UPS和FedEx在2025年11月6日UPSLouisville中心发生致命坠毁事件, 造成14人死亡后, 联合50多架MD-11型货机停飞。 UPS and FedEx have grounded their combined fleet of over 50 MD-11 cargo planes following a deadly crash at UPS’s Louisville hub on November 6, 2025, that killed 14 people. MD-11是1991年建造的,在起飞时起火,引擎失灵,驾驶舱在要求推力后约37秒钟发出警报后坠落到一个仓库区。 The MD-11, built in 1991, caught fire on takeoff, lost an engine, and crashed into a warehouse district after a cockpit alarm sounded about 37 seconds after thrust was requested. 国家运输安全委员会正在进行调查,尚未确定原因,尽管警报可能发出发动机起火信号。 The National Transportation Safety Board is investigating, with no cause yet determined, though the alarm likely signaled an engine fire. 两个承运人均援引制造商的建议作为理由,尽管1997年收购麦克唐纳道格拉斯的波音公司没有解释其指导意见。 Both carriers cited manufacturer recommendations in the grounding, though Boeing, which acquired McDonnell Douglas in 1997, did not explain its guidance. 该飞机在坠机前在圣安东尼奥进行了一个月多的维修。 The aircraft had undergone over a month of maintenance in San Antonio prior to the crash. 不久之后,UPS在其路易斯维尔中心恢复了有限的业务。 UPS resumed limited operations at its Louisville hub shortly after.
