What Does the Preliminary Report Reveal About the Air India Plane Crash?

Synopsis
Key Takeaways
- Preliminary findings do not confirm the crash cause.
- Critical loss of engine thrust occurred.
- Final investigation reports often differ from preliminary ones.
- AAIB to conduct further technical analysis.
- Final report due in 12 months.
New Delhi, July 13 (NationPress) The preliminary assessment regarding the Air India Boeing 787 Dreamliner incident in Ahmedabad does not provide sufficient information to ascertain the definitive cause of the tragedy. The former Director of the Aircraft Accident Investigation Bureau (AAIB), Group Captain Aurobindo Handa, emphasized that it is premature for investigators to form conclusions at this point.
The Air India flight AI171 tragically crashed mere seconds after takeoff, colliding with a medical college hostel building. This catastrophic event resulted in the loss of 241 passengers and crew members aboard the aircraft, along with another 19 individuals on the ground.
A preliminary report issued by the AAIB on Saturday indicated that both engines experienced a loss of thrust due to the fuel cut-off switches transitioning from the ‘RUN’ to the ‘CUTOFF’ position. However, insights from the cockpit voice recorder suggest that one pilot communicated to the other that he did not deactivate the fuel control switches. The switches were reportedly returned to the RUN position just prior to the crash.
Handa noted that while the report outlines a factual timeline, it does not ascertain what initiated the failure. “Although the report has been published, it merely presents the facts of what transpired in those critical 30 seconds. It lacks conclusive evidence,” he remarked during a panel discussion on NDTV Profit.
He further highlighted that preliminary and final conclusions in aviation accident investigations often differ significantly, necessitating a more thorough technical examination. “Our experience shows that initial findings and the eventual ones frequently vary across numerous investigations,” he added.
Handa mentioned that the AAIB is likely to employ a process of elimination to rule out operational systems before identifying the most probable cause. The final report is mandated to be submitted within 12 months, as per guidelines set by the International Civil Aviation Organisation.
Union Civil Aviation Minister Ram Mohan Naidu also stated on Saturday that the AAIB's report on the Air India crash is based on preliminary findings and urged caution against premature conclusions until the final report is published.
