  据外媒报道,当波音急于推出737MAX机型以抵御来自空客的A320 NEO的竞争时,美国联邦航空管理局(FAA)管理层敦促该机构的安全工程师将安全评估委托给波音,并迅速批准分析结果:波音委托给FAA做的737MAX安全认证,其实是自己部分完成的。

  而波音自己进行安全认证,原因是因为缺乏资金和资源,美国联邦航空管理局多年来授予波音更多的权力,让其承担更多的工作,以证明自己飞机的安全性。

  此外,波音总部所在地的媒体《西雅图时报》揭露,波音公司提交的关于新飞行控制系统的原始安全分析,存在三处致命缺陷,无法证明飞机安全可飞。

波音737max客机的安全认证大多由波音自己完成,这是埃航客机失事的主因?

  具体来看,MCAS系统的作用是:当飞机失速时,通过旋转水平尾翼使得机头向下运动,避免失速。不过,MCAS系统的设计却与波音长期给予飞行员完全控制权的传统相悖。

  然而,接受采访匿名FAA工程师们却指出,在波音的原始安全分析报告中,这项系统存在三处致命缺陷。

  1.报告过低估计了新型飞行控制系统的威力。当飞机投入使用时,该系统使尾翼移动的距离比报告中所称的距离多四倍。

  2.报告无法解释飞行员每次做出操纵反应后系统要如何重置,这意味着报告忽略了系统重复推动机头向下而带来的潜在影响。

  3.报告只将系统故障评估为“危险级”,低于“灾难级”。然而,即使是这一等级也本应该能根据单个传感器的输入阻止系统激活。
