"Bernhard" continues to provide top-notch coverage of the 737 MAX debacle, having been ahead of the curve from day one.

It's not just bad, it's very bad. They've screwed the pooch on this one, and a software tweak isn't going to cut it. At minimum, the whole fleet is going to need a hardware rework. This design should never have made it past the drawing board. (And apparently, they had to lie to the regulators to do it. That won't go down well.)

Cue handwringing about regulatory capture, institutional rot, etc. (And cue justified kvetching about the monkey wrench thrown into budget transatlantic travel... e.g. )

Cockpit voice recorder of doomed Lion Air jet depicts pilots' frantic search for fix

The pilots of a doomed Lion Air Boeing 737 MAX scoured a handbook as they struggled to understand why the jet was lurching downwards, but ran out of time before it hit the water, three people with knowledge of the cockpit voice recorder contents said.

Investigators examining the Indonesian crash are considering how a computer ordered the plane to dive in response to data from a faulty sensor and whether the pilots had enough training to respond appropriately to the emergency, among other factors.

The captain asked the first officer to check the quick reference handbook, which contains checklists for abnormal events, the first source said.

For the next nine minutes, the jet warned pilots it was in a stall and pushed the nose down in response, the report showed. A stall is when the airflow over a plane's wings is too weak to generate lift and keep it flying.

The captain fought to climb, but the computer, still incorrectly sensing a stall, continued to push the nose down using the plane's trim system. Normally, trim adjusts an aircraft's control surfaces to ensure it flies straight and level.

The manufacturer has said there is a documented procedure to handle the situation. A different crew on the same plane the evening before encountered the same problem but solved it after running through three checklists, according to the November report.

But they did not pass on all of the information about the problems they encountered to the next crew, the report said.

Amazing how badly Boeing is handling this--like they can stick handle the public the way they did the FAA.
"Everything's okay now folks--you can get back on our planes." I don't think so.

Company is likely facing lawsuits not only from families of the deceased, but from carriers with grounded planes, which they may never be able to use again if customers won't set foot on 737 MAX.

Despite explosive decompression problems to start with, it was manufactured for twenty years, until 1988, and ended passenger service in 2014 (major airlines in 2007). As long as the FAA and the carriers are putting the planes into service, most people won't know or care about what type of plane they're taking.

>3 2wonderY: Yep. And they found the horizontal stabilizer jackscrew at the crash site in Ethiopia in the full nose-down position. (Actually, the whole playlist here is worth reviewing, although it's inconveniently in reverse chronological order: )

Meanwhile, Lion Air demonstrates why it is not allowed to fly in the EU:

Bottom line: Having suffered damage to a non-redundant (!) safety-critical system, the planes needed to be jury-rigged to counteract their "default" behavior of forcing nose-down every 10 seconds, the cumulative effect overriding any ability to counteract it by yoke inputs. (Yes, that kind of a nightmare.) Luck of the draw whether any given flight crew had the requisite knowledge to bypass the systems in the middle of a double-whammy emergency. (Much blame does go to the poor documentation from Boeing). Unfortunately, after successfully doing so, Lion Air crews handed the live grenade off to their peers.

Not a nice flavor to the story ~

Doomed Jets Lacked 2 Key Safety Features That Boeing Sold as Extras

For Boeing and other aircraft manufacturers, the practice of charging to upgrade a standard plane can be lucrative. Top airlines around the world must pay handsomely to have the jets they order fitted with customized add-ons.

Sometimes these optional features involve aesthetics or comfort, like premium seating, fancy lighting or extra bathrooms. But other features involve communication, navigation or safety systems, and are more fundamental to the plane’s operations.

Many airlines, especially low-cost carriers like Indonesia’s Lion Air, have opted not to buy them — and regulators don’t require them.

Now, in the wake of the two deadly crashes involving the same jet model, Boeing will make one of those safety features standard as part of a fix to get the planes in the air again.

Boeing’s optional safety features, in part, could have helped the pilots detect any erroneous readings. One of the optional upgrades, the angle of attack indicator, displays the readings of the two sensors. The other, called a disagree light, is activated if those sensors are at odds with one another.

