> The EU is like a tiger - without teeth, fur or claws.
EU regs forced apple to move to type-c. They appear to be moving towards either requiring replaceable batteries, or requiring a higher quality batter (larger % of original charge after 1000 cycles). Those both seem valuable to consumers, and coming from a position of regulatory strength.
Power is defined by the ability to force people to do things they don't want to do - not things that they might have done anyway eventually or that they can feasibly see might benefit them.
In this specific case, the EU gave Apple a golden bridge to retreat over by deprecating the 30-pin cable. If Apple did it themselves, people would have been pissed that they had to buy yet another charger. "Europe is the bad guy, not Apple."
There has been a history of problems with that exact airframe where people died. People dying is usually considered bad.
Now root cause of the issue that airframe had before was that Boeing was given the leeway to certify it themselves with too little oversight by the FAA. In short: the airframe of the Boeing 737 MAX is so far away from the originally certified 737 airframe it is ridiculous to consider them the same airplane. The adjustments Boeing made via softeare to deal with the physical changes (like putting the much bigger engines forward so they have enough clearance under the wings without having to certifying this as a new airframe) was the cause of the incidents. A truly independent FAA would have never even remotely accepted that.
I have read that self-issuance of airworthiness certificates has been normal since the 1950s. Given that, I don't think the issue is due to regulatory corruption but an issue at Boeing which has (hopefully) been resolved.
No it's actually bad when financialization reaches such a degree that planes fall out of the sky.
You as an oncologist: "cells have been dividing for thousands of years and are better off for it. the word is meaningless. I would hate to be a single-celled organism." lmao
Great insight! Therefore there's no such thing as pathological cell division or pathological financialization. Or maybe it's just if someone is super super super smart, they get so smart they somehow lose the ability to distinguish between productive and pathological financialization, and then they get to make asinine comments on HN.
Cancer is a disease that attacks living organisms, similar to how collectivism attacks living societies.
"Financialization" is a 7 syllable word with no definition.
There is nothing about how Boeing builds & sells planes today that is qualitatively different than how they did it 50 years ago. Yes I am familiar with the concern that engineers hold less sway than previously and I agree this is a concern. I would not be shocked to discover that it's true. But this is not a new thing.
People who sell a thing, be they multinational airline manufactures, or a kid selling lemonade, have been able to profit by lying or skimping on quality since the dawn of time.
If your concern is that Boeing will skimp on quality & safety, then say that, instead of a buzz word like "financialization"
I have no idea where you came across the word, but when I see it used, there's generally a lot of handwaving and some vague implication that it's some new concept/activity that started in the 1970's. The only consistencies I've observed in attempts to define it is that money = financialization or "number go up" = financialization, and the speaker is generally uncomfortable with money as one of the tools we use to organize society.
Financialization, in this context, refers to the process by which financial results, especially those legible to capital markets, exert pressure on the upstream industrial/corporate processes and inputs that produce those financial results.
"Excessive" or "obscene" or "pathological" financialization is when that feedback loop or reverse pressure ends up producing negative impacts on industrial/corporate processes, often in pursuit of shorter term positive effects on the financial results.
The exact mechanisms of this have been extremely well-documented in the numerous reports created in the wake of the 737 MAX failures.
Could you try leveling a substantive response now instead of a chain of strawmen and associative "the vibes of the speaker are generally off" type dismissals?
Capital markets have existed for hundreds of years. They are not doing anything today that they were not doing in 1602.
I am familiar with the 737 MAX critique and I'm very comfortable saying that Boeing was sloppy and cut corners. I just don't think the decisions they faced and failed on are new. 300 years ago someone built someone a ship and cheaped out in some way and it sank. Call it cheating/lying/scamming if you like, but the word "financialization" does not help anyone understand what's going on.
No actually there was a pretty specific transition in American business culture to shareholder primacy in the 70s-80s with measurable behavior changes across corporate America, including executive incentive structures.
In 1602 a capital market was where a group of 20 people would pool their money to start a new company to build a ship and go to India and steal some resources and then they would be paid out of those resources in proportion to the money they put in. Is that how they work today?
The problem of "financialization" should also be an old topic by now. It mainly means non-technical bureaucrats (for example, people from finance) taking over the top, making the company focus on maximizing short-term profit and lose its real long-term value.
There is nothing qualitatively different about your cancer cells and your regular cells. That's why it's so hard to treat cancer. Yes I am concerned the genes that modulate cell division are not working as well as previously and I agree this is a concern. I would not be shocked to discover that it's true. But this is not a new thing. Cells that divide have been able to divide since the dawn of time. If your concern is that a cell will excessively divide, then say that, instead of a buzz word like "cancer"
I have no idea where you came across that word, but when I see it used, there's generally a lot of handwaving and some vague implication that it's bad. The only consistencies I've observed in attempts to define it is that cell division = cancer or "uncontrollable replication" = cancer, and the speaker is generally uncomfortable with cellular natural selection as a driving force behind evolution.
