Overview

• Cockpit voice recordings capture pilots’ surprise over sudden fuel cutoff when one asked “Why did you cut off?” and the other denied initiating it.
• Flight data shows both engine fuel control switches moved from RUN to CUTOFF within one second, triggering dual-engine shutdown moments after takeoff.
• Automatic deployment of the Ram Air Turbine and a mayday call confirm total loss of hydraulic and electrical power before the aircraft crashed.
• Investigators have found no signs of fuel contamination or design defects in the Boeing 787-8 or GE engines and regulators have held off on safety directives.
• Ongoing analysis of black box data, fuel samples and system components continues with support from Boeing, the NTSB and FAA ahead of a final report due soon.
