“They were the horrific culmination of a series of faulty technical assumptions by Boeing’s engineers, a lack of transparency on the part of Boeing’s management, and grossly insufficient oversight by the FAA.”
“Boeing failed in its design and development of the MAX, and the FAA failed in its oversight of Boeing and its certification of the aircraft,” the report said, detailing a series of problems in the plane’s design and the FAA’s approval of it.
Une bien étrange façon de résumer un texte détaillé sans aucune concession:
In several critical instances, Boeing withheld crucial information from the FAA, its customers, and 737 MAX pilots. This included concealing the very existence of MCAS from 737 MAX pilots63 and failing to disclose that the AOA Disagree alert was inoperable on the vast majority of the 737 MAX fleet,64 despite having been certified as a standard aircraft feature.65The AOA Disagree alert is intended to notify the crew if the aircraft’s two AOA sensor readingsdisagree, an event that can occur if one sensor is malfunctioning or providing faulty AOA data. Boeing not only concealed this information from both the FAA and pilots, but also continued to deliver MAX aircraft to its customers knowing that the AOA Disagree alert was inoperable on most of these aircraft. Further, Boeing concealed internal test data it had that revealed it took a Boeing test pilot more than 10 seconds to diagnose and respond to uncommanded MCAS activation66 in a flight simulator, a condition the pilot found to be “catastrophic[.]”67 While it was not required to share this information with the FAA or Boeing customers, it is inconceivable and inexcusable that Boeing withheld this information from them. It also argues strongly for a disclosure requirement. Federal guidelines assume pilots will respond to this condition within four seconds.
The Committee found that the FAA’s current oversight structure with respect to Boeing creates inherent conflicts of interest that have jeopardized the safety of the flying public. The Committee’s investigation documented several instances where Boeing Authorized Representatives (ARs)—Boeing employees who are granted special permission to represent the interests of the FAA and to act on the agency’s behalf in validating aircraft systems and designs’ compliance with FAA requirements—failed to disclose important information to the FAA that could have enhanced the safety of the 737 MAX aircraft.69 In some instances, a Boeing AR raised concerns internally in 2016 but did not relay these issues to the FAA, and the concerns failed to result in adequate design changes. Some of the issues that were raised by the AR and not thoroughly investigated or dismissed by his Boeing employees, such as concerns about repetitive MCAS activation and the impact of faulty AOA data on MCAS, were the core contributing factors that led to the Lion Air and Ethiopian Airlines crashes more than two years later.
Boeing’s Influence Over the FAA’s Oversight Structure. Multiple career FAA officials have documented examples where FAA management overruled a determination of the FAA’s own technical experts at the behest of Boeing. In these cases, FAA technical and safety experts determined that certain Boeing design approaches on its transport category aircraft were potentially unsafe and failed to comply with FAA regulations, only to have FAA management overrule them and side with Boeing instead.70 These incidents have had a detrimental impact on the morale of FAA’s technical and subject matter experts that compromises the integrity and independence of the FAA’s oversight abilities and the safety of airline passengers. A recent draft internal FAA “safety culture survey” of employees in the agency’s Aviation Safety Organization (AVS) drew similar conclusions. “Many believe that AVS senior leaders are overly concerned with achieving the business-oriented outcomes of industry stakeholders and are not held accountable for safety-related decisions,” the survey observed.
Cela signifie que le lobbying de Boeing sur la FAA a été suffisant pour laisser passer ces négligences. Ce texte peut permettre l'ouverture d'un procès au pénal contre les individus cités en tête de rapport.