Boeing will soon update the MCAS software, and will also make the disagree light standard on all new 737 Max planes, according to a person familiar with the changes, who spoke on condition of anonymity because they have not been made public. The angle of attack indicator will remain an option that airlines can buy.

Neither feature was mandated by the Federal Aviation Administration. All 737 Max jets have been grounded.

“They’re critical, and cost almost nothing for the airlines to install,” said Bjorn Fehrm, an analyst at the aviation consultancy Leeham. “Boeing charges for them because it can. But they’re vital for safety.”

“There are so many things that should not be optional, and many airlines want the cheapest airplane you can get,” said Mark H. Goodrich, an aviation lawyer and former engineering test pilot. “And Boeing is able to say, ‘Hey, it was available.’”

But what Boeing doesn’t say, he added, is that it has become “a great profit center” for the manufacturer.

Hundreds of in-house complaints about the problem were reported before the crashes. The public of course had no access to them. (Which 737? Check the two crashes in Colorado; I don't need to as it not important to my point, which is that the public is not allowed to know the history of a certain plane and that when a problematic plane is identified they certainly do become concerned about them. If over a number of flights there are no more problem, in time the public will indeed forget.)

The emerging 737 MAX scandal, explained
It’s more than bad software.
Matthew | Mar 29, 2019

...The story begins nine years ago when Boeing was faced with a major threat to its bottom line, spurring the airline to rush a series of kludges through the certification process — with an under-resourced Federal Aviation Administration (FAA) seemingly all too eager to help an American company threatened by a foreign competitor, rather than to ask tough questions about the project.

The specifics of what happened in the regulatory system are still emerging (and despite executives’ assurances we don’t even really know what happened on the flights yet). But the big picture is coming into view: A major employer faced a major financial threat, and short-term politics and greed won out over the integrity of the regulatory system. It’s a scandal.

The 737 versus 320 rivalry, explained

There are lots of different passenger airplanes on the market, but just two very similar narrow-body planes dominate domestic (or intra-European) travel. One is the European company Airbus’s 320 family, with models called A318, A319, A320, or A321 depending on how long the plane is. These four variants, by design, have identical flight decks so pilots can be trained to fly them interchangeably.

The 320 family competes with a group of planes that Boeing calls the 737 — there’s a 737-600, a 737-700, a 737-800, and a 737-900 — with higher numbers indicating larger planes. Some of them are also extended-range models that have an ER appended to the name and, as you would probably guess, they have longer ranges.

Importantly, even though there are many different flavors of 737, they are all in some sense the same plane, just as all the different 320 family planes are the same plane. Southwest Airlines, for example, simplifies its overall operations by exclusively flying different 737 variants.

Both the 737 and the 320 come in lots of different flavors, so airlines have plenty of options in terms of what kind of aircraft should fly exactly which route. But because there are only two players in this market, and because their offerings are so fundamentally similar, the competition for this slice of the plane market is both intense and weirdly limited. If one company were to gain a clear technical advantage over the other, it would be a minor catastrophe for the losing company.

And that’s what Boeing thought it was facing....

...on March 27, FAA officials faced the Senate Commerce Committee’s Subcommittee on Aviation and Space at a hearing called by subcommittee Chair Ted Cruz (R-TX). Cruz says he expects to call a second hearing featuring Boeing executives, as well as pilots and other industry players. Cruz was a leader on the anti-Boeing side of the Export-Import Bank fight years ago, so perhaps is more comfortable than others in Congress to take this on.

When the political system does begin to engage on the issue, however, it’s unlikely to stop with just one congressional subcommittee. Billions of dollars are at stake for Boeing, the airlines who fly 737s, and the workers who build the planes. And since a central element of this story is the credibility of the FAA’s own process — both in the eyes of the American people and also in the eyes of foreign regulatory agencies — it almost certainly isn’t going to get sorted out without more involvement from the actual decision-makers in the US government.


