Boeing Discovers Faulty Fastener Installation On Undelivered 787 Dreamliners

Boeing is investigating incorrectly installed fasteners on its undelivered 787 Dreamliners. More than 900 fasteners were reportedly affected per plane. The FAA Administrator plans to address the quality lapse during a visit to Boeing's facilities in South Carolina. Boeing has launched an investigation into a quality problem with its undelivered 787 Dreamliners. Reports suggest that hundreds of fasteners have been incorrectly installed, but there is no immediate safety risk. ( More...

Incorrectly torqued fasteners are a rookie mistake that should have been caught during inspections. We used to have to witness the Torque being applied. Maybe the inspectors had poor training?

Or the torque wrenches were out of calibration

No..they said thewy torqued by the head and not the nut. You always hold the bolt head and torque the nut.

There are 3 components to fastener torque. First is the elastic stretch of the fastener that clamps the parts together (known as Preload), which has to be within certain range determined by the applied load on the fastener. This is the most important part of torque.

Second is the ‘running torque’ required to rotate the nut. That is changed by any lubrication of the threads. Some aerospace fasteners come with a dry lubricant already applied, so the fastener specification is important in this regard - use the correct spec fastener. If the bolt is being torqued, there is also the closeness of the fit in the hole to consider.

Third is the torque required to overcome the friction between the nut/bolt head on the mating surface of the part.

The final torque value is the sum of the three parts. Always desirable to torque the nut if possible as there is less of parts 2 & 3 to account for. Using the specified nut torque on the bolt head instead will result in an under torque situation, which may or may not be within the specified range of torque. As mentioned the work card process spec should be adhered to.

I know all too well about fastener torque and the calculations engineers must do to achieve the torque required.

Learned, decades ago, that proper torque is asserted via the nut not the head. The Nut torque is critical as it assesses the amount of stretch the threads will have to apply proper clamp force on the joint.

That said we also learned the differences in bolt torquing vs bolt (hydraulic) tensioning. The later can more precise, but it is a mastered art and only used in certain circumstances. Where as torque required can be obtained via a torque device. It is also critical to make sure such device is properly calibrated and calibration maintained. When doing a torque to yield application, (this is seen in areas where it states to torque to a certain amount of ft/lbs (or Nm) and then apply an additional degree rotation) it is also critical to make sure the degree gauge used is in proper calibration.

Either way, the bolts mentioned were improperly torqued. My only hope is Boeing knew enough to discard all fasteners of the area and apply new before going through the torque sequence again. This is done because all bolts would have had the thread stretch measurement skewed and all bolts should have been tightened in a sequence.

maybe the process spec has then TQ`ing the head. everything is in the process spec for every part including fasteners, QA job is to make sure it is Tq to that spec. unless QA was not around to verify. In ST Louis QA verifies everything including the hole final size before the fastener is installed. At least it was that way 20 years ago.
A rookie mistake? No. A rookie wide receiver running the wrong route is a rookie mistake. Using the term "rookie" to describe a new employee "supposedly" trained to assist in the manufacturing of a passenger aircraft is unsettling. Boing "has launched an investigation"...really...again? Boeing should be shut down until they get their damn act together. That includes hiring people that are capable of doing their job. If you cannot comprehend the training to correctly torque a fastener, then maybe being a cashier would be a better career choice. I am sure if we go back to hiring those capable of doing a job rather than those who are incapable but "deserve a chance" things will get better.

So sad. I always revered Boeing as a paragon of USA aviation excellence and prowess. Praying they come to their senses and start using the original engineer and technician driven processes.

Will you knock it off with your Boeing/DEI garbage!
It began when the bean counters, who had up and left Washington state and made head office in Chicago, took over engineering duty! Profit Profit Profit

Are you blind or just like skirting an issue??
Let's haul off and place blame other places when it's the head office idiots who call the shots. "Make us money we don't care how" Which is why they are in the mess they are in. Boeing issues started lomg ago but it seems both you and Overdue put blinders on and point the blame solely at others, namely DEI candidates
How about finding who or what found the improperly installed part and telling the (media) inspections are working.. then correcting the fault? Oh well, telling the facts is not newsworthy, just scaring people.. is NEWS.

Are you a race baiter? No, I don't have a problem with women. Do you? I do have a problem with "anyone" who is hired "becuase" of race and gender, and not aptitude and intelligence! And so should you! Wise up!

Here..let me fix your "foot in the mouth" comment: "I do have a problem with "anyone" who is hired "becuase" of race and gender, and not aptitude and intelligence"

For some reason I think it should have stated: "I do have a problem with "anyone" who is hired without the proper aptitude, paperwork and intelligence, to do the job properly!" You have a very "strange" fixation on DEI, and NOT the issue at hand!

Bill was Overdue to embarrass himself again

Of course for years white males were hired based on race and gender and that was ok with you. What are you afraid of? BTW, if you look at the major screwups lately at UA and WN, it’s all white males.

I have no credibility in aviation matters, but I have owned and managed businesses many years. Boeing came to SC because of government incentives and a right to work state with anti union policy. I hear the comments about management, and profits, but I begin to think what is really at play. Management can't overcome a poisoned culture with the front line workers. Companies don't make money. They do things right, and profits are a result. Managers often ignor this. Who created and sustains this turmoil? Who most stands to gain? Management, shareholders, governments, or unions. I don't know, but whenever I hear all the finger pointing, I fall back to follow the money.

Not only should they move corporate back Seattle, but they should also move 787 production back to Everett.

The usual overpriced management trying to save a few pennies by trying to go cheap, but instead end up costing the company billions with problems like this.

