Boeing 737 Max Jets Face New Safety Concerns Over Jamming Pedals As Investigators Point Out Moisture Leakage Risks
Safety investigators have recently issued urgent recommendations to Boeing Co (NYSE:BA) and the Federal Aviation Administration following the discovery of a potential safety issue with the 737 Max jets. The issue pertains to the pedals used by pilots to steer the aircraft on runways, which can reportedly become jammed due to moisture leakage.
安全调查人员最近向波音公司（纽交所: 波音）和联邦航空管理局发出紧急建议，因为他们发现737 Max飞机存在潜在的安全问题。问题涉及飞行员用于在跑道上驾驶飞机的踏板，据称可能由于水分泄漏而卡住。
What Happened: The National Transportation Safety Board has discovered that moisture can seep into the rudder assembly and freeze, causing the pedals to jam. This finding was the result of an investigation into an incident involving a United Airlines Holdings Inc (NASDAQ:UAL) plane earlier this year.
发生了什么：国家运输安全委员会发现水分可以渗入方向舵总成并结冰，导致踏板卡住。这一发现是对今年早些时候涉及联合航空控股公司（纳斯达克: 联合航空）飞机事件的调查结果。
The NTSB has found that the faulty work affected at least 353 actuators installed on some Max jets and older 737s. The NTSB has advised Boeing to modify flight manuals to eliminate advice that pilots use maximum pedal force to overpower a jammed rudder, as this could cause sudden rudder movement and potentially lead the plane to go off the runway.
国家运输安全局发现，有缺陷的工作影响了至少353个安装在部分Max飞机和老式737上的致动器。国家运输安全局建议波音修改飞行手册，取消飞行员使用最大踏板力量来克服卡住方向舵的建议，因为这可能导致方向舵突然移动，潜在地导致飞机驶离跑道。
Why It Matters: This latest safety concern adds to the list of issues that have plagued the 737 Max jets. The aircraft were grounded worldwide in March 2019 following two fatal crashes that claimed 346 lives. The planes were allowed to return to service in November 2020 after Boeing made significant changes to the flight control system.
为什么重要：这一最新的安全问题增加了困扰737 Max飞机的问题清单。在2019年3月发生导致346人死亡的两起致命事故之后，这些飞机在全球范围内停飞。在波音对飞行控制系统进行重大更改后，这些飞机于2020年11月被允许重新投入服务。
Price Action: Boeing Co's stock closed at $154.58 on Thursday, up 1.55% for the day. In after-hours trading, the stock slightly increased 0.0065%. However, year to date, Boeing's stock has decreased by 38.60%, according to data from Benzinga Pro.
股价走势：波音公司的股价周四收盘价为154.58美元，上涨了1.55%。在盘后交易中，股价略微增加了0.0065%。然而，根据彭博财经专业版的数据，波音的股价年初以来已下跌了38.60%。
