Failure of maneuvering system caused Boeing crash of Ethiopian airlines
Almaty. April 5. KazTAG - Boeing CEO Dennis Muilenburg said the Boeing crash of Ethiopian Airlines was caused by failure in the Maneuvering Characteristics Augmentation System.
"The full details of what happened in the two accidents will be issued by the government authorities in the final reports, but, with the release of the preliminary report of the Ethiopian Airlines Flight 302 accident investigation, it's apparent that in both flights the Maneuvering Characteristics Augmentation System, known as MCAS, activated in response to erroneous angle of attack information," he said.
In his words, the history of industry shows most accidents are caused by a chain of events. "This again is the case here, and we know we can break one of those chain links in these two accidents. As pilots have told us, erroneous activation of the MCAS function can add to what is already a high workload environment. It's our responsibility to eliminate this risk. We own it and we know how to do it," he said.
"From the days immediately following the Lion Air accident, we've had teams of our top engineers and technical experts working tirelessly in collaboration with the Federal Aviation Administration and our customers to finalize and implement a software update that will ensure accidents like that of Lion Air Flight 610 and Ethiopian Airlines Flight 302 never happen again," he added.
In his words, the company is taking comprehensive, disciplined approach to get the software update right. "We're nearing completion and anticipate its certification and implementation on the 737 MAX fleet worldwide in the weeks ahead. We regret the impact the grounding has had on our airline customers and their passengers," he added.
This update, along with the associated training and additional educational materials that pilots want in the wake of these accidents, will eliminate the possibility of unintended MCAS activation and prevent an MCAS-related accident from ever happening again.
