波音,联邦航空局检查停飞的737 Max飞机的线路

2020-1-7 12:46

华盛顿——波音公司和美国联邦航空管理局(FAA)周日证实,他们正在审查一个线路问题,该问题可能导致停飞的737max客机出现短路。


波音公司发言人戈登·约翰德罗周日表示,这家美国飞机制造商“确认这个问题是严格程序的一部分,我们正在与联邦航空局合作进行适当的分析。”现在推测这项分析是否会导致任何设计上的改变还为时过早。


据《纽约时报》报道,波音公司正在评估两束电线是否靠得太近,这可能导致短路,如果飞行员没有做出适当反应,还可能导致飞机坠毁。


美国联邦航空管理局周日在一份声明中表示,该机构和波音公司“正在分析最近对波音737 Max拟议修改的审查结果”。该机构补充说,它将“确保在这一过程中发现的所有安全相关问题得到解决”。


波音公司一名官员说,该公司目前正在制定一项计划,如有必要将电线束分开,并进行广泛的分析,以确定在真实世界中是否会发生电气故障。


官员们表示,美国联邦航空管理局已指示波音公司在12月完成审计。官员们补充说,线路问题可能会推迟Max的回归。路透社此前曾报道称,美国联邦航空局至少要到明年2月才可能批准这架飞机,可能要到明年3月或更晚才会批准。


美国联邦航空管理局(FAA)认为这一布线问题可能是“灾难性的”。一位公司官员说,屏蔽、绝缘和断路器等其他保护措施可能会防止短路。


在5个月内发生两起导致346人死亡的致命空难后,波音公司(Boeing)旗下最畅销的737 Max于今年3月停飞,此后该公司将于本月停止生产这款飞机。


上个月,波音公司(Boeing)董事会解除了首席执行官丹尼斯•穆伦伯格(Dennis Muilenburg)的职务,原因是该公司多次未能控制住事故的影响,而这些事故损害了该公司在航空公司和监管机构中的声誉。


这场危机使波音公司损失了90亿美元,并损害了供应商和航空公司。


波音正在努力修补与美国和国际监管机构的关系,它需要赢得这些关系,才能让这架飞机重返天空。


另外,官员们周日表示,美国和欧洲的监管机构预计将于本周返回爱荷华州,对去年没有完成的737 Max的软件文档审计进行审查。美国联邦航空管理局(FAA)和欧盟航空安全局(European Union Aviation Safety Agency)定于本周在西雅图开会,然后于下周返回位于爱荷华州锡达拉皮兹的罗克韦尔柯林斯(Rockwell Collins)工厂,对审计结果进行审核。

 

WASHINGTON-Boeing and the US Federal Aviation Administration, or FAA, confirmed on Sunday that they are reviewing a wiring problem that could potentially cause a short circuit on the grounded 737 Max jets.

Boeing spokesman Gordon Johndroe said on Sunday the US plane-maker "identified this issue as part of that rigorous process, and we are working with the FAA to perform the appropriate analysis. It would be premature to speculate as to whether this analysis will lead to any design changes".

The New York Times reported Boeing is reviewing whether two bundles of wiring are too close together, which could lead to a short circuit and potentially result in a crash if pilots did not respond appropriately.

The FAA said in a statement on Sunday the agency and company "are analyzing certain findings from a recent review of the proposed modifications to the Boeing 737 Max". The agency added it will "ensure that all safety related issues identified during this process are addressed".

Boeing is currently working on a plan that would separate the wiring bundles if necessary and conducting extensive analysis to establish if an electrical fault could occur in a real-world scenario, a company official said.

Officials said the FAA had directed Boeing to complete an audit in December. The wiring issue could push back the return of the Max, the officials added. Reuters has reported previously that the FAA is not likely to approve the plane until at least February and might not until March or later.

The FAA flagged the wiring issue as potentially "catastrophic." It is possible other protections like shielding, insulation and circuit breakers could prevent the short circuit, a company official said.

Boeing will halt production of the 737 Max this month following the grounding in March of its best-selling plane after two fatal crashes in five months killed 346 people.

Last month, Boeing's board fired Dennis Muilenburg as chief executive after repeatedly failing to contain the fallout from the crashes that tarnished the company's reputation with airlines and regulators.

The crisis has cost Boeing $9 billion, and has hurt suppliers and airlines.

Boeing is struggling to mend relations with the US and international regulators that it needs to win over to get the jet back in the air.

Separately, US and European regulators are expected to return to Iowa this week to review a software documentation audit of the 737 Max that was not completed last year, officials said on Sunday. The FAA and the European Union Aviation Safety Agency are scheduled to meet in Seattle this week and then return to the Rockwell Collins facility in Cedar Rapids, Iowa, next weekend to review the audit.
