Overview

• The AAIB’s preliminary report rules out mechanical or design flaws in the Boeing 787-8 airframe and its GE GEnx-1B engines.
• Flight data recorder analysis shows both fuel control switches were moved from “Run” to “Cutoff” seconds after takeoff, causing immediate loss of thrust.
• Cockpit voice recordings capture one pilot asking “Why did you cut off the engines?” and the other responding “I didn’t,” leaving intent unresolved.
• Automatic deployment of the Ram Air Turbine confirmed the aircraft’s loss of primary electrical power following dual-engine shutdown.
• Boeing, GE Aerospace, and Indian investigators are collaborating on the inquiry, with a final report expected within 12 to 18 months.
