达菲：FAA与海军陆战队一号团队正解决通信中断问题
美国运输部长肖恩·达菲周二表示，在上周总统唐纳德·特朗普的直升机与一架商业客机在里根国家机场附近险些相撞后，美国联邦航空管理局（FAA）官员正与海军陆战队一号团队合作解决通信问题。

根据周四发布的一份联邦初步报告，海军陆战队一号机组人员曾多次尝试通知里根国家机场，称特朗普总统的直升机将于8月4日准备起飞，但均未成功，随后该直升机与一架商业客机险些相撞。
美国国家运输安全委员会的初步报告显示，机组人员在从椭圆广场起飞前首次呼叫里根国家机场直升机管制频道时，信号未被接收到。第二次传输则“断断续续且完全无法识别”。
报告称，在未能联系上塔台后，海军陆战队一号机组人员试图通过阿纳卡斯蒂亚-博林联合基地的直升机设施转达所需的三分钟起飞预警，但同样未能成功。

2026年8月4日，唐纳德·特朗普总统在马里兰州安德鲁斯联合基地下海军陆战队一号直升机，登上空军一号。新报告显示，特朗普的直升机的无线电警告未被接收到。
此次未成功发出警告意味着里根国家机场的管制人员未能收到通知，也就无法要求他们在总统直升机起飞前暂停其他起飞操作。
相反，前往佛罗里达州彭萨科拉的巴西航空工业E-170型客机恩维航空3742号航班被允许从1号跑道起飞，此时特朗普正乘坐海军陆战队一号直升机离开白宫，按计划前往洛杉矶。
美国国家运输安全委员会表示，当海军陆战队一号从机场以北约2英里的椭圆广场起飞时，这架客机正开始初始爬升阶段。
美国联邦航空管理局的初步评估显示，两架飞机的横向间距约为0.82海里，垂直间距约700英尺。无人受伤，两架飞机均未受损，后续飞行均未出现其他事故。

恩维航空的机组人员表示，客机起飞后爬升加速时，空中交通防撞系统发出了“注意Traffic，注意Traffic”的警报。飞行员并未目视发现海军陆战队一号，但称在驾驶舱显示器上看到直升机位于他们飞机的右下方。
根据美国国家运输安全委员会的报告，该系统未发出解决咨询警报——即要求飞行员爬升或下降以避开其他飞机的更紧急指令。

报告称，海军陆战队一号最终在爬升至足够高度建立可靠通信后才联系上塔台。管制人员随后发出了交通预警，直升机机组人员立即报告已目视发现恩维航空的客机。
新发布的报告还显示，此类通信问题早在几天前就已被提出。

美国国家运输安全委员会称，7月30日，海军陆战队第一直升机中队（HMX-1）与里根国家机场塔台工作人员会面，讨论该区域的运行事宜。在此次会议中，HMX-1向管制人员表示，通信一直“时好时坏”。
管制人员也提出担忧，称HMX-1机组人员并不总是能在起飞前按要求提供三分钟预警。双方达成一致：如果直接无线电通信失败，直升机机组人员将使用备用方式联系塔台，包括通过其他飞机转达预警信息。

这正是海军陆战队一号机组人员在8月4日尝试的做法，但信息仍未成功传递。
美国联邦航空管理局的技术人员后来确定，无线电收发信站点与椭圆广场之间的视线覆盖范围不足——当时海军陆战队一号因白宫施工临时在椭圆广场运作。
报告称，美国联邦航空管理局随后将机场直升机管制频道使用的无线电设备从附近的居民区迁至里根国家机场的控制塔塔顶。

该机构随后对在椭圆广场附近运行的两架HMX-1飞机进行了无线电测试，称设备迁移后未发现任何缺陷。
美国联邦航空管理局和美国国家运输安全委员会本月早些时候开始对这起事件展开调查，此前曾将该事件描述为“短暂的间距不足”。
“根据我们初步的安全审查，出现了短暂的间距不足，之后两架飞机继续相互远离，”美国联邦航空管理局此前告诉福克斯新闻数字频道。
“在间距不足期间，空中交通管制员与商业航班飞行员和海军陆战队一号飞行员都保持着联系。”
美国国家运输安全委员会表示，虽然据估计两架飞机的水平间距不到1.5海里，但初步评估的700英尺垂直间距符合美国联邦航空管理局的适用标准。在相关的B级空域，标准要求要么保持1.5海里的横向间距，要么保持500英尺的垂直间距。

美国国家运输安全委员会表示，其正在继续审查监控数据，以计算并确认两架飞机之间的最近距离。
白宫此前表示，特朗普从未处于危险之中。
“海军陆战队一号的飞行员是世界上最优秀的飞行员之一，总统从未处于任何危险之中，”白宫发言人库什·德赛告诉福克斯新闻数字频道。
美国国家运输安全委员会告诉福克斯新闻数字频道，其初步报告“旨在呈现迄今收集到的事实信息”，并不包含“与可能原因相关的分析、结论或调查结果”。

