华盛顿8月27日路透电 —— 美国国家运输安全委员会周四表示，8月4日搭载美国总统唐纳德·特朗普的军用直升机在距离客机过近的安全事件发生前，机组人员并未联系空中交通管制部门。
这起涉及从里根华盛顿国家机场起飞的客机的事件，引发了外界质疑：为何在海军一号在场的情况下，这架客机仍被允许起飞——通常该时段商业航班会暂停。

国家运输安全委员会表示，海军一号机组人员至少两次尝试向管制员发出要求的三分钟起飞前通知，但因通信问题受阻。委员会还称，机组人员也曾尝试通过联合基地阿纳卡斯蒂亚-博林的直升机设施联系管制员，但同样未能成功。
联邦航空管理局局长布莱恩·贝德福德周二表示，该事件发生后，该局已重新安置了天线并修改了一项程序。国家运输安全委员会称，天线重新安置后的检查未发现任何通信问题。
国家运输安全委员会还披露曾存在其他通信问题。7月30日，海军一号机组与空中交通管制人员会面，管制人员当时提出“要讨论近期有关他们未收到要求的三分钟起飞呼叫的报告所引发的担忧”。
国家运输安全委员会表示，海军一号机组称通信“时断时续”。
联邦航空管理局规定，机场周边航空器的水平间隔至少需保持1.5英里（2.4公里），垂直间隔至少需保持500英尺（152米）。国家运输安全委员会称，海军一号与涉事客机某一时刻的横向间隔仅为0.82海里，垂直间隔为700英尺。
涉事的Envoy航空3742号航班为巴西航空工业E170支线客机，原定飞往佛罗里达州彭萨科拉。事件发生时，另一架支线航班共和航空4700号航班距离里根机场3英里，出于谨慎考虑被改道。
2025年1月一架美国航空支线客机与一架陆军直升机在空中相撞后，联邦航空管理局对华盛顿里根机场周边的直升机运营实施了永久性限制。

WASHINGTON, Aug 27 (Reuters) – The crew of a military helicopter carrying President Donald Trump that came too close to a passenger jet on August 4 failed to reach air traffic controllers before departing, the National Transportation Safety Board said on Thursday.
The incident involving a plane departing Reagan Washington National Airport raised questions about why the passenger airplane was allowed to depart while Marine One was nearby, a time when commercial traffic is typically halted.

The NTSB said the Marine One crew at least twice attempted to give controllers a required three-minute notice of departure but were hampered by communications issues. The NTSB said the crew also sought to contact controllers through the helicopter facility at Joint Base Anacostia-Bolling, which was also unsuccessful.
On Tuesday, the head of the Federal Aviation Administration, Bryan Bedford, said the agency relocated an antenna and changed a procedure after the incident. The NTSB said checks made after the relocation have shown no communications issues.
The NTSB also disclosed there had been other communication issues. On July 30, Marine One and air traffic control staff met and controllers sought “to discuss concern with recent reports of their not receiving the required 3 minute to liftoff call,” the NTSB said.

The Marine One crew said communications “had been spotty,” the NTSB said.
FAA rules require aircraft to remain separated by at least 1.5 miles (2.4 km) horizontally and 500 feet (152 m) vertically around airports. The NTSB said Marine One and the plane were at one point separated by 0.82 nautical mile laterally and 700 feet vertically.
Envoy Air 3742, an Embraer EMBJ3.SA E170 regional jet, was bound for Pensacola, Florida. Another regional flight, Republic 4700, was 3 miles from Reagan during the incident and was rerouted out of caution.
The FAA imposed permanent restrictions on helicopter operations around Washington’s Reagan Airport after the January 2025 midair collision between an American Airlines regional jet and an Army helicopter.
