The extended grounding of some Boeing 737 Max jetliners is adding to pressure on Boeing and the subcontractor that made the fuselage and installed a panel that blew out leaving a gaping hole in an Alaska Airlines plane last week.
Investigators know the sequence of events that led to the blowout Friday night, but they don’t know the cause. A key question is whether bolts used to help secure the panel, called a door plug, were installed. A National Transportation Safety Board investigator says the bolts have not been recovered and the agency won’t know if they were even in place until the door plug is examined in a laboratory.
Adding to Boeing’s problems, Alaska Airlines and United Airlines — the two U.S. carriers that fly the Max 9 — reported finding loose bolts and other hardware in other panels, suggesting quality issues with the door plugs are not limited to one plane.
The plugs are installed in Max 9 fuselages by subcontractor Spirit AeroSystems, which was spun off by Boeing in 2005. Spirit has a history of manufacturing problems, many uncovered in a U.S. House probe of two fatal crashes involving Boeing 737 Max 8 planes.
“The focus needs to turn to Spirit,” said former congressman Peter DeFazio, who chaired the investigating committee. “Boeing has been happy with the crappy stuff from Spirit because it’s cheap.”
The company said in a statement Monday that “quality and product integrity” are a priority. “Spirit is a committed partner with Boeing on the 737 program, and we continue to work together with them on this matter,” it said.

The process of inspecting Max 9s and returning them to service has been slower than Alaska and United had hoped. The Federal Aviation Administration grounded all Max 9s in the United States on Saturday until they could be inspected, but Boeing didn’t provide inspection instructions until Monday.
On Tuesday, the FAA said those instructions were being revised “because of feedback,” and it extended the grounding of the planes.
“The safety of the flying public, not speed, will determine the timeline for returning the Boeing 737-9 Max to service,” the FAA said in a statement.
However, the inspection delays threw airline schedules into turmoil.

United said it canceled another 170 flights Tuesday because of the grounding. Alaska said it scrubbed 109 flights because it couldn’t fly Max 9s.
The part that failed on the Alaska flight is installed on some Boeing jets when airliners don’t have enough seats to require more emergency exits. The plugs are lighter than an aircraft door, reducing the plane’s weight and saving fuel. They are common on cargo planes that have been converted from passenger use.
During a briefing late Monday, NTSB officials described how the plug on Alaska flight 1282 rolled upward and flew off the jet. Four bolts and 12 connecting points between the plug and the door frame are supposed to prevent that from happening.
“We have not yet recovered the four bolts that restrain (the plug) from its vertical movement, and we have not yet determined if they existed there,” said NTSB aerospace engineer Clint Crookshanks. “That will be determined when we take the plug to our lab in Washington, D.C.”

It is not clear whether Spirit AeroSystems or Boeing technicians last worked on the door plug, which can be opened for maintenance. Steven Wallace, former head of accident investigations for the FAA, said it was unlikely that Alaska crews worked on the plug because the plane was only delivered to the airline in October.
That means the investigation will likely focus on manufacturing, assembly and quality control, Wallace said.
This could put more pressure on Boeing CEO David Calhoun, who was brought in to help the company get past the crisis created by the Max crashes. During his tenure, Boeing has lost $23 billion and struggled with manufacturing flaws that have at times held up deliveries of 737s and larger Boeing 787s.
Calhoun called an all-employees meeting Tuesday, hosted at the company’s 737 factory in Renton, Washington.

“We’re going to approach this, number one, acknowledging our mistake,” Calhoun said, according to comments provided by Boeing. Reporters were not allowed to attend. The CEO said he trusts the NTSB to find the cause of the accident, and trusts the FAA to take all necessary steps “to ensure every next airplane that moves into the sky is in fact safe, and that this event can never happen again.”
No one was seriously hurt Friday aboard the affected Alaska jetliner, but Ed Pierson, a former senior manager at Boeing’s 737 factory, said the door plug issue is a wake-up call for Boeing and regulators to act before something worse happens.
Pierson, now the executive director of The Foundation for Aviation Safety, said Boeing assembly line workers are pressured to rush, and that the company has cut back on quality control inspections. That, he said, can lead to mistakes.
“The pressure is ‘Move the plane down the line,’ It’s not, ‘Stop, let’s fix it, let’s do it right,’” he said.

Other former Boeing employees and outsiders who have examined the company say its safety culture degraded after a 1997 merger that left many McDonnell Douglas leaders in charge.
“They rejected the Boeing culture, where the engineers had the final say on everything, in order to chase the stock price and their executive options,” DeFazio said. “They need to go back to being what they were and could be, which is the greatest engineering aerospace company in the world.”
Spirit AeroSystems’ record is also likely to come under more scrutiny.
In a federal securities lawsuit filed last May in Manhattan, an investor charged that Spirit concealed widespread quality failures including defects in fuselage fittings, improperly drilled holes in bulkheads that keep planes pressurized, and missing fasteners.

