“Whereas the certification flights are an essential milestone, various key duties stay,” the FAA mentioned in a press release. “The FAA is following a deliberate course of and can take the time it must totally evaluate Boeing’s work. We are going to elevate the grounding order solely after we’re glad that the plane meets certification requirements.”
