As reported by FlightGlobal the Chairman of the House Transportation and Infrastructure Committee, together with the Chairman of its Aviation Subcommitee, have issued correspondence to the FAA Administrator, pointedly seeking answers to two additionally specified issues concerning the 737 MAX. At the risk of omitting very significant details, the two issues are the inoperability of the AoA Disagree alert, and Boeing efforts to downplay the significance of the MCAS modification of the aircraft.
Though written in typical legal style associated with the Congressional legislative and Committee processes, this SLF/attorney believes the letter is worth the time to read it closely -- specifically because it constitutes a focused effort to implement the provisions of the Aircraft Certification, Safety, and Accountability Act, passed and enacted into law in the prior Congress. As the letter itself notes, the legislation is central to the context here; as it also notes, the letter is direct follow-up to recent testimony by FAA Administrator Dickson (rather pointed follow-up, one might note). As everyone following the 737 MAX saga recognizes, the legislation grew out of the several investigations by various authorities, in which the T&I Committee's work was an immensely heavy factor.
Letter to FAA Administrator (link from Committee website, accessed Nov. 30, 2021) follows. The Committee website also presents a relevant press release.
