the runway.

In the next three seconds, the plane registered a maximum speed of 334 kmph. Then suddenly both the engines failed..\ Due to which the plane started losing altitude, the RAT (Ram air Turbine) was deployed. These RATs are usually deployed in case of twin-engine failure, loss of power or hydraulics.
Why did it not work?
We can clearly see this in the videos related to the air india accident. However, especially when taking off at low altitudes, there is not enough speed. Then the turbine also does not get the required air. Therefore, experts say that activating the RATs in such times is mostly useless.

Important Time:
11:17- The plane arrived in ahmedabad from Delhi.

11:55 - The flight crew performed routine checks.

12:10 - After technical checks, the plane was ready for takeoff

12:35 - The flight crew reached the boarding gate.

1:18:38pm- The plane took off from Bay 34

1:25:15pm - Taxi clearance (runway approach process) was obtained

1:26:08 PM- The plane started taxiing

1:37:33 PM- Takeoff clearance was given

1:37:37 PM- The plane started taking off

1:38:33 PM- V1 speed (153 Kts IAS) was reached

1:38:35 PM- VR speed (155 Kts) was reached

1:38:39 PM- The plane started flying. The aircraft was fully airborne.

1:38:42 PM- The aircraft reached a maximum speed of 180 Kts IAS.

Immediately the Engine 1 & 2 fuel cutoff switches were moved to CUTOFF.

1:38:47 PM- RAT (Ram air Turbine) was deployed; the aircraft began to roll

1:38:52 PM- Engine 1 fuel cutoff was moved back to RUN

1:38:54 PM- The APU inlet door, which allows the aircraft to fly during an emergency, began to open.

1:38:56 PM - Engine 2 fuel cutoff was moved back to RUN.

1:39:05- Fidel called MAYDAY as the aircraft's condition deteriorated.

1:39:11 PM The aircraft crashed. Data logging stopped.

The twin engine started up again within a few seconds after it failed. The fuel cut-off returned to the RUN position again, which shows the same. However, it is clear that the plane could not be saved as it started losing altitude rapidly even before that. The pilots made a MAYDAY call at 1:39 pm. However, the pilot did not get any response as the plane was outside the airport boundary at that time.
