No, not at all.
We are relying on what is presented to us in line with the concept of doing a validation. As Mr. Robinson explained, we cannot go back and recertify the entire aircraft. We have to choose the areas we will review.
It so happened that MCAS was not an area that we delved into in any great depth. We were satisfied with the explanation. We raised issues on other matters.
Obviously, the accidents have revealed things about MCAS that we surely wish we had understood, and I believe the FAA would feel the same.
