I-5 wrote:Yeah, we still don't know why that off-duty pilot on the other flight was able to save them. It's equally troubling that the on duty pilots on the previous flight had the same problem and couldn't solve it.
Having said that, there is no way to know if the knowledgeable pilot could have saved the Ethiopian Air flight, unless he knew something that even Boeing didn't know, since the Ethiopian pilots followed their training they were given according to the report.
I-5 wrote:It’s not as simple as throwing switches; if you read the link I posted, the former Boeing engineer talks about the extreme forces that a 40 degree dive (which was documented on the Ethiopian flight) and the extreme airspeed (in excess of 500 kts) would have put on the stabilizer could make it physically impossible to counter it. We don’t know that the Lion Air flight that survived got into a dive that extreme.
I-5 wrote:You're right, that with airplane crashes, it's never one thing; it's always a string of events that lead to a crash. For example, the Aeroflot flight that crashed because one of the pilots let his kid sit in the captain's chair, had the crew not tried to counter the turn that the kid made while they weren't looking until it was too late, the plane would have righted itself in autopilot mode, and all the other things they did that actually made it worse.
To Muillenberg's credit, he mentioned these factors that they own and will remove so that they will never be a factor again:
1) the fact Boeing decided MCAS only needed data from 1 sensor instead of 2, even though every plane already has 2
2) the software decision to not let MCAS reset after an input from the pilot, so that MCAS wouldn't automatically kick back in (it was kicking back in every time, making the dives steeper and faster)
3) the decision by Boeing to offer a disagree warning light as an option instead of as standard
The last one is ridiculous...imagine offering a car with seat belts as an option. That's why capitalism needs regulations.
I-5 wrote:Yep. Just one disagreement: the pilots didn’t increase their airspeed voluntarily; MCAS did by virtue of the repeated node down attitude it kept activating.
I-5 wrote:The flight only last 6 minutes, everything they did was to get the nose up, which requires throttle. We’ll see when more comes out. In 70% of accidents it is pilot error, but I don’t see evidence of that here. They literally tried to follow every Boeing directive.
One of the weaknesses of our capitalistic system is that there are times that the most responsible individuals in a company, the executives and Board of Directors, are the last ones that are held accountable, or not held accountable at all.
I-5 wrote:Riv, in both cases of Wells Fargo and NASA, logic says mid level managers and engineers don't have much incentive to do things that are improper without pressure coming from higher up.
I think Boeing has two dangers; execs trying to please shareholders by rushing planes to market, and two, poorly trained (from multiple accounts) workers, at least in the 787 plant and possibly other plants where debris and shoddy work has been discovered after they had been supposedly inspected.
From what I've read, the FAA suffers from lack of budgets and manpower, so it's not exactly the same type of capitalistic greed, but probably a by product of it.
I-5 wrote:If I was an engineer whose lives depended on my work, it would be a nightmare to think that I would also be the person to certify it. I would want the oversight from a third party who isn't under pressure to approve it. Unfortunately, this is not the current state as you pointed out. Probably the only people that don't mind it are, again, Boeing execs. I know there is a movement already to separate the roles of CEO and president at Boeing, since they are both occupied by the same person. Despite saying that, I doubt that heads will roll at Boeing or the FAA. I hope I'm wrong.
From my experience working in a creative agency, micro managing comes in the form of not just WHAT to do, but HOW to do it (their way of course)
I-5 wrote:I'm sure you all read that during inspections, the FAA found an additional flaw within the 737 Max.
From Boeing's website:
"CHICAGO, June 26, 2019 – The safety of our airplanes is Boeing’s highest priority. During the FAA’s review of the 737 MAX software update and recent simulator sessions, the Federal Aviation Administration (FAA) identified an additional requirement that it has asked the company to address through the software changes that the company has been developing for the past eight months. The FAA review and process for returning the 737 MAX to passenger service are designed to result in a thorough and comprehensive assessment. Boeing agrees with the FAA's decision and request, and is working on the required software. Addressing this condition will reduce pilot workload by accounting for a potential source of uncommanded stabilizer motion. Boeing will not offer the 737 MAX for certification by the FAA until we have satisfied all requirements for certification of the MAX and its safe return to service."

The good thing is that FAA looks like it's trying to establish itself again in its proper role. On the other hand, could Boeing do any worse than right now? I know some of us (myself included) originally thought we'd go on board a 737 Max, but I abandoned that idea a few months ago, and this news just guarantees it. I'm now a little more concerned about the other 737 models that might share similar components or software.
I-5 wrote:It's been a while since this OP, but I think I might be ready to say the 737 Max as currently designed from a hardware standpoint will never fly again. I just doubt that a software fix is all that's needed to right a very seriously flawed approach that made sense only to businessmen, not to aeronautical engineers (namely, using an old airframe for newer bigger engines to save on certification time). Not telling the airlines specifically about the MCAS to also save money on flight sim time also made it worse. And now this from CNN today:
"Congress also heard last week from a Boeing whistleblower who worked on the 737 Max and had urged managers to shut down the production line because of mistakes and cut corners. He said his recommendations fell on deaf ears. An FAA analysis dated December 2018 — weeks after the first crash — predicted there would be more than 15 additional fatal crashes of the Max over its lifetime. That document was made public at a House Transportation Committee hearing on Wednesday."
The Boeing we know and love is not today's Boeing in my book. That Boeing died when they decided to move the company HQ to Chicago, and that is when the problems with the 787 and 737 Max programs began.
I-5 wrote:You might be right about the merger, Riv, though it could be argued that Airbus provides plenty of global competition. I tend to think it's the business-first approach by the suits in Chicago, instead of the actual airplane guys that Seattle Boeing was known for. But yeah, both factors could contribute.
I-5 wrote:I’m a bit surprised you’d tease someone about a dam accident that killed people, but maybe i dont understand the context properly. As for the FAA, I agree heads should roll there, too, but the reality is Boeing has owned that agency, and more than a few politicians, for such a long time. Boeing is in the biggest existensial crisis in its history, and i think 2020 will be a defining year for the company.
