美国联邦航空管理局（FAA）本周发布最终检查指令，要求对波音737 Max机型进行强制裂纹检查[1]。该指令涵盖737-8、737-9和737-8200三个型号，涉及约471架飞机[1]，并将于9月10日生效[1]。
FAA做出此决定是基于早前在旧款737飞机上发现的裂纹报告[1]，认为Max机型由于设计和制造工艺相似而面临相同风险[1]。检查将重点关注飞机的前向承力带[1]。FAA表示该问题可能"不利影响飞机的结构完整性"[1]。
波音公司早在2019年已向运营商发送过相关检查指令，FAA随后在2021年对其进行了强制执行[1]。
The U.S. Federal Aviation Administration has issued a final directive requiring inspections of approximately 471 Boeing 737 Max aircraft for structural cracks, effective September 10, 2024 [1]. The mandate applies to three variants of the aircraft—the 737-8, 737-9, and 737-8200 models—and focuses on the forward load-bearing strap component [1]. According to the FAA, the potential issue could "adversely affect the structural integrity of the airplane" [1].
The inspection order stems from crack reports previously discovered on older Boeing 737 aircraft models [1]. The FAA determined that the 737 Max variants face the same risk due to similarities in design and manufacturing processes [1]. Boeing had already sent inspection directives to operators in 2019, and the FAA enforced the requirement through regulatory action in 2021 [1].