“调查仍在进行中，除初步报告中包含的信息外，我们不会提供额外评论，”该机构表示，并补充道任何安全建议都将公开宣布，进一步的调查结果将通过其公开档案和最终报告程序发布。

Trump helicopter’s radio warnings went unheard before close call with passenger jet, report says

FAA, Marine One team fixing telecom issue after loss of separation: Duffy
Transportation Secretary Sean Duffy said Tuesday FAA officials are working with the Marine One team to resolve telecom issues after a loss of separation last week between President Donald Trump’s helicopter and a commercial aircraft near Reagan National Airport.
NEW You can now listen to Fox News articles!
Marine One’s crew made repeated but unsuccessful attempts to notify Reagan National Airport that President Donald Trump’s helicopter was preparing to depart Aug. 4 before it flew near a commercial passenger jet, according to a preliminary federal report released Thursday.
The National Transportation Safety Board’s preliminary report said the crew’s first call to Reagan National’s helicopter-control frequency before departing from the Ellipse was not received. A second transmission was “broken and completely unreadable.”
After failing to reach the tower, the Marine One crew tried to relay the required three-minute notification through the helicopter facility at Joint Base Anacostia-Bolling, but that effort was unsuccessful as well, according to the report.

The missed warning meant Reagan National controllers did not receive notice that would have required them to stop departures before the presidential helicopter lifted off.
Instead, Envoy Air Flight 3742, an Embraer E-170 bound for Pensacola, Florida, was cleared to take off from Runway 1 as Trump departed the White House aboard Marine One for a planned trip to Los Angeles.
The passenger jet was beginning its initial climb as Marine One departed the Ellipse, about 2 miles north of the airport, the NTSB said.
The FAA’s preliminary estimate found the aircraft came within about 0.82 nautical miles of one another laterally and roughly 700 feet vertically. No one was injured, neither aircraft was damaged and both flights continued without further incident.

The Envoy flight crew said the jet’s traffic-collision system announced, “Traffic, Traffic,” as the aircraft climbed and accelerated after takeoff. The pilots did not visually spot Marine One but said the helicopter appeared to the right and below their aircraft on the cockpit display.
The system did not issue a resolution advisory, a more urgent instruction telling pilots to climb or descend to avoid another aircraft, according to the NTSB report.

Marine One was eventually able to contact the tower after climbing high enough to establish reliable communications. Controllers then issued a traffic advisory, and the helicopter crew immediately reported having the Envoy jet in sight, the report said.
The newly released report also shows the communications concern had been raised just days earlier.

On July 30, Marine Helicopter Squadron One, known as HMX-1, met with Reagan National tower staff to discuss operations in the area. During that meeting, HMX-1 told controllers that communications had been “spotty,” the NTSB said.
Controllers had also raised concerns that HMX-1 crews had not always provided the required three-minute warning before takeoff. The two sides agreed that helicopter crews would use backup methods to reach the tower, including relaying the notification through another aircraft, if direct radio communication failed.

That is what Marine One’s crew attempted on Aug. 4, but the message still did not get through.
FAA technicians later determined there was not adequate line-of-sight coverage between the radio transmitter-receiver site and the Ellipse, where Marine One was temporarily operating during construction at the White House.
The FAA subsequently moved the radios used for the airport’s helicopter-control frequency from a nearby residential neighborhood to the top of Reagan National’s control tower, according to the report.

The agency later conducted radio checks with two HMX-1 aircraft operating near the Ellipse and reported no deficiencies after the equipment was moved.
The FAA and NTSB began reviewing the incident earlier this month and previously characterized the event as a “momentary loss of separation.”
“Based on our preliminary safety review, there was momentary loss of separation, after which the aircraft continued to move away from one another,” the FAA previously told Fox News Digital.
“The air traffic controller was in contact with both the commercial pilot and Marine One pilot during the loss of separation.”
While the aircraft were estimated to be less than 1.5 nautical miles apart horizontally, the NTSB said the preliminary estimate of 700 feet of vertical separation met the applicable FAA standard. In the relevant Class B airspace, the standard requires either 1.5 nautical miles of lateral separation or 500 feet of vertical separation.

The NTSB said it is continuing to review surveillance data to calculate and confirm the closest point between the two aircraft.
The White House previously said Trump was never in danger.
“Marine One flights are piloted by some of the best aviators in the world, and at no point was the president in harm’s way,” White House spokesman Kush Desai told Fox News Digital.
The NTSB told Fox News Digital its preliminary report “is intended to present the factual information developed to date” and does not contain “analysis, conclusions, or findings related to probable cause.”

“The investigation remains ongoing, and we are not providing additional comment beyond the information contained in the preliminary report,” the agency said, adding that any safety recommendations would be publicly announced and further findings would be released through its public docket and final report process.
