Nevertheless, the FAA mentioned that additional investigation precipitated the company and Boeing to resolve two months in the past “that the failure price of each switches is far increased than initially estimated, and due to this fact does pose a security subject.”
The FAA mentioned it does not know why the switches failed. Boeing mentioned it’s working with the FAA and the swap provider to repair the issue.
