美国FAA对停放在疫区的2000架波音737飞机发出紧急指令

周五，美国联邦航空管理局（FAA）对2000架在美国注册的波音737 NG和Classic飞机发出紧急适航指令，并警告停放的飞机可能出现的腐蚀现象会导致双引擎故障。FAA表示，如果航空公司发现腐蚀，他们必须在飞机再次飞行之前更换阀门。波音公司(BA.N)上周五表示，已建议运营商检查飞机，并补充说："由于COVID-19大流行期间对飞行需求的降低，飞机一直停放在机场，使用频率不高，所以阀门会更容易被腐蚀。"

Administration (FAA) on Friday issued an emergency airworthiness directive for 2,000 U.S.-registered Boeing 737 NG and Classic aircraft, warning of possible corrosion on parked planes that could lead to a dual-engine failure.If airlines find corrosion, they must replace the valve prior to flying the aircraft again, the FAA said. Boeing Co (BA.N) said on Friday it had advised operators to inspect the planes and added “with airplanes being stored or used infrequently due to lower demand during the COVID-19 pandemic, the valve can be more susceptible to corrosion.''  source
