It's McBoeing now

It's technically legal depending on the circumstances, but that's a lot of liability to sign for.

Feel free to check my response below for a detailed answer.

I'm going to start off with saying I am a certificated aircraft mechanic, and I've been exercising my privileges as such for several years on both passenger and cargo aircraft for several airframes.

This situation is actually a VERY big deal and it is going to be VERY expensive and time consuming to fix.

When a part is sold or repaired by a manufacturer, it comes with an airworthiness certificate. In the US, this is FAA form 8130-3. It not only certifies that the part conforms to specifications; but it shows who certified it, who tested it, what specs it meets, and the history of the part. Both the airline purchasing the part and the mechanic installing the part need this document to legally repair the aircraft.

There could be a variety of problems with receiving fake parts that slip by SUP inspections (Suspected Unapproved Parts), and these are both legal and safety problems. A fake serial number means you don't know the true history of the part. It could have been pulled from an abandoned aircraft from a third world country, and even though it passed a bench test, it could be a ticking time bomb. It could be a part in exceedence of service hours, but the paperwork that came with it says it's freshly overhauled.

It could just plain not meet specifications. Premature failure is a big deal. Especially when the list of things that can be broken on a plane (MEL / Missing Equipment List) and still be safe for flight depend on a rated level of reliability. As an example, an aircraft can operate with a certain number of brakes not working for a limited period of time (such as up to two inoperative, no more than one per pair, for no longer than 10 days or 10 flight cycles). This assumes that all of your other brakes aren't going to prematurely, simultaneously fail before that time limit is up.

This article specified that these are engine parts, which adds a whole other level of risk to flight safety. The CFM56 from this article can be rated for ETOPS 180, which stands for Extended Operations up to 180 minutes. Normally, twin-engine aircraft are required to remain with 60 minutes of a suitable airport in the event of an emergency. This often limits what routes certain aircraft can take. ETOPS allows certain aircraft to go farther than the 60-minute rule (in this case, up to 180 minutes), which is a huge deal in terms of flight time, efficiency, and simply whether or not they can fly internationally. To maintain ETOPS rating, the aircraft has to meet stricter specifications. These can range anywhere from parts with tighter tolerances, to things like larger oxygen and fire-extinguishing bottles. They also need to be able to start their APU in flight for a source of electricity in the event they lose an engine.

The airline is also limited on the number of in-flight shutdowns they can have. This number is intentionally very low. If the airline as a whole exceeds this number, their fleet-wide ETOPS rating will be revoked.

Parts have to be specifically rated for ETOPS to be installed on an aircraft flying ETOPS routes. Bad parts make this a huge risk. An in-flight shutdown is a very dangerous situation, and bad parts dramatically increase the risk of that becoming a dual engine failure while that plane spends 3 hrs diverting to the closest airport.

Going forward, there is no good way to check if the parts sold actually meet specs until they're disassembled and checked. Directives from the FAA will be issued. Inspections will be performed. Airplanes will be grounded and rectified. The manufacturer might be able to provide a list of parts that need to be recalled, but more than likely EVERY part they issued will be pulled. They may also have their repair station and manufacturing certificate from GE revoked. Even if they don't lose their certification, most of the airlines will avoid them now.

To address the points you made in your comment, lefixxx, false documents mean bad parts. These parts absolutely DO pose a safety risk. They very likely ARE out of spec, timed out, or simply not rated for what the papers say. Even if the part is tested and meets specs, the history of that part is lost. It will need to be overhauled and made "new" again in order to be airworthy.
All of the regulations and strict document control requirements we follow have all been written in blood. People HAVE died because of things like this in the past, and it's our mission to keep it from ever happening again.

Edit:
Here's an excellent article detailing Partnair Flight 394, and the aftermath wherein they discovered a plethora of counterfeit parts not only on the airplane, but also across the industry at the time: https://admiralcloudberg.medium.com/riven-by-deceit-the-crash-of-partnair-flight-394-f8a752f663f8

I think the issue is more that many people make bad tutorials. They spend way too much time giving irrelevant information when we're only interested in the specific steps for the thing we need. Searching for recipes falls under this category, too.

