初步报告显示手动切断燃油导致印度航空171航班坠毁

摘要

对印度航空171航班坠毁的初步调查显示,两台发动机在燃油供应被手动切断后同时失去动力,但关于如何及为何发生此事仍有疑问。此次灾难造成260人死亡,调查仍在进行中,官员们对调查结果持续展开讨论。

调查人员发布了关于印度航空171航班灾难的初步调查结果。该航班于2025年6月12日从艾哈迈达巴德起飞后不久坠毁,造成260人死亡。飞机事故调查局(AAIB)报告称,两台发动机几乎同时因燃油供应被手动切断而失去动力,导致飞机在撞击前无法恢复动力。

此次坠机导致机上242名乘客和机组人员几乎全部遇难,仅有一人生还,地面也造成了额外的伤亡。视频显示,飞机起飞正常,但随后迅速下降,坠入靠近一所医学院的居民区。

AAIB的初步报告确定,两台发动机的燃油控制开关在起飞后不久被从“运行”位置切换至“切断”位置,这一操作需要有意为之,因为开关设有内置安全机制。检查未发现开关或其锁定机制存在机械故障,也无该机型或印度航空其他787飞机存在相关问题的历史记录。报告指出,开关被迅速连续关闭,约九秒后又恢复至原位,但发动机未能及时重新启动,未能避免坠机。

报告中包含的一段驾驶舱对话显示,一名飞行员询问另一名为何切断燃油,第二名飞行员否认责任。AAIB未公布完整驾驶舱录音或对话全文,引发部分飞行员协会和评论员批评,警告不要过早下定论。

调查重点 reportedly 放在机长苏米特·萨巴瓦尔(Sumeet Sabharwal)身上,他拥有超过15,000小时飞行经验,及副驾驶克莱夫·昆德(Clive Kunder),飞行时长3,400小时。媒体报道涉及萨巴瓦尔的个人历史,但印度航空母公司塔塔集团表示其近期健康状况正常,否认其近期有精神健康休假的说法。

此次坠机发生在印度航空正经历重大重组之际,同时波音公司也持续面临飞机安全的审查。多家飞行员组织批评初步报告,呼吁在调查完成前不要轻易归咎责任。AAIB表示调查仍在进行中,目前尚未发布新的安全建议。

事实核查

使用外部来源和数据库核实文章的事实。

✓
Confirmed

Investigators have released initial findings into the Air India flight 171 disaster, which claimed 260 lives when a Boeing 787 crashed shortly after takeoff from Ahmedabad on June 12, 2025.

✓
Confirmed

The Aircraft Accident Investigation Bureau (AAIB) reported that both engines lost power almost simultaneously due to the manual cutoff of the fuel supply, a sequence that left the aircraft unable to recover before impact.

✓
Confirmed

The crash resulted in the deaths of nearly all 242 people on board, with only one survivor, and caused further casualties and injuries on the ground.

✓
Confirmed

Video footage showed the aircraft taking off normally before descending rapidly and crashing into a residential area near a medical college.

✓
Confirmed

The AAIB's preliminary report determined that the fuel control switches for both engines were moved from 'run' to 'cutoff' just after takeoff, a process that requires deliberate action due to built-in safety mechanisms.

✓
Confirmed

Inspections found no mechanical faults with the switches or their locking mechanisms, and no history of related issues on this or other Air India 787s.

✓
Confirmed

A cockpit exchange included in the report indicated that one pilot asked the other why the fuel had been cut off, with the second pilot denying responsibility.

✓
Confirmed

The AAIB has not released full cockpit recordings or a direct transcript of the exchange, leading to criticism from some pilot associations and commentators who caution against premature conclusions.
