近日，美国国家运输安全委员会（NTSB）发布初步调查报告，披露了一起波音737 MAX 9型客机发生的内嵌式应急门掉落事故。报告显示，事故客机在出厂时缺失了关键的固定螺栓。这些螺栓对固定内嵌式应急门具有关键作用，它们的缺失可能埋下了安全隐患。
据了解，今年1月，这架波音737 MAX 9客机在飞行过程中，内嵌式应急门突然掉落。事故发生后，美国国家运输安全委员会展开了调查。调查人员在对飞机进行检查时发现，原本应该固定应急门的螺栓不见了。
波音公司对此表示，他们将全力配合调查，并尽快解决这一问题。该公司强调，飞机在出厂前会进行严格的质量把控，但此次事件可能是由于个别失误造成的。
目前，调查尚未结束，美国国家运输安全委员会将继续关注此事。 missing bolts, Boeing, safety concerns
The recent preliminary investigation report released by the US National Transportation Safety Board (NTSB) disclosed an incident involving the falling of an embedded emergency door on a Boeing 737 MAX 9 aircraft. The report showed that the aircraft lacked crucial bolts during production. These bolts are crucial for fixing the embedded emergency door, and their absence may have posed a safety hazard.
It is understood that in January this year, the Boeing 737 MAX 9 aircraft experienced a sudden loss of the embedded emergency door during flight. After the accident, the NTSB launched an investigation. During the inspection, the investigators found that the bolts supposed to secure the emergency door were missing.
Boeing stated that they will fully cooperate with the investigation and address the issue promptly. The company emphasizes that strict quality control is in place before aircraft delivery, but this incident may have been caused by individual errors.
The investigation is ongoing, and the NTSB will continue to follow up on the matter.