Above was about Air Bus / Boeing rivalry, but Boeing also sought tariff relief from Canada's Bombardier, which was denied by the US International Trade Commission (Jan 2018):
"The ITC commissioners voted 4-0 that Bombardier’s prices did not harm Boeing and discarded a U.S. Commerce Department recommendation to slap a near 300 percent duty on sales of the company’s 110-to-130-seat CSeries jets for five years."

Trump administration sides with Boeing in Bombardier dispute
Alana Wise | December 20, 2017

The U.S. Commerce Department announcement to impose (steep anti-subsidy duties on Bombardier Inc’s CSeries jets) of nearly 300 percent stems from a complaint by Boeing Co that Bombardier had been unfairly and illegally subsidized by the Canadian government, allowing the planemaker to dump its newest jetliner in the U.S. market below cost...

>16 prosfilaes: Well, I'm not surprised, as youth craves perceived victory more than knowledge. Now, the point begins with the fact that a car generally sticks to the ground, so a crash mid-travel is less likely to kill than a plane crash. Planes, and their tight regulation and seatbelts and all, when they crash, usually kill everybody in them. We happen to know of many situations when airlines kept information about dangerous planes from the public. In fact, it is routine. If we knew the flight records of every plane we flew in, we would be scared shitless to fly. Rather than educate people about planes so that transparency does not disturb flyers, airlines simply hide facts, and though we will likely never know how many crashes were thus unnecessary, too many have been. There is the point.
The trite bullshit about flying being the safest form of transport is tangential to this point, as is the fact that nearly a-US-soldier-in-Vietnam's worth are killed on highways every year. Corporate greed and dishonesty are responsible for an unacceptable and absurd fact--that flight records are not public information--that people like you are apparently gulled into not thinking this through, and that more people than necessary are killed in crashes.

Ralph Nader Calls For Recall Of Boeing 737 Max Jets After His Grandniece Was Killed (4:29, Transcript)
April 4, 2019


Today, the family of one of the Americans who died on the Ethiopian flight filed a lawsuit against Boeing and took steps to file another suit against the FAA. Samya Stumo was 24 and was traveling in Africa for a job in global health. She was the grandniece of consumer advocate Ralph Nader. He spoke to us today.

RALPH NADER: Audie, it's a tragedy beyond words because Samya Stumo was only 24. And she had leadership and compassion and intellectual rigor. So it's a loss to her family and relatives. But it's a loss all the people working in global health and all the people she would have helped save over the next 50 years. So we have to make airline travel much safer.

CORNISH: The lawsuit filed today accuses Boeing of rushing the 737 Max 8 plane to market. Your niece, Nadia Milleron, Samya's mother, spoke at the press conference today. Here's what she said.


NADIA MILLERON: As somebody who's lost a dearest person in my life, you know, I want her death not to be in vain. I don't want anybody else to die.

CORNISH: What, to your mind, is going to take for your family to feel like enough is being done to prevent another crash?

NADER: Well, the 737 Max 8 was defectively designed. It put in larger engines which destabilized the aerodynamics of the plane. And that's why Boeing went to such lengths with all the different iterations of the complex software. It's because in rushing to compete with the Airbus 320neo, they put on larger engines for a little more fuel efficiency. And they upset the center of gravity and made the plane prone to stall, rather than stall-proof...

...I'm calling for a recall, not just continued grounding, a recall like the auto companies of the 737 Max 8. They've got to go back to the drawing board, a clean sheet design of a new plane. And in the meantime, they can continue selling their Boeing 737 800s without those larger destabilizing engines...

Boeing announced Tuesday that deliveries for all of its 737 jets fell to 89 in the first quarter, a dip from 132 last year.

The plane maker halted deliveries of its 737 Max following the global grounding of the jets that were implicated in two fatal crashes in Ethiopia and Indonesia that killed a total of 346 people.

maig 11, 2019, 1:51pm

Oh brother. Just keeps getting worse.

In the middle of Boeing 737 cockpits, sitting between the pilot seats, are two toggle switches that can immediately shut off power to the systems that control the angle of the plane’s horizontal tail.

