Mr. Robinson and Mr. Turnbull, welcome back to the committee. I realize that you've had certainly a lot of work over the last two years. I was very glad to hear that there are no outstanding concern papers left on the MAX 8.
However, in the past, there were outstanding concern papers, in particular with respect to the MCAS. Can the witnesses describe for the committee what changes were made to the MCAS while the plane was grounded that led to the MCAS concern paper being resolved?
