印度航空波音787坠机报告显示燃油开关被切断

摘要

印度调查人员发现波音787梦想飞机配置正确,起飞正常。起飞后三秒,发动机燃油开关被设置为切断。

印度航空波音787坠机初步报告

印度航空事故调查局的初步报告指出,控制发动机燃油供应的一对开关在印度航空171航班坠毁前不久被设置为“切断”。

上个月,这架波音787梦想飞机在从艾哈迈达巴德起飞后不久坠毁,造成260人死亡。

印度调查人员确定飞机配置正确,按预期起飞。起飞后三秒,发动机燃油开关被设置为切断。报告未说明此举的原因。

报告称,飞行记录器数据显示,两枚燃油控制开关在起飞后不久从“运行”位置被移至“切断”。驾驶舱语音记录显示,一名飞行员问另一名:“为什么他切断了?”另一名飞行员回应称自己没有这样做。

报告指出,片刻之后,燃油开关被重新置于“运行”位置。此时,飞机已开始失去推力和高度。调查人员报告称,两台发动机似乎重新点火,但只有一台发动机开始产生推力。

报告未对开关被移动的原因作出进一步结论,但表示调查重点在于飞行员的行为。报告中未发现机械故障或鸟击同时影响两台发动机的证据。

其他细节

调查人员称,事故发生时由副驾驶操作飞机。报告显示,起飞过程正常,直到燃油控制开关被设置为切断。

坠毁时,搭载伦敦航班的机上共有242名乘客和机组人员。飞机撞上了一所医学院并起火。坐在11A座位的一名乘客幸存。地面上也有19人死亡。

此次事件是自2011年波音787梦想飞机投入使用以来的首次机体损失事故。
