According to a source familiar with the matter, Indian investigators will delay the release of their final report on the 'deadly Air India Boeing 787-8 crash until the anniversary of the accident, which is Friday. They are citing the need for a complete analysis of the engines of the aircraft.

The sequence of events on June 12th, 2025 as described by Indian investigators' preliminary report published on July 12, last year.

Air India Dreamliner VTANB landed at Ahmedabad as AI423 at 05:47 GMT.

07:48 GMT - An aircraft was spotted departing Bay 34 of the airport.

The aircraft was cleared to taxi by air traffic control at 07:55:15 GMT. A minute later, the aircraft took the taxiway R4 from the bay and proceeded on the runway 23.

08:02 GMT - The aircraft has been transferred from tower to ground control.

08:07 GMT - Take off clearance issued.

The aircraft began rolling at 08:07 GMT.

Aircraft lifted off at 08:08 GMT. The report stated that "the aircraft air/ground sensor switched to air mode in accordance with liftoff."

Aircraft reached maximum airspeed of 180 knots at 08:08 GMT. "Immediately after, the Engine 1 fuel?cutoff switch and Engine 2 fuel cutoff switch transitioned one by one from RUN position to?CUTOFF with a gap of 1 sec."

The Engine N1 and N2 started to degrade from their takeoff values when the fuel supply was cut off.

In the cockpit recording, one pilot is heard asking another why he cut off.

"The other pilot replied that he didn't do it."

The airport CCTV footage showed Ram Air Turbines (RATs) being deployed immediately after take-off.

The aircraft began to lose height before crossing the perimeter wall of the airport.

The RAT hydraulic pump started supplying power at 08:08 GMT.

Fuel cutoff switch for Engine 1 has been changed from CUTOFF (fuel off) to RUN.

The fuel cutoff switch for Engine 2 has also been changed from CUTOFF (stop) to RUN (run).

When fuel control switches are moved from CUTOFF (cut off) to RUN (run), each engine's full-authority dual engine controls (FADEC), automatically manages the relighting and thrust recovery of ignition and fuel.

Engine 1's core speed deceleration stopped and reversed. It then began to recover. Engine 2 could relight, but it was unable to stop core?speed deceleration. Fuel was added repeatedly to increase core speed acceleration.

The pilot who sent "MAYDAY Mayday Mayday" at 08:09 GMT.
