‘Why did you cut off?': Final chat of Air India pilots before Ahmedabad crash revealed in initial probe report
Air India Plane Crash Report: In its preliminary report on the June 12 Air India plane crash in Ahmedabad, the Aircraft Accident Investigation Bureau (AAIB) reveals that the cockpit voice recordings captured the last crucial exchange between the two pilots during the engine failure sequence moments before the deadly accident. The 15-page report reveals that one of the pilots of Air India flight 171 asked his co-pilot, 'Why did you cut off fuel?. The other pilot responded, 'I did not do so.' The exchange took place moments after both engine fuel cutoff switches transitioned from 'Run' to 'Cutoff' at 13:38:42 IST after the Boeing 787-8 Dreamliner reached a maximum speed of 180 knots indicated airspeed. The AAIB report explores the sequence of events and engine behaviour leading up to the incident involving a Boeing 787-8 aircraft and offers the first official insight into what transpired before one of the worst accidents in Indian aviation history. As many as 260 people, including 241 passengers and crew onboard and 19 on the ground, were killed in the accident. One passenger on board the plane survived miraculously. According to the report, both engines shut down mid-air within seconds after takeoff. The fuel cutoff switches moved from RUN to CUTOFF one after another in just one second. "When fuel control switches are moved from CUTOFF to RUN while the aircraft is in flight, each engine's full authority dual engine control (FADEC) automatically manages a relight and thrust recovery sequence of ignition and fuel introduction," it reads. Soon after, one of the pilots transmitted a MAYDAY alert. Air Traffic Control inquired about the call sign but did not receive a response. Minutes later, the aircraft crashed outside the airport boundary into a building. The plane's two pilots were Captain Sumeet Sabharwal, a Line Training Captain with 8,200 hours of flying experience, assisted by First Officer Clive Kundar, who had logged 1,100 flying hours. Why did you cut off fuel? The report said both pilots were medically fit and rested, with adequate experience. It also said that there was no immediate evidence of sabotage, but pointed to a known Federal Aviation Administration (FAA) advisory on a possible fuel switch flaw.

Take-off to cut-off, all safety checks protocol followed: Air India crash probe report
The preliminary report on the Air India plane crash makes one thing clear, all safety measures were adequately taken before and after the take-off, right till the engines cut off. read more This handout taken and posted on the X (formerly Twitter) account of the Central Industrial Security Force (CISF) On June 12, 2025 shows the back of an Air India plane after it crashed in a residential area near the airport in Ahmedabad. Image- AFP As India's Aircraft Accident Investigation Bureau released the preliminary report on the devastating Air India plane crash in Ahmedabad, one of the aspects that remains clear is that adequate safety checks were followed from takeoff to the crash time. The report released on Friday night indicated that fuel to the engine of the aircraft was cut off, leading to the deadly crash last month, which killed 260 people. It is pertinent to note that under international aviation rules, the investigating state must file an initial report with any findings within 30 days of an air crash. STORY CONTINUES BELOW THIS AD The report by the Indian authorities stated that the switches in the cockpit of the Boeing 787-8 Dreamliner moved to a ' cutoff' from the 'Run' position. 'The aircraft achieved the maximum recorded airspeed of 180 knots IAS [indicated airspeed] at about 08:08:42 UTC, and 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 1 second,' the report said. 'The engines N1 and N2 began to decrease from their takeoff values as the fuel supply to the engines was cut off,' it furthered. The aircraft eventually lost altitude before crossing the airport perimeter wall. Apart from this, the report stated that adequate checks were followed before and during the take-off. The checks before and during the take-off The report noted that both the pilots in charge had an adequate rest period before operating the AI171 that crashed just 31 seconds after taking off. Apart from this, the crew of the flight were also found to be fit while operating the flight. When it comes to the take-off, the weights on the aircraft at that time were within allowable limits. 'There was no 'Dangerous Goods' on the aircraft,' the report said. 'Taxi clearance was received and the aircraft taxied from the bay to Runway 23 via Taxiway R4.' The report mentioned that the plane achieved the maximum recorded airspeed of 180 Knots. Soon after this, 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. Hence, both engines began to decrease take-off values as the fuel supply to the engines was cut off, which ultimately led to the crash. STORY CONTINUES BELOW THIS AD It is pertinent to note that the report released by India's Aircraft Accident Investigation Bureau is a preliminary one, and the case is now being further investigated.

How Air India's Dreamliner flight ended in disaster: A second-by-second timeline
A preliminary report into the crash of the Air India Boeing 787 Dreamliner in Ahmedabad that killed 260 people last month reveals that both of the aircraft's engines were starved of fuel almost simultaneously, just moments after takeoff. The findings, released Saturday by Indian aviation authorities, provide the most detailed account of the incident on June 12. Below is a second-by-second reconstruction of events leading up to the crash, based on the report: 11:17 am: Air India Dreamliner VT-ANB lands in Ahmedabad from New Delhi as flight AI423. 1:18:38 pm: The aircraft is observed departing from Bay 34 at the airport. 1:25:15 pm: The crew requests taxi clearance, which is granted by air traffic control. The aircraft begins taxiing toward Runway 23 via Taxiway R4, backtracks, and lines up for departure. 1:32:03 pm: The flight is transferred from ground control to tower control. 1:37:33 pm: Takeoff clearance is issued. 1:37:37 pm: The aircraft begins its takeoff roll. 1:38:39 pm: The aircraft lifts off. Investigators note that the air/ground sensors transition to air mode, consistent with liftoff. 1:38:42 pm: The aircraft reaches a maximum airspeed of 180 knots. Immediately after, both Engine 1 and Engine 2 fuel cutoff switches transition from 'RUN' to 'CUTOFF' positions, one after the other with a one-second gap. 'The Engine N1 and N2 began to decrease from their take-off values as the fuel supply to the engines was cut off.' One of the pilots is heard asking the other why did he cutoff. The other pilot responded that he did not do so. Airport CCTV footage shows the Ram Air Turbine (RAT) deploying during the initial climb, shortly after liftoff. 'The aircraft started to lose altitude before crossing the airport perimeter wall,' the investigation noted. 1:38:47 pm: Both engines' values drop below minimum idle speed. The RAT's hydraulic pump begins supplying hydraulic power. 1:38:52 pm: Engine 1's fuel cutoff switch is moved back from 'CUTOFF' to 'RUN.' 1:38:56 pm: Engine 2's fuel cutoff switch is similarly reset to 'RUN.' The probe report reads: 1:39:05 pm: One of the pilots issues a distress call: 'MAYDAY MAYDAY MAYDAY.' 1:39:11 pm: Data recording from the aircraft stops. 1:44:44 pm: Crash fire tenders leave the airport premises for rescue and firefighting efforts.
