Analysis of the plane's engines is ongoing. The crash occurred on June 12, 2025, after the aircraft departed Ahmedabad. The sequence of events details engine fuel cutoff and subsequent loss of altitude.Listen to this article in summarized formatReutersInside the cockpit: How Air India's Boeing Dreamliner flight ended in disasterIndian investigators are expected to delay issuing a final report into a deadly Air India ​Boeing 787 crash by the one-year ​anniversary on Friday, citing the need to complete an analysis of the ​plane's engines, according to a source with knowledge of the matter.Here is the sequence of events - by the seconds - on June 12, 2025, as detailed by Indian investigators in their released on July 12 last year:05:47 GMT (11:17 a.m. IST) - ‌Air India Dreamliner ⁠VT-ANB landed ⁠in Ahmedabad from New Delhi as AI423.07:48:38 GMT - The aircraft was observed departing from Bay 34 at the airport.Also Read: Air India's long history as it continues to face fallout from deadly crash07:55:15 GMT - ​The aircraft requested taxi clearance, which was granted by air traffic control; a minute later the aircraft taxied ​from the bay to Runway 23 via Taxiway R4, backtracked and lined up for take-off.08:02:03 GMT - The aircraft was transferred from ground to tower control.08:07:33 GMT - Take-off clearance issued.08:07:37 GMT - The aircraft started ​rolling.08:08:39 GMT - Aircraft lifted off. "The aircraft air/ground sensors transitioned to ⁠air mode, ‌consistent with liftoff," the report said.08:08:42 GMT - Aircraft reached max airspeed of 180 ​knots. "Immediately thereafter, ​the Engine 1 and Engine 2 fuel cutoff switches transitioned from RUN to ⁠CUTOFF position one after another with a time gap of 01 ​sec.""The Engine N1 and N2 began to decrease from their take-off ​values as the fuel supply to the engines was cut off."In the cockpit voice recording, one of the pilots is heard asking the other why did he cutoff."The other pilot responded that he did not do so."The CCTV footage obtained from the airport showed Ram Air Turbine (RAT) getting deployed during the initial climb immediately after lift-off."The aircraft started to lose altitude before crossing the airport ‌perimeter wall."Also Read: Air India crash report delay expected due to unfinished engine analysis, source says08:08:47 GMT - Both engines' values "passed below minimum idle speed", and the RAT hydraulic pump began supplying hydraulic power.08:08:52 GMT - Engine 1 fuel cutoff switch transitioned ​from CUTOFF to ​RUN.08:08:56 GMT - Engine 2 fuel ⁠cutoff switch also transitioned from CUTOFF to RUN."When fuel control switches are moved from CUTOFF to RUN while the aircraft is inflight, each engines full authority dual engine control (FADEC) automatically manages a ​relight and thrust recovery sequence of ignition and fuel introduction.""Engine 1's core deceleration stopped, reversed and started to progress to recovery. Engine 2 was able to relight but could not arrest core speed deceleration and re-introduced fuel repeatedly to increase core speed acceleration and recovery."08:09:05 GMT - One of the pilots transmitted "MAYDAY MAYDAY MAYDAY".08:09:11 GMT - Data recording stopped.08:14:44 GMT - Crash fire tender left the airport premises for rescue and firefighting.Read More News on...moreless
