Engine 2, meanwhile, managed to relight but failed to arrest the core speed deceleration and continued to reintroduce fuel in repeated attempts to stabilise.The report states that at approximately 13:38:42 IST (08:08:42 UTC), the aircraft reached a maximum speed of 180 knots indicated airspeed (IAS). Immediately afterward, both Engine 1 and Engine 2 fuel cutoff switches transitioned from ‘Run’ to ‘Cutoff’.Shortly thereafter, Engine 1's fuel cutoff switch moved back from ‘Cutoff’ to ‘Run’ at 13:38:52 IST (08:08:52 UTC), followed by Engine 2's switch transitioning to ‘Run’ at 13:38:56 IST (08:08:56 UTC). Rising Exhaust Gas Temperatures (EGT) were observed in both engines, indicating relight activity.Cockpit voice recordings captured a moment of confusion between the pilots. One pilot was heard asking, “Why did you cut off?” The other responded, “I did not do so.”The AAIB report also revealed that both engines' N2 values had dropped below the minimum idle speed, according to data retrieved from the Engine and Flight Recorder (EAFR).However, the aft EAFR was found to be substantially damaged in the incident and could not be downloaded using conventional methods, the agency said.The investigation remains ongoing, and the AAIB is expected to publish further conclusions in its final report.<a href="https://www.hindustantimes.com/india-news/aaib-releases-preliminary-report-on-air-india-plane-crash-in-ahmedabad-report-101752263646478.html" target="_blank">https://www.hindustantimes.com/india-news/aaib-releases-preliminary-report-on-air-india-plane-crash-in-ahmedabad-report-101752263646478.html</a></blockquote>
