FAA Proposes Mandatory Maintenance Checks For Some Boeing 787 Dreamliners
The Federal Aviation Administration has proposed requiring The Boeing Company (NYSE:BA) to conduct maintenance record checks or inspections of some of its 787 Dreamliners after the company reported missing a test on a part to the main landing gear.
美国联邦航空局建议要求波音公司（NYSE:BA）对其部分787梦想客机的维护记录进行检查或检验，因为该公司报告称未测试起落架主轮上的部件。
The FAA has recommended a new airworthiness directive for all of Boeing's Model 787-8, 787-9, and 787-10 airplanes after Boeing reported that drag brace lower lock link assemblies, which lock landing gear into place for landing, were not inspected during manufacture, according to a document in the U.S. Federal Register.
根据美国联邦注册文件中的一份文件，波音报告称，在制造过程中，锁定起落架以备降落的拖撬下锁链组件未经检查，飞行安全局已建议所有波音787-8、787-9和787-10型号飞机制定一项新空气适航指令。
"The FAA is proposing this AD to address the unsafe condition on these products," the document said.
“美国联邦航空局提出了这项空气适航指令，以解决这些产品的不安全问题，”文件中说。
An investigation determined that the missed inspection was caused by "human error" isolated to a single technician.
调查发现，错过的检查是由一名技术人员独立造成的“人为错误”引起的。
"Undetected cracks could lead to fracture of the drag brace lower lock link assembly," the document stated.
“未发现的裂纹可能导致拖撬下锁链组件断裂，”文件中指出。
"This condition, if not addressed, could lead to MLG collapse, which could result in loss of directional control while the airplane is on the ground, with the potential for off-runway excursion or penetration of the wing box fuel tank."
“如果不加以解决，这种情况可能导致起落架折叠，从而在飞机在地面时失去方向控制，可能导致偏离跑道或侵入机翼油箱。”

The FAA estimated that the directive would affect 156 U.S.-registered airplanes, if adopted as proposed.
如果按照建议采纳，美国联邦航空局估计该指令将影响156架在美注册的飞机。
The missed inspection occurred after Boeing's 737 Max airplanes were grounded earlier this year for a second time after a door flew off during an Alaskan Airlines flight.
在阿拉斯加航空公司的一次飞行中，一扇门掉了下来后，波音的737MAX飞机今年再次被停飞。这次错过的检查是在此之后发生的。这些飞机此前曾在2019年3月至2020年12月期间停飞，因发生两起导致共计346人死亡的空难。
The planes were previously grounded from March 2019 to December 2020 after two crashes that killed a total of 346 people.
在7月，波音以47亿美元收购了Spirit Aerosystems，承认涉及两起致命飞机坠毁的刑事指控，并任命罗伯特·奥特伯格为新的首席执行官。
In July, Boeing acquired Spirit Aerosystems for $4.7 billion, pled guilty to criminal charges related to the two fatal plane crashes and appointed Robert Ortberg as its new CEO.