Having airworthiness certification done by an independent organization not beholden to Boeing's shareholders makes much more sense to me. Giving the authority to Boeing to do its own airworthiness certification feels like the fox guarding the hen house.
But independents would need to be embedded into the company every step of the way, it would get to be point they would look exactly like Boeing employees.
But what does happen is audits where the work is checked
The 737 has had 14 major recertifications. The aircraft today looks/behaves nothing like the original from the 1960s.
The main motivation for recertifications comes from commercial pressure where if a aircraft is given a new number and not recertified, then the pilots have to be retrained.
Honestly, back when the 737 MAX debacle happened, a lot of consumers claimed that they would stop flying aircrafts if they ran into 737 MAXs. And I don't think it happened in enough numbers - or even enough to make news. Sales went through the roof, everything kept working.
Recertifications are very common. The issue really is is the aircraft is AS different and untested as the old MAXs, and I really can't see that happening again in the next decade or two atleast.
People want to get what they're promised in a reasonable fashion. If the prices are hiding something like nonstandard seats or unreasonable baggage procedures, then that's a legitimate problem, not something they should shut up about because they should have known.
They deserve to know upfront how big the seat is, how big of a bag they can bring, and how much extra bags cost. On top of that, it can be useful if bag sizes and measurement have some standardization across the industry. Nothing major here or hard to provide.
Toyota had the largest recall in history for the unintended acceleration debacle. Yes, lots of people were saying they'd never set foot in a toyota again. Now people don't even remember it.
> Honestly, back when the 737 MAX debacle happened, a lot of consumers claimed that they would stop flying aircrafts if they ran into 737 MAXs. And I don't think it happened in enough numbers - or even enough to make news. Sales went through the roof, everything kept working.
Is this kind of consumer revolt even really possible?
If you feel strongly enough that you refuse to fly altogether, then of course you can avoid flying on a 737 MAX. But I think most people did not feel the risk was that high. They just want to select "guarantee no 737 MAX" when booking a flight, and as far as I can tell that option doesn't exist.
Even if the flight is not a 737 MAX when you book, they can and sometimes do change aircraft, and as far as I know there's no option to get your money back when they do. If you show up and see it's a 737 MAX...you either get on or you lose your money, and have to find some other way to get where you're going, right?
In 2013 there were approximately 24,000 737 flights per day[1] - likely more today. If narrowed to just the MAX variants, it's still thousands per day.
Two, albeit high profile, crashes out of all the daily MAX volume is simply not something to worry about - let alone influence your booking choices.
You're applying everyday casual risk analysis to the highly-regulated environment of commercial air transport, where the MAX crashes absolutely were out of the norm and well beyond accepted levels.
Bear in mind when the crashes occurred there were fewer than 100 MAX in service.
Until you are on the plane. Sorry, but reasonably people and countries expect zero crashes and any single crash is worth worrying about because shareholder money should not trump a single human life.
Honestly they kinda screwed over people -- like me -- who tried to avoid the MAX planes for a while. I'd specifically book around the MAX planes and then they would change equipment at the last minute into a MAX. There is no meaningful "knob" an aviation consumer can turn to express an aircraft preference, and given how US airspace works, you often don't have a meaningful choice in carrier (unless you're willing to take on extra stops).
In the US (parent mentioned US specifically) I think that's just Frontier now that Spirit is gone. I mean technically that's doable sure but idk if I would say trivial it's really limited on routes and the experience is terrible from what I understand.
I have avoided flying on a 737 MAX and have even asked about it at gates when a plane was switched.
Part of the problem though is that many, many, many routes were straight up removed during and after COVID and still haven't returned. There is often no choice, particularly with certain companies like Southwest. However, I haven't flown Southwest since I learned that they were basically complicit, if not directly involved, in Boeing's 737 MAX issues.
This is not exactly the same thing, this isn't Boeing being allowed to sign off on their design -- this is only the airworthiness certificate which means "this particular airplane we just built follows the spec which was already otherwise approved".
Just to comprehend this a bit better - it sounds like the FAA had stripped Boeing of the ability to self-recertify and actually sent inspectors for the most recent certifications. After several successful certifications and what would appear, to the inspectors, to be real process improvements, they're now re-granting Boeing the ability to self-recertify when self-recertification is allowed?
This is well outside my knowledge domain so I'm not trying to make any statements on whether this was correct, but rather to better comprehend the change.
I don't go that far and I'm not exactly scared to fly on a Boeing (because statistically it's still very safe, I ride motorbikes which is probably 100x more dangerous etc etc).
However I definitely prefer flying on an Airbus, put it that way
> The U.S. government on Friday said Boeing
can once again issue airworthiness certificates for its bestselling 737 Max aircraft and 787 Dreamliners, an authority that was stripped from the manufacturer after fatal crashes in 2018 and 2019 of the 737 Max.
