Overview

• Investigators have matched cockpit audio to identify the co-pilot as the questioner and are focusing suspicion on Captain Sumeet Sabharwal for the near-simultaneous fuel cutoff.
• An AAIB interim report released July 11 confirmed that both Boeing 787 engines lost fuel supply in under a second, causing immediate total power failure.
• Global audits of Boeing 787 and 737 fuel-cutoff switches, based on a non-mandatory 2018 FAA advisory, have detected no mechanical faults to date.
• Teams are integrating cockpit voice recordings with flight-data, medical records and maintenance logs to determine if the shutdown was intentional.
• U.S. safety officials are urging Indian authorities to involve criminal investigators should further evidence point to deliberate action.
