from the it's-not-my-fault dept.

[CEO Dennis] Muilenburg said Boeing is making "steady progress" on a fix to the MCAS flight control system that's at the center of crash investigations in Ethiopia and Indonesia, but he stopped short of faulting the software's basic design.

"We've confirmed that it was designed for our standards, certified for our standards and we're confident in that process," he said. "It operated according to those design and certification standards. We haven't seen a technical slip or gap."

Preliminary reports from both crashes suggest that the MCAS system, which is designed to push the Max's nose down under certain flight conditions, was receiving erroneous data from faulty sensors. In both accidents, flight crews struggled unsuccessfully to take control as the airplanes continually dove just after takeoff.

In his remarks, Muilenburg said the incorrect data was a common link in a chain of events that led to both crashes. It's a link Boeing owns and that the software update will fix.

"[The update] will make the aircraft safer going forward," he said. "I'm confident with that change it will be one of the safest airplanes ever to fly."

Without elaborating Muilenburg also said that in some cases pilots did not "completely" follow the procedures that Boeing had outlined to prevent a crash in the case of a MCAS malfunction.

    I guess my point was that Boeing already knows they're boned on this one, they're just pitching limits to their own liability. They will point out that previous pilots encountered this bad sensor and handled it without trouble, but the inexperienced guy did not. They will then say this shows that experienced pilots required no additional training just as they originally claimed.

    I agree, but surely that also implies that fully qualified yet inexperienced 737 pilots do need extra training. I suspect that Mullenburg might regret making that statement.

      That's absolutely the case. I'm not trying to say they're shifting the blame, only that they are working to limit their liability. As a corporation, they would rather lose $2 billion than $10 billion and keep it in the courts as long as possible. It's like saving the bank interesting on billions of dollars. I'm sure they will argue partial liability, going back and forth on how culpable they are, and then argue that they put an adendum in the manual about it and that it's the passenger aircraft companies that didn't review and make note of it. It will go back and forth for years.
