It’s a tool.”The analysis determined that the underlying risks from the MCAS design were unacceptably high without at least some FAA action, that they exceeded internal FAA safety standards and that the likelihood of another emergency or even accident “was over our threshold,” according to the FAA official. “We decided…it was not an acceptable situation,” the official said.
So the FAA decided this after the October accident... and then waited for three days after the second accident before grounding the plane. Something sure doesn't add up here yet