Those switches are critical in the event a malfunction causes movements that the pilots don’t want. And Boeing sees the toggles as a vital backstop to a new safety system on the 737 MAX – the Maneuvering Characteristics Augmentation System (MCAS) – which is suspected of repeatedly moving the horizontal tails on the Lion Air and Ethiopian Airlines flights that crashed and killed a total of 346 people.

But as Boeing was transitioning from its 737 NG model to the 737 MAX, the company altered the labeling and the purpose of those two switches. The functionality of the switches became more restrictive on the MAX than on previous models, closing out an option that could conceivably have helped the pilots in the Ethiopian Airlines flight regain control.

Boeing declined to detail the specific functionality of the two switches. But after obtaining and reviewing flight manual documents, The Seattle Times found that the left switch on the 737 NG model is capable of deactivating the buttons on the yoke that pilots regularly press with their thumb to control the horizontal stabilizer. The right switch on the 737 NG was labeled “AUTO PILOT” and is capable of deactivating just the automated controls of the stabilizer.

On the newer 737 MAX, according to documents reviewed by The Times, those two switches were changed to perform the same function – flipping either one of them would turn off all electric controls of the stabilizer. That means there is no longer an option to turn off automated functions – such as MCAS – without also turning off the thumb buttons the pilots would normally use to control the stabilizer.

Peter Lemme, a former Boeing flight-controls engineer who has been closely scrutinizing the MAX design and first raised questions about the switches on his blog, said he doesn’t understand why Boeing abandoned the old setup. He said if the company had maintained the switch design from the 737 NG, Boeing could have instructed pilots after the Lion Air crash last year to simply flip the “AUTO PILOT” switch to deactivate MCAS and continue flying with the normal trim buttons on the control wheel. He said that would have saved the Ethiopian Airlines plane and the 157 people on board.

“There’s no doubt in my mind that they would have been fine,” Lemme said.

Boeing said in a statement that the company had historically called for pilots to flip both switches to shut of a problematic or “runaway” stabilizer, so the change on the MAX ensured that the function of the switches matched that procedure. The company said the two switches “were retained for commonality of the crew interface.”

“Boeing strongly disagrees with any speculation or suggestion that pilots should deviate from these long-established and trained safety procedures,” Boeing said.

And cf.

jul. 16, 2019, 9:15am

In which the WSJ catches up with "b". Worth noting, also, that the latest problems found with the trim wheels also affect the 737 NX (vintage 1997), of which over 7,000 still fly every day. Simply a matter of luck that they've never caused an issue thus far.

Bottom line:
The 737 MAX delays puts Boeing under extreme pressure. This can be seen in the alarming tone in which its major lobbyist, Loren Thompson, argues for the company:
737 MAX isn’t just one of the jetliners in Boeing’s commercial product mix, it is the pivotal offering of the entire enterprise. Over 80% of the company’s order backlog is commercial airplanes, and four out of five of those commercial planes are 737s. The company’s latest 20-year forecast of demand for jetliners projects that 74% of the 44,000 commercial transports ordered worldwide over the next 20 years will be single-aisle aircraft, and 737 is the only single-aisle jetliner Boeing makes.

What is largely missing from coverage of the MAX crisis, though, is an explanation of how important Boeing’s sole single-aisle offering is to the company’s fortunes, to the nation’s trade balance, and to the fate of local economies in the U.S. Boeing manufactures all of its products in the U.S., so if it were to falter, the economic fallout would be extensive.
Thompson calls on 'lawmakers' to 'emphasize constructive solutions' for Boeing's situation.

A constructive solution would be to fix the current airplane and to also create a new one. But that is likely not what Thompson has in mind. Congress pressure on the FAA and large subsidies for Boeing is what he is really aiming at. Congress should refrain from either.

That Boeing shareholders demanded larger profits was a main reason why the company created a 737 MAX kludge from the already old 737 NG. It should have build a clean sheet airplane as it originally planned to do. The shareholders made a lot of money when Boeing spent some $48 billion on share buy backs. It is only just that they now bleed to fix the issues their greed originally caused.
