Overview

• The preliminary interim report finds that both fuel supply switches in the cockpit were switched off three seconds after liftoff, triggering a steep drop in engine thrust.
• Cockpit voice recordings capture one pilot asking “Why did you switch it off?” and the other denying any action, highlighting confusion over crew involvement.
• Initial technical examinations ruled out structural faults, engine malfunctions, significant weather anomalies and bird strikes as contributing factors.
• Simulations by a Boeing 787 training pilot could not reproduce a dual-engine shutdown from electrical failure, reinforcing investigative focus on the unexplained switch-off.
• India’s Directorate General of Civil Aviation continues detailed analysis of flight data recorders and wreckage fragments, with no formal safety recommendations issued to date.
