Gremlins... Not good for Boeing obviously. They really really didn't need this.

Are the regulators going to strongly react?

No. This is just a quick inspection to make sure a component in the electrical system is properly grounded. It doesn’t affect all MAXes and it shouldn’t take long for the affected Airlines to perform these inspections to determine if more work is required on this component or not.

Yup and appears to be a specific group of aircraft. My guess is an audit uncovered somebody checked off on something they should not. And now Boeing needs to verify the work completed.

Not a huge crazy thing but it's still ridiculous the amount of issues Boeing has in QC in the production their aircraft as of late, so incredibly disappointing to see the mess that is Boeing currently. Especially since this thing sat on the ground for 2 years and still didn't catch it.

I’m not sure it is entirely a quality control problem. If you search for issues on an airplane, you’ll find them. On any airplane. Even the best maintained.

ADs come out all the time for all planes. ADs still come out for like Saab 340s and B1900s

Practically how long does it take to check it and repair it if required? Can it be done right away or does it require something bigger or Boeing's own mechanics?

https://twitter.com/reutersaero/status/ ... 81157?s=21

It says 90 planes in total

Takes hours to fix or a few days.

It doesn’t seem that big of an issue. But it’s MAX so everybody gets their knickers in a twist

Obviously this is the worst publicity immediately after grounding for Boeing ever imaginable....



And the timeline for the fix sounds rather fuzzy. Hours or days is a big difference!

Boeing says it is “premature” to estimate how long repairs to the jets might take, but adds that the maintenance work could take “a matter of hours or days”.

As opposed to weeks, months, or years? This is not a big deal. Move on.

From the FR24 newsletter

"Southwest has said 30 of its MAX are affected by the recommendation, but it expects minimal disruption to its flights."

Here is the website if you want to entertain yourself with how many issues like this are addressed on an ongoing basis. 109 in the last 60 days alone.

https://www.faa.gov/regulations_policie ... irectives/

American has 17 affected aircraft.

https://twitter.com/juliejohnsson/statu ... 80801?s=21

Came from a production change.

Isn't the title wrong? The problem isn't that some of the planes will be grounded. It's that some of the planes might be ungrounded.
Or, I guess it's accurate if "Ground some of the jets" refers to tightening the ground screw.

To airlines that is a big deal. Money spent on fixing a jet is money lost when the jet has to be sitting around.

I can assure you for AA, there is not fleet slack for the MAX. Sure 1 or 2 aircraft for a few hours but not 19 spare aircraft worth. AA has already cancelled 25 flights today due to those aircraft being out of service.

So much for these airplanes being thoroughly inspected for any other issues before being returned to service.

I mean, it being the MAX probably adds to that problem. Regulators are being very very careful. Especially the FAA. No airline has experienced this problem before. It happened during normal manufacturing operations. Also once you fix it you can reintroduce it into service. Of course doom and gloom is what some of you love to see

A lot. I'd say that most aircraft models have had one at one point in the lifetime.

You can easily tell who has an aviation background by the comments in this thread. Stuff like this happens all the time, its a non-issue. If we talked about every AD issued there would be multiple threads per day, as that's about how often the FAA publishes them.

Lot of people in this thread who have never looked at the AD database before. Might surprise you.

They are getting paint primer in a bolt hole. Not the end of the world. It’s not a design flaw.

It was discovered and will be corrected. That’s the safety process working.

mcdu wrote:

Probably any one pertaining to the MAX -- for a while going forward anyway.

I have heard the issue is with the "backup power control unit." Apparently there are questions regarding whether it was installed with proper grounding (electrical) integrity in airplanes delivered since the original grounding (operational) was lifted. Does anyone know exactly what a backup power control unit is?

Not a major issue itself but another glitch with Boeing’s processes and controls.
What’s the next one?

Paint in an bolt hole is not that big problem. Two times with an thread cutter, and you can go on build your project car.
But it is always a sign for, that things are done more hurried and less care is taken.

It's not the end of the world, but it was enough to require a grounding. That ain't great for a plane that's had its issues and on which they've had abundant time to get stuff right.

Sounds to me like this falls under the "stuff happens" rather than the "OMG!" bucket, and we'd never hear about this under normal circumstances.

It’s not a fleet grounding. People are getting the “grounding” term mixed up. It’s a possible electrical grounding issue.

They're not flying the relevant planes until it's fixed, right? So that's a lot of non-usable planes, even if some of the fleet doesn't have the current mess-up.

Perhaps it's a grounding due to grounding, but...

Although this may be a small issue, its not.. After all the scrutiny this aircraft has been under for the 20 months it was grounded there literally should be NOTHING wrong with it. Seriously, if this was overlooked, what else was? Boeing has embarrassed themselves more than enough as of late and quality control needs a hard-core overhaul.

Whilst not the entire fleet, seems serious enough that Boeing has said that the inspection is needed prior to further operations. So effectively a “grounding” for the affected tail numbers.

There have been 109 ADs in the last 2 months including other manufacturers who haven't had the sordid MAX screw up happen to them.

This is what a QA/QC program does. Catch problems BEFORE they become incidents. There will be many more ADs on the 737 MAX just the same way there will be on the 787, a350, a320, 777X and <insert model here>

And then you fix it and return it to service. The fix is very well known according to sources and will be shared with operators. Take it out for 2 days fix it and put it back. I mean you people need to move on

Bear in mind no operator has experienced the problem Boeing is talking about. Please

+1 exactly what I thought when I read that. Actually laughed outloud. Second place goes to the earlier post that “this is literally the worst thing that could happen to the MAX after being ungrounded.” LOL

And these are the same people that cried “a huge percent of travelers will refuse to fly the Max.” Airlines are already considering taking down all the MAX exceptions, waivers and related content because there’s been virtually NO noticeable impact. Of course those posters are silent on that now.

If something actually serious happens it will be bad. But until then I don’t understand why the constant doom and gloom posts with nothing productive to say don’t get deleted.

Ah, so Boeing is finally beginning to do its job and ensure that its planes are safe without governments having to do the job for them. Great. Fantastic. Pardon me if I don't feel particularly impressed by that.

This too, though. If they keep the things in the air and in one piece, they'll be fine.

To be honest the media also doesn’t help but they won’t because they don’t know details. Sec Butigieg was asked if he still trusts the FAAs decision to unground the jet. Like seriously?

This Boeing being proactive and just telling operators. Just take it out and fix it and put it back. Wow a lot of you just do not like Boeing and that is completely understandable but just say you don’t instead of doing armchair stuff

You mean the same media that kept calling MCAS an “anti-stall” system? It’s not. Not even close to being accurate.

People like drama and sensationalism - just like a few people on this thread. The media doesn’t help. They seem too lazy to do even the simplest of fact checks these days.

In fact, I believe the electrical grounding only affects a backup electrical system. Even if an airplane did unknowingly fly in that condition it’s not a real safety issue unless there were other unrelated failures.

Correct me, if this is wrong.

Of course it still needs to be fixed to ensure proper safety margin.

It doesn’t warrant responses like, “OMG, I’m going to avoid that airplane.....”
