New technical data released by the U.S. National Transportation Safety Board (NTSB) has brought fresh scrutiny to the 2022 China Eastern Airlines Flight MU5735 disaster. While the Civil Aviation Administration of China (CAAC) has yet to publish a final report, NTSB findings indicate that the Boeing 737-800 experienced manual fuel shut-off activation and autopilot disengagement immediately preceding its fatal descent.
The data shows that both engine fuel switches were moved from the run position to cutoff, a mechanical process requiring deliberate pilot action. Subsequent inputs to the control column suggest a manual override of the flight path. These findings conflict with the official narrative maintained by Chinese authorities, who have cited national security concerns to explain the delay in final reporting.
The incident has revived industry discussions regarding cockpit security and mental health protocols, drawing comparisons to the 2015 Germanwings tragedy. Although the flight included a third pilot, the rapidity of the control inputs highlights the challenge of maintaining cockpit intervention safety. Global aviation stakeholders remain concerned that the ongoing lack of transparency from the CAAC hinders the industry’s ability to implement critical safety improvements.