The sad thing is that before someone becomes a whistleblower, they usually go through reporting channels to get things fixed. In a lot of company cultures, that can be a career ending decision, especially if cost or schedule is impacted.

The fastener installation problem is unreal. People who are putting together an aircraft should know more about how to torque fasteners than high school shop students. How can they get that far without it being detected?

If they don't get the basics under control, the company will go under.
Dan Nelson 4
Ulimitly, the customers will define quality for Boeing.
Dave Mathes 4 a long since A&P, I guess the thing that really bothers me are the people installing this they not know or just not care about the shoddy work they turn can't just be management...

Is ANYONE running the show at Boeing?
francrimi 2
For the purpose of public safety, we need articles like this to keep coming out and keeping everyone informed. The best way to get a publicly traded company to straighten out is to expose them. Boards of Directors of these types of companies are all heavily invested shareholders.
Robin White 2
Not sure how, given what they know and don't know, they can say with any believability that existing a/c are not affected by this "lapse". Really?
fred wyse 4
When I was a kid the saying was: 'You only get what you pay for.' Boeing moved to the South to satisfy Wall Street. The saying is still true: You only get what you pay for. That learning curve long ago reached its mean result. This is the best it will ever get for Boeing.

Can you imagine the courage it took to climb into the Boeing Starliner?
djames225 1
Can u imagine the cursing being done, under breath of course, by those 2 astronauts as they are still at the ISS.

Or they could be be happy as they were just to test and not become long haul ISS crew.
Poor training and qualified people may be involved about rules and quality practices in security and reporting.

"The incorrectly installed fasteners were torqued from the head instead of the nut."

A trained and skilled sheet metal mechanic knows how to correctly do this job. Obviously the hired mechanics do not! So perhaps dei did play a role? I cannot believe of all the mechanics doing this job not a one knew it was wrong? And to speak up? A well trained union mechanic would have known. Obviously none of these employees knew their job and had proper training perhaps due to a language barrier?

The fact that HEADS have not ROLLED shows that Boeing cares neither for its one-time standards nor its customers, nor its end-users (us).

For instance: Despite ALL, the CEO is allowed to hang around until 12-31-2024. He should be copying his resume at Kinkos! WHAT is the Board THINKING (if at all)?

Cavalier regard for safety in transportation should be actionable. Boeing is hundreds of miles off course, and evidently not responding to radio queries. It is UNCONSCIONABLE.

I'll say it again, Boeing will be bankrupt in 5 years!

At this rate it may be less. Look up Comac. Boeing gave their tech to Comac in a deal in 2011. FAA finally put sanctions on the company in 2021 - banning US companies from doing biz with them. Too late - horses out of the barn.

And your professional and acedemic credentials leading to your expertise about the financial condition at Boeing ?

Agreed, I'm aware of Comac, and it's part of my rationale!

I doubt it, Bill. Taxpayers, you and I (and the US DoD) will be bailing them out.
Peter McDevitt 2
I’ve had thoughts about this, Boeing may have reached a point where they will have to find a ‘white knight’. The number of firms that could fill that role have to be very limited. I’m thinking maybe Lockheed? I do remember when they built great airliners

Yup. Too big to fail.

Yup. Too big to fail. lol

America needs Boeing to succeed like we needed GM to succeed ...a lot of ignorant people objected to that 'bailout"

You should refresh your memory on "bailouts " Most of that went to General Motors, which paid back about $39 billion of the $49.5 billion invested.

We are getting ready for war over Taiwan....over what ?


Yup We cant do without oil chips or planes

You sure you're not an Overdue relative? You both have this fixation on 1 thing without thinking it through! That and you love blaming others for mistakes that should be addressed at the top!

BTW..DEI can equal QRP but you two can't seem to wrap your heads around that! Boeing itself, in its higher ups, failed the later. The ways things look, they decided to skip over quality to get the P.R. Seems whistleblowers and employees agree on that as well.

I agree with you, Howard! Let Boeing buy some cleaning machines to get rid of numerous useless managers and CEO's. Give the company back to the original engineers and technicians who made Boeing great in the old days. Start again at scratch!!!

Ever since the deceptive crooks from McDonnell Douglas took over, Boeing has gone down the crapper. I avoid flights on newer Boeing aircraft made after the takeover. As long as these greedy crooks are in charge, Boeing will continue being a substandard company making unsafe planes with the cheapest parts from China.
turn out the light the party is 0ver Boeing

...Arthur, does this have anything remotely to do with the Boeing issue in discussion?..
Stephen Rogers 4
I think so. Quality needs to be built in, not inspected in. The workers and supervisors need to all work together to make a quality product.

Other countries are doing better at controlling quality than we are. Demming found that out when he was rejected by Detroit and accepted in other parts of the world.

Our attitude here has become you don't pay me enough to do quality work. Pride in workmanship has gone way downhill.
Nooge -1
Another old white man who thinks America is not Great anymore
That's not what I think at all.

I'm not sure what age and race have to do with it.

I do see a bad attitude that is causing quality problems.

The quality of my work is not dependent on my pay. I always do the best I can and take pride in what I do.

A lot of people today seem to be proud of the fact that the quality of their work is tied to their perception of fair pay.
Nooge -2
Demming never wrote about people who believe that only they always do their best and take pride in what they do.

They say things The workers and supervisors need to all work together to make a quality product and their attitude and character is no longer prevalent in the workforce today

I do know is that cars last way longer than they did

Not sure what age and race have to do with ?

Its usually old white men who have issues with Detroit
