机长关闭燃油开关！印度坠机事件：调查转向机组操作失误

Core Viewpoint - The preliminary investigation into the Indian Airlines crash indicates that the direct cause was the pilot's action of shutting off the fuel supply to both engines, leading to the aircraft's failure to maintain altitude and subsequent crash [2][4]. Group 1: Incident Details - The crash involved an Indian Airlines Boeing 787-8 aircraft shortly after takeoff from Ahmedabad, India, resulting in over 270 fatalities [4]. - Both black boxes from the aircraft have been recovered, and the investigation has shifted focus from technical failure to pilot error [3][4]. - The cockpit voice recording revealed a conversation between the pilots regarding the fuel supply switch, indicating confusion about the actions taken [4]. Group 2: Technical Analysis - The report highlighted that the fuel supply switches for each engine are equipped with locking mechanisms to prevent accidental changes [5]. - The process to open or close the fuel supply involves specific actions that make accidental operation unlikely, suggesting a deliberate action by the pilots [6]. - The fuel supply to the engines was cut off for approximately 10 seconds, during which the aircraft lost power and could not recover in time [4]. Group 3: Pilot Background - The captain, Sumit Sabharwal, had over 15,000 flight hours, with 8,596 hours on the Boeing 787, while the co-pilot, Clive Kundal, had 3,403 total flight hours, including 1,128 hours on the same aircraft [6].