I don't care what your friend's aunt said about the one time you made this recipe. I just want the ingredients, temperature, and cooking time. Your life story surrounding this pancake recipe can fuck right off.

It can load feeds from multiple accounts and generate a single feed. Very helpful if you subscribe to communities that get defederated from an instance you are on, and you make another account elsewhere to see those communities again.

Easiest example, having your home instance be Lemmy.world with a second account on beehaw. You can browse "all subscribed" for a combined feed.

Sync has ads and subscription fees. Liftoff does not have this.

Sync cannot simultaneously browse multiple accounts. Liftoff can.

The OP's issue can be solved via their lemmy account.

You are commenting in a community discussing the Liftoff app. I understand you are madly in love with the particular app you have chosen; but please consider where you are commenting, and go fanboy in a different community.

My time capsule of cringe will remain closed, thank you very much.

Well, the main salesman for Skydrol (a phosphate based, non-flammable hydraulic fluid for aviation), did not invent the product; but was known to drink some of it during his pitch to "prove" that the fluid was safe. He died of stomach cancer.

I guarantee horse piss has more flavor than Bud Light.

It's easy. Just don't use Twitter.

MW2 (the current release) is a broken, buggy, unfinished mess that has only gotten progressively worse with each update. They did eventually add some very basic features that people had to beg for several months after release. The game is drowning in hackers and toxicity with no end in sight; and runs about as stable as someone taking anti-depressants and anti-psychotics at the same time. It honestly feels like they're rushing to get to their next game as quickly as possible so they can leave this trash heap in the past, while continuing to bleed their current user base dry of as much cash as possible. Their fans are likely hoping that maybe THIS time, Infinity Ward finally learn from the mistakes of the past (but they absolutely won't).

From a basic cash value standpoint, MW2 has been a ripoff. The game started at $70, and immediately they bombard you with in-game ads to buy a $30 pass that's only good for 60 days. Half of the multiplayer content is locked behind this paywall. Each new release of content is $20-30, and they release more DLC packs on roughly a monthly basis while ignoring the core issues ruining the game. With each new update, the style of the game gets closer and closer to looking like Fortnite. If you refuse to buy any of that stuff, you end up with 1/10 of a game that will be decommissioned soon. If you were to go maximum whale mode and buy everything they're pushing to have everything unlocked, you're probably looking at close to $1000.

If you're missing old CoD/Battlefield vibes, just go buy Battlebit Remastered for $15 and have the time of your life. It's been a couple of months since release, and it's still near the top of the Steam charts.

"it's only 5 minutes" is most likely the same inconsiderate thinking that produced that parking job.

About $35-50 at Wal Mart, prepaid, refill when needed. Very easy to get.

Is it for recorded audio or live audio? For recorded, Audacity can remove basic noise profiles. For proper, advanced audio editing, you'll need to use something like the Edison plugin in FL Studio; or a similar process in a DAW of your choice.

The AI options just take all of the work out and make the process easier at the cost of quality and privacy.

Here's Google's translation. Knowing zero Chinese myself, you did very well.

I live very poorly here.
The working environment is unbearable and the benefits are lacking.
But don't worry, only about + people are seriously injured every day,
And I am also very careful. We opened a small shop, and the business is doing well.
Although I don't know English very well, I can understand a little
Understand what those white people are saying.
I hope I can get ahead! I will work hard here, and
Be careful, physically.
How are you?
Miss you very much, hope we can meet again.

Same aisle as the dolphin jelly.

I've had them before. The flavor is a bit different and the texture is a little softer, but it's pretty close. All in all, they taste very good and they're filling like a normal burger; albeit a little expensive compared to meat.

Also, the episodes are an hour long each...