I'm a bit confused by this. From what I've read an "airworthiness certificate" is not a certificate that the aircraft design is good and safe. That would be a type certificate.
The airworthiness certificate is issued for a particular aircraft and certifies that it conforms to the approved design for that type of aircraft, all outstanding airworthiness directives applicable to the type have been applied, no unsafe alterations or repairs have been made, all required documentation and logs are present, the inspector doesn't see any damage, leaks, or other problems that could make it unsafe, and other things like that.
The two 737 MAX crashes had nothing to do with anything that would have been found during their airworthiness inspections. They were functioning exactly as they were designed to, as covered by their type certificate.
So what was the point of suspending Boeing's authority to do those inspections?
“You can no longer certify aircraft of this design as safe” seems a reasonable response to a design flaw causing multiple crashes. My question would be whether the design flaws have been addressed. If not, then allowing them to keep making and certifying them does turn the whole exercise into a piece of theatre. Unfortunately, it’s a totally believable decision for some bureaucracies.
The two are unrelated, though. The airworthiness certificate is focused on whether a particular plane is built according to the design. It doesn't say anything about the design. And the planes were still being certified, just by the FAA instead of Boeing.
(Looking at a bit more research, I think this bit was revoked because during the investigation the FAA found that Boeing was skimping on these inspections too, but the details are a little unclear)
> The FAA stopped allowing Boeing to issue airworthiness certificates for 737 MAX airplanes in 2019 during their return to service following the Lion Air and Ethiopian Airlines crashes, and for Boeing 787 airplanes in 2022 because of production quality issues.
The issue was actually the door plug scandal. It showed that Boeing's QC was compromised in their factory and they were not able to properly certify that the aircraft were being built as designed.
As an aside this a long talked-about problem with the South Carolina factory, that the place does not follow aerospace standards and practices. The door plug failure was the highest profile QC miss out of that factory.
I'm just correcting the false statements (probably an honest mistake) in the comment that said "this a long talked-about problem with the South Carolina factory, that the place does not follow aerospace standards and practices. The door plug failure was the highest profile QC miss out of that factory"
It was such a way that you had to disassemble the entire thing to see it wasn't assembled correctly - routine maintenance is looking for wear items, not usually "they didn't put any bolts in".
>So what was the point of suspending Boeing's authority to do those inspections?
Disclaimer: I used to work in airworthiness certification as well as maintenance and design modification engineering for the C-130, but not for any of the Boeing products.
You're generally correct. In layperson's terms, the Type Certificate is like the blueprint or the spec, and the individual airworthiness certificates are a certification that each aircraft coming off the assembly line is in conformance with the approved type design.
When the MCAS debacle happened, the FAA mandated a change to the type design, and further mandated embodiment of that design change through an Airworthiness Directive. This is the part that addressed the MCAS hazard condition. When they withheld Boeing's authority to issue certificates what that really gave them was, at the airframe serial number level, the ability to ensure that the modifications had been embodied correctly.
You're right that that final certification has little to do with correcting the underlying MCAS design flaw on the 737, but there were also quality issues with the 787, and because Boeing's in-house ODA issues those certificates acting as the FAA itself, and those certifications are essentially the last hurdle before delivery of the aircraft (and thus the last hurdle before revenue coming into Boeing's coffers), the FAA withheld that authority so that Boeing employees could not be unduly pressured by management's perverse incentives. Somebody elsewhere in these comments posted the OIG report that briefly touches on this pressure.
In fewer words, it was about ensuring independence in final airworthiness release, and ensuring Boeing's ODA could not be pressured by management who subscribe to the Jack Welch school of ethics.
------
Edited to add:
There is a valid argument to be made that the FAA didn't handle this situation correctly/adequately. For context, in aerospace when we identify that a hazard condition exists we classify both the severity and the likelihood of occurrence. So for example depending on the organization's risk acceptance matrix, one might have a hazard with high severity but extremely low chance of occurrence, and that might be considered acceptably safe (or not!).
The FAA now says that the back-and-forth they have been doing over the last however many months produced comparable production-quality findings regardless of which organization issued the certificates (Boeing's ODA or the FAA itself).
As best I could tell at the time this issue was a hot topic, when it withheld Boeing's issuance authority the FAA never clearly articulated:
- Which risks it was controlling,
- How much risk reduction it expected,
- What data would demonstrate effectiveness, and
- What objective conditions would permit termination of the withholding
So again, there's an argument that the FAA just sort of decided that they now have that Warm Fuzzy and everything is fine.
Recently I was on the tarmac watching people load up on a 737 MAX on an island runway where the takeoff direction was TOWARDS a mountain. I said a prayer.
They should never have allowed aircraft manufacturers to sign their own airworthiness certificates in the first place. Are there that many new aircraft types every year? What is the FAA for? Why does it not take responsibility for certification itself, instead of trusting the aircraft manufacturer’s “Trust Me Bro”?
