美国航空航天与国防承包商L3Harris周六表示，在周五发生全国性航班中断后，该公司已完成支持美国领空通信基础设施升级的逾70%。
US aerospace and defense contractor L3Harris on Saturday said it has completed more than 70% of a communications infrastructure upgrade supporting US airspace, following a nationwide flight disruption on Friday.
该公司称，这一现代化项目由联邦航空管理局和电信合作伙伴协同推进，内容是将老化的铜缆替换为光纤技术。
The company said the modernization project, carried out in coordination with the Federal Aviation Administration and telecommunications partners, involves replacing aging copper lines with fiber-optic technology.
L3Harris在美国社交媒体平台X上发布声明称，此次转换旨在现代化支持美国空中交通运行的通信网络，强调“安全与可靠性是我们的最高优先级”。该声明发布之际，当局正在调查一起技术故障，该故障迫使联邦航空管理局下令全国航班停飞，导致数千名乘客滞留，航空公司难以恢复航班时刻表。
In a statement on US social media company X, L3Harris said the conversion was intended to modernize the communications network supporting US air traffic operations, emphasizing "safety and reliability as our highest priorities." The announcement came as authorities investigated a technical disruption that forced the Federal Aviation Administration to halt flights nationwide, stranding thousands of passengers and leaving airlines struggling to restore their schedules.
交通部长肖恩·达菲表示，事故似乎源于一处偏远设施的例行维护，当时正在将铜质电信线路更换为光纤连接。官员尚未确定是承包商失误、安装缺陷还是设备故障导致了中断。
Transportation Secretary Sean Duffy said the incident appeared to have originated during routine maintenance at a remote facility where copper telecommunications lines were being replaced with fiber-optic connections. Officials have not determined whether contractor error, faulty installation or defective equipment caused the disruption.
L3Harris表示，正配合航空监管机构的调查，以查明导致停运的原因。
L3Harris said it was cooperating with the aviation regulator's investigation to establish what led to the outage.
该公司还承认了此次事件的更广泛后果，称严肃对待全国性停飞令及其对“旅客、航空公司和空中交通运行”的影响。联邦航空管理局称系统已恢复稳定，而航空公司仍在努力恢复正常运营。
The company also acknowledged the broader consequences of the incident, saying it took the nationwide ground stop and its impact on "travelers, airlines and air traffic operations seriously." The Federal Aviation Administration said the system returned to stability, while airlines continued working to restore normal operations.
