That would require more evidence than it sounds like there is. And that's assuming that you subscribe to the motivations put forward in this article. I generally follow Hanlon's razor - "Never ascribe to malice that which can adequately be explained by incompetence". I have a hard time believing that a cover-up in Boeing was orchestrated over several years by a group of people all who didn't care about loss of life.…

The Volskwagen saga can also be attributed to incomptenence but alas! it was not caused by it but by malice.

We are humans after all and money talks.

The razor is for non-economical causes.

I generally follow: never ascribe a reason until you have sufficient evidence to support it, Be it malice or incompetence...

Manufacturers take the blame for this. And they take the blame for things like no global transponder in the loss of the 777 over the Atlantic. Unfortunately the FAA processes, while enlightened in some ways, and firmly grounded in the science of safety, are effectively a strong deterrent for a manufacturer to avoid changing anything in a design.

The result is that many aircraft operate for a very long time with very outdated systems. Replacing designs is prohibitively expensive to prove to the FAA that there will be no corresponding degradation of the system's performance or new safety risk. Unfortunately such a process does not calculate the cost of not replacing the system. No cost is attributed with keeping something that is old and lacking in capability.

The result is that aircraft systems are woefully behind what technology can offer. And this is not just the hardware or the software, it includes the procedures and the overall set of capabilities. The result is that aircraft are being operated to the standards of the 50s, when in fact a much higher standard of crew and aircraft performance is possible. When I say performance I am also talking about safety performance, the ability to operate without harm causing failure.

I worked under a CEO who had worked at Boeing before, and he said before that at times there was a number that a life was worth when making decisions while he worked there, in a conversation about diminishing returns in quality. Now I’m not sure if he meant that literally and there’s a number in the Boeing employee handbook, but he had a point. He said they could make planes cost twice as much and save a few lives th…

The NHTSA has a similar number, I believe its in the realm of $2 million per life. Its based off of medical costs and a few other "organic" numbers to estimate what the population as a whole values a life at. Its morbid but it has to be this way or transportation would be unaffordable.

That's not what happened in this case. They used a single piston where commonly two or more pistons would be used to control the rudder.

Earlier quoted context omitted.

Sounds like something a CEO would say to cover up for shitty management and cost cutting R&D.

He was a a great CEO, and invested in R&D greatly for a startup that self funded, and more importantly for me, a good person and someone I still consider a friend. Kind of rude if you to jump at the throat like that.

I'm sorry I came in hot. I even misread the original comment. These recent events with Boeing have got me bothered I apologize for my rudeness.

Was that the final resolution then; that Boeing were ordered to replace the part, and the crashes stopped happening? Was there ever a formal investigation into whether Boeing knew the true cause of the rudder hardover, and chose to ignore it and blame other stuff?

From the post: "The NTSB report recommended that the valve be redesigned, and the Federal Aviation Administration mandated that the changes be implemented by November 2002. Since then, no 737s have crashed due to rudder hardover or rudder reversal."

Unsurprisingly, the aviation insurance industry has also cost per life calculations. An aviation insurance broker who bought industry data from us wanted to know if there was any way we could provide them with hard data or reliable estimates the percentage of passengers flown by an airline flights who were American citizens, because the potential liabilities associated with the loss of American lives were so much greater...

Agreed. The implications of the story make a good movie script, but it's hard for me to imagine how this could play out practically across so many people and so many years. I mean whole careers started and ended in this saga. I was thinking a more likely explanation is that once the original issue that ultimately was found to be the cause was dismissed, and after more and more fatalities built up, the consequence of…

These are companies driven by greed. If they're in any way culpable, they should suffer consequences. There's nothing else to it.