The lawsuit includes an unidentified manufacturing team leader’s email that said a manager told workers to falsify reports on the number of defects found on planes. The lawsuit was reported early Tuesday by The Lever, an investigative-journalism website. Spirit declined Tuesday to comment on the lawsuit.
Sen. Richard Blumenthal, D-Conn., said the NTSB must determine “whether additional inspection and maintenance should have been done before the aircraft carried passengers anywhere.” He asked new FAA Administrator Michael Whitaker what the regulatory agency is doing to protect air traveler safety.
A focus on how the door plugs were installed could be the best outcome for Boeing, said John Goglia, a former member of the NTSB. He said a finding of sloppy installation work would eliminate the need for more costly, time consuming door plug redesign.
“Installation errors happen all the time,” said Goglia, who started his career as an aircraft mechanic. Faulting the installation in Boeing planes “impeaches their quality system, but it doesn’t impeach their design.”

Shares of The Boeing Co. fell 1% Tuesday, a day after they plunged 8%. Spirit AeroSystems was nearly unchanged Tuesday but lost 11% Monday.

I visited the Boeing assembly plant at Everett near Seattle in 1988 when they were starting assembly of the 747-400. At that time Boeing was an engineering focussed company with Engineers in charge. You could feel their pride in quality just by walking around the place.
Unfortunately I suspect the company is not like that anymore as it appears that it was taken over by accountants and "manager" types after the merger with McDonald Douglas in the 90's and later with more outsourcing etc.
I hope they can get back to focussing on engineering type management and quality rather than profits. Just my 20 cents worth of observations.

I may have misheard, been mistaken, or been mislead... I worked for Hughes Aircraft Company starting in 1981. I was lead to believe our DoD contracts were "Cost plus 5%" deals. My first program was just preparing the first prototype for Navy/DoD acceptance and the engineering changes, and hence cost were fast and furious. It was engineering driven and I was lucky to work with and for some incredible people. That program to support the F/A 18 Radar (another Hughes product) was alot of fun, back in the day (and a ton of long days, late nights on salary). With the demise of Howard Hughes, the company passed into a charitable trust benefitting a hospital in Florida IIRC. Some lawsuit or other forced the trust to divest itself of Hughes Aircraft Company and I found myself working for GM subsidiary Hughes Aircraft Company. When MBAs look to maxiise profits (that is what an "Masters of Business Administration" does) corporate culture of excellence sometimes becomes a corporate culture of economies....
I transferred to the TR1/U2 Radar program after field assignments with the F/A18 at NAS Lemoore , CV43 Aircraft Carrier Coral Sea and a Canadian Forces Base in Cold Lake Alberta. The TR1 progam was (probably still is) a very low volume radar program. We had only 10-15 flying birds and a total of 19 or so Radar Systems, each lovingly handbuilt...

Don't know for sure, but it certainly looks like one.
 
AP News: “The jet involved in Friday’s blowout is brand-new, having been put in service in November. After a cabin-pressurization system warning light came on during three flights, the airline stopped flying it over the Pacific to Hawaii.” emphasis added
Wait, WTF?

Greater depth:
https://mailchi.mp/5c6edb7c2062/tfs...ax-bright-side-sneaky-dog-412008?e=9ec2545e58

Thought; If loose bolts is the problem, that's a company/worker issue that's nearly terrifying, and if it can't be narrowed down to issues with a single "work group" mindbogglingly far ranging in scope.
FAA; we think you need to look at all assemblies that have come out of SpiritAS since, oh 2010?? A company that was near bankruptcy just a couple months ago.

Perhaps an inevitable result in a company where "management" turns into "dictatorship".

It's a sad fact that as lot of enterprises once led by engineers thinking 'safety' now seem to be led by accountants thinking 'profits'. Same this side of the Atlantic. For example, safety losing out to cost savings in the National Health Service.

In general manufacturing, it's less safety than plain old quality and all over we can see how quality has been sacrificed for cheapness. We benefit and lose out, living in a culture where money has become the main or perhaps only yardstick.

A cabin pressure warning (or caution) light has nothing to do with hull integrity. Zilch. How could it know (in advance) that a part of the pressure vessel is going to fail? It can't... it's not clairvoyant.
The cabin pressure light comes on when the pressurization system senses a fault. It could be that there's a disagree between what altitude is selected and what's actually being seen... could be one of the PAC's (Pressurization and Conditioning System) has an electronic fault, a sensor leak.... it could be any number of things. What it isn't is an indication that a door plug is getting ready to let go. It can't know that any more that you can know you're going to be in an accident on your morning commute to work.... that's crystal ball territory.

I seldom knock the press these days, as that seams all the rage... but in this case, the press is making too much of something they don't fully understand.
 
The cabin pressure light comes on when the pressurization system senses a fault
Like an air leak from a loose "hatch plug"?
:twocents: Sounds like something that needed more investigation. especially since the ships flight mission profile was altered because of that fault indication.
Captain: We have a pressure fault light! Maint; aw, they ALL do that....
Accidents are usually the result of more than one failure in the safety "chain".
 
