I'd like to redirect the question a little.
The concern paper that was referred to and discussed at previous committees was not specifically related to MCAS. It was our investigation of the stall characteristics of the airplane to determine the basic dependency of the aircraft on systems, such as MCAS but also other aspects that comprise the stall identification system, to determine whether the aircraft had inherent natural stall characteristics. In other words, does the aircraft require systems to intervene to protect it from stalls? At the end of that exchange, we concluded, thankfully so, that the aircraft does not.
Yes, that issue paper was open, and it was eventually closed with the result we had expected to confirm—that MCAS was not required to maintain a stable aircraft.
