Overview

• The AAIB’s 15-page preliminary report shows both engine fuel control switches moved from RUN to CUTOFF within one second of liftoff, starving the engines of fuel
• Cockpit voice recordings capture one pilot asking why the fuel was cut off and the other replying that he did not perform the action
• Investigators ruled out bird strikes and fuel contamination and documented automatic deployment of the Ram Air Turbine, confirming a complete power failure
• The report cites a 2018 FAA advisory on potential disengagement of the fuel switch locking feature, noting that the recommendation was non-mandatory and unheeded
• No liability has been assigned and both Air India and Boeing say they are fully cooperating as the final AAIB report is due by June 12, 2026
