中国东方航空737客机坠毁事件：飞行员疑似人为切断双发，中方以国家安全为由隐瞒报告
2022年3月发生的中国东方航空MU5735航班坠毁事件，造成132人遇难。
美国国家运输安全委员会（NTSB）基于飞行记录仪数据分析显示，飞机在巡航高度时，飞行员将两台发动机的油量开关从“运行”状态切换到“截止”状态，且在随后飞机失去动力时，自动驾驶系统也被关闭，暗示可能存在人为破坏的迹象。
由于飞机失事后，中国民用航空局（CAAC）一直未发布最终事故报告，引发国际关注，并以国家安全为由拒绝信息公开。
NTSB通过信息公开申请（FOIA）公开了部分记录，但未保留副本。
目前，事故原因仍在调查中。

Four years after China Eastern Flight MU5735 plunged into the ground, China is withholding the accident report. Since it was a Boeing aircraft, the U.S. National Transportation Safety Board was involved in the investigation. They released their report on cockpit recordings in response to a FOIA. That was clearly not an accident – they could have withheld it or stalled – but they’re clearly frustrated with the Civil Aviation Administration of China. And the information we have makes it look like a clear case of intentional sabotage by one of the pilots.
The flight from Kunming to Guangzhou on March 21, 2022 killed all 132 people on board. The plane plunged quickly, air traffic controllers called the crew repeatedly and received no reply. China ever published a final accident report.
The NTSB report covers the cockpit voice recorder and flight data recorder downloads. It shows that while the 737 was cruising at 29,000 feet, the fuel switches for both engines moved from RUN to CUTOFF. The flight data recorder lost power when the number 2 engine cut at about 26,000 feet.
