If regulatory capture isn't part of the Congressional investigation, then it has no credibility, and we can assume that there is Congressional capture as well. The NTSB does have a history of criticizing the FAA, manufacturers, and pilots, with regard to the facts. Therefore I'm reasonably confident they will indicate inadequacies in the regulatory regime for such a misfeature/misdesign to have escaped into the wild.