Like an air leak from a loose "hatch plug"?
Couple things...
First, if you've never sat next to a leaky door or window, you don't know what you're missin'. Makes the most gawdawful squeal you can imagine. That would result in "numerous" pax complaints for the 3 flts or so the light was reported on.... including this one where the plug failed. Since I assume the worlds press corp has prolly contacted most of the people on that plane looking for a scoop, a loud squeal would be the headlines right now. It's not. It was likely sealing just fine right up to the point of failure.

Second, all pressurized aircraft "leak" by design. The pressurization pumps run wide open... non-stop the entire time the plane is pressurized. Pressurization "control" is by way of an "outflow valve." Just like the name implies, it regulates the amount of air leaving the plane. Pressure too high? The outflow valve opens further. Pressure too low, it closes down to allow it to rise..... a regulated leak.

Pressure sensors measure the amount of pressure and can even measure the rate of increase or decrease over time. What they can't do is tell you where the leak's at.
 
Makes the most gawdawful squeal you can imagine.
Pilot friend of mine started his airline flying in Embraers, which carried the unfortunate nickname Skoda of the Skies - highly unfair on both. He said the planes tended to have leaky doors and, Yup, they made a horrible squeal and Yup, this worried passengers. Part of the cabin crew's job was re-assuring pax that this was quite normal and nothing to worry about.

Told him once that the big lever-handle doodah on the doors - planes in general, I've never been on a Embraer - labelled with an arrow and OPEN always worried me a bit. What if in some moment of madness or whatever, a passenger waiting outside the loos pulled that lever?

He re-assured me that even if that happened, it would be impossible to open the door because the pressure in the plane holds the door firmly SHUT, that's why plane doors have to open inwards. Doh!

Yep. Max differential pressure on most modern aircraft is 8 to 9psi So lets assume a door is 3ft by 6 ft. That's a little over 2000 square inches.
Evan at 1psi differential, it would take 2000 lbs of force to displace the door. 'Taint happenin' unless you're Superman.
 
I have not read Through ..but some short comments .. I have been working in companies going bust
Which Boeing can be spiraling down into.

As we speak Customers are asking questions the airlines don't want to Hear
" What make of airplane are you selling tickets for "
Impossible to lie and then there are customers at present time that turn around at the counter and goes somewhere else
Or stay at home
That airline is risking to fly with discounted prices and half empty planes. Worst case not flying at all.
And are going to ask Questions that Boeing don't want to hear.

So the greedy cost cutting is mostly an effect of that the product and Service is not Competitive.
Once that happens ..customers are starting to go elsewhere.
The talented staff ones after sitting in the wages negotiation with the Human Resources
Hearing him say " Sorry we cannot pay that ..the company has Problems "

leaving the room thinking hell no --not my fault : He is already gone starting to ask around.
The real talents can have offers or friends that put in a word so he can be gone within a month or two
And are getting that salary the company in Problem cannot pay A brain drain so to speak
That is how a market works
Quality cost money be it Parts or Staff.
The poor profitability does also affect the spirit in the company ..

To sum it up once the company is having problems of the type that can be suspected here.
I have rarely seen anyone being able to do a Turnaround.
I takes massive firings and shaking up which can destroy the informal ways of work

I know of one turnaround one lady firing 90 % of the the management team that did work.
 
I hope they can get back to focussing on engineering type management and quality rather than profits. Just my 20 cents worth of observations.
Yup. Some years back, I worked for "the phone company" (rhymes with "horizon"). It was all about doing the best job you could, and providing the best service for the customers. Always the customer first. It was about the spirit of service.
Then, after a couple name changes, the bean-counters took over, and the company atmosphere started a down-hill slide. Fortunately, I was able to retire before all the bolts came loose.
 
Corporate America problem, when you think of your standings \portfolio, stockholders are more important than the people making your product
they will notice.
When enough of them get the gist of it all the cheap labor you can find won't fix it.
And for this kind of work neither will the most expensive machine you can buy.
And just for the f of it, time's running out There's just not enough people out there geared to this kind of work.

In many ways that sounds like the place I worked from 1968 up to 2015. Every time there was a merger or such things got less personal . With every merger there was just another layer of management people. In other words more people who do nothing directly related to getting product out the front gate. Each and everyone of them making more a year than those producing the product that earns the company money. So little by little various benefits were cut back to help pay them until there was very little left.

Before me my dad worked at the same place starting in early 1950's. Almost up to the time I retired in 2015 I can't remember them putting a "Help Wanted" ad in the paper or any place. Now for at least the last 2-3 years they have had a large banner tied to the fence begging for people to apply for a job.

Sure a job in stone quarry might not be a high prestige job but in the 60 years I had connections with the place many people managed to keep a roof over their heads and food on their table. Some didn't but most those had other problems, mostly self inflicted from a bottle or such.

A stone quarry job may not have prestige to an idiot, but it does to me. I told my kids, and now my grandkids to NEVER look down on any man or woman doing an honest days work. My favorite saying is that the garbage man that comes by my house on Wednesday's is far more important than some guy playing a child's game or playing make believe on TV or in a movie.
