涉波音,美发布紧急安全公告:尽快改进737 Max飞机发动机

Core Viewpoint - The NTSB has issued an urgent safety recommendation regarding potential engine issues with the Boeing 737 Max, urging improvements to prevent smoke from entering the cockpit or cabin after bird strikes trigger safety mechanisms [1][2]. Group 1: NTSB Announcement - The NTSB's recommendation is based on two bird strike incidents involving Southwest Airlines' Boeing 737 Max aircraft, which are powered by CFM International's Leap-1B engines [1]. - The NTSB highlighted that the engine's safety features could inadvertently release oil into high-temperature components, leading to smoke that could affect pilot performance [1]. Group 2: Company Responses - CFM has expressed full support for the NTSB's recommendations and is collaborating closely with aircraft manufacturers to enhance system performance [2]. - Boeing is also working with CFM on upgrades and supports the NTSB's recommendations [2]. Group 3: Impact on Boeing - The NTSB announcement adds pressure to Boeing, which is already facing challenges following two fatal crashes of the 737 Max that resulted in 346 deaths [4]. - Following the announcement, General Electric's stock fell by 0.3%, while Boeing's stock dropped approximately 1.3% [4]. - A recent crash involving a Boeing 787-8 in India resulted in over 200 fatalities, causing Boeing's stock to decline by 5% on the day of the incident [4]. - At the Paris Air Show, Boeing opted for a low profile amid these challenges, with its CEO canceling attendance, allowing Airbus to dominate the event with nearly $10 billion in new orders [4].
