Both engines of Air India Flight 171 shut down almost after take-off: Preliminary report
A preliminary report of the investigation has confirmed that both engines of the plane did shut down within seconds of take-off.
An excerpt from the report noted this:
"The aircraft achieved the maximum recorded airspeed of 180 Knots IAS (Indicated Airspeed) at about 08:08:42 UTC (Universal Time - 1:38 pm IST) 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 01 sec.
"The Engine N1 and N2 began to decrease from their take-off values as the fuel supply to the engines was cutoff.
"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 report doesn't identify which pilot said what, but states, according to the BBC, that the switches were then moved back into their normal inflight position.
This would have automatically started the process of reviving the engines.
The report observes that one engine was "in the process of regaining thrust at the time the aircraft crashed. The other was relit but was not yet regaining thrust".
The preliminary report also did not find any "significant fault with the plane or its engines".
It noted that "at this stage of investigation, there are no recommended actions to B787-8 and/or GE GEnx-1B engine operators and manufacturers, suggesting that no significant fault has been found with the plane or its engines."
The report went on to underline that no conclusions have been drawn and that the investigations are continuing.
The lone 'miracle' survivor of the crash was Vishwashkumar Ramesh, a British national.
One hundred sixty nine Indians, 52 Britishers, seven Portuguese nationals, one Canadian and 12 crew members were among the 241 dead.

Suspected snag: Air India Thiruvananthapuram-Delhi flight diverts to Chennai
Representative image (ANI) NEW DELHI: Air India's Thiruvananthapuram (TRV)-Delhi flight AI 2455 on Sunday night with several MPs among the passengers safely diverted to Chennai following a suspected snag. On its approach to Chennai, the Airbus A320neo ((VT-TNL) was given a go-around by the air traffic control (ATC) — meaning asked to abort landing and then touch down in second attempt — which the pilots executed safely. However, the announcement of the flight diverting due to a snag, enroute bad weather and then the go-around added to the anxiety of passengers. Congress MP K C Venugopal who represents Alappuzha in Lok Sabha was among the parliamentarians on board. He said on X early Monday morning: 'AI 2455 from Trivandrum to Delhi, carrying myself, several MPs, and hundreds of passengers, came frighteningly close to tragedy. What began as a delayed departure turned into a harrowing journey. Shortly after take-off, we were hit by unprecedented turbulence. About an hour later, the captain announced a flight signal fault and diverted to Chennai.' 'For nearly two hours, we circled the airport awaiting clearance to land, until a heart-stopping moment during our first attempt — another aircraft was reportedly on the same runway. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Free P2,000 GCash eGift UnionBank Credit Card Apply Now Undo In that split second, the captain's quick decision to pull up saved every life on board. The flight landed safely on the second attempt. We were saved by skill and luck. Passenger safety cannot depend on luck. I urge DGCA and aviation ministry to investigate this incident urgently, fix accountability, and ensure such lapses never happen again,' Venugopal added. Aircraft routinely go around for safety reasons due to a number of factors like unstabilised approach or a plane/vehicle being on the runway it is supposed to land on. Air India denied that AI 2455 was asked to go around because there was another aircraft on the runway. An AI spokesperson said: 'The flight crew of AI2455 operating from Thiruvananthapuram to Delhi on August 10 made a precautionary diversion to Chennai due to a suspected technical issue and given the weather conditions enroute. The flight landed safely in Chennai, where the aircraft will undergo the necessary checks. We regret the inconvenience caused to affected passengers…. At AI, safety of our passengers and crew remain top priority. ' Congress MP for Virudhunagar Manickam Tagore B who as also on board said on X: 'Shocked & shaken. Air India AI 2455 from TRV to Delhi, carrying MPs & hundreds of passengers, narrowly escaped disaster today — turbulence, flight signal fault, and a near runway collision in Chennai…. Passenger safety cannot rely on luck. We demand answers & action now.' Replying to him, AI said: '…diversion to Chennai was precautionary, due to a suspected technical issue and poor weather conditions. A go-around was instructed by Chennai ATC during the first attempted landing, not because of the presence of another aircraft on the runway. Our pilots are well-trained to handle such situations, and in this case, they followed standard procedures throughout the flight…' Air India arranged another Airbus A320neo, VT-TQE, which flew the passengers from Chennai to Delhi as AI 2455. The usual flying time of AI 2455 (TRV-Delhi) is 3.5 hours with a schedule departure time 7.15 pm. According to flight tracking sites, it took off with a slight delay on Sunday at 8 pm & landed in Chennai at 10.39 pm. The alternate aircraft took off from Chennai at 1.40 am & landed in Delhi at about 4 am. Seasoned aviators say while AI 2455 had a routine suspected snag, passenger anxiety levels have expectedly been higher post the deadly June 12 AI 171 crash in Ahmedabad and subsequent incidents.
