Aviation

[gtb1943]

They MD-11 is very old. Passenger airlines retired them years ago. Some aircraft have service limits and some don't.

sounds like the FAA needs to tighten things up there
We know because of the B52 and the DC3 you can keep planes flying for a very long time; but also you need to virtually rebuild them to do so.

At the very least, the older a plane gets the tougher the maintenance standards should be.

Generally, these things are caused by a multitude of failures from the manufacturer, FAA, the operator, and individuals involved. That's why I was saying don't be quick to throw blame around. If I had to guess, I would say the FAA probably allowed too much time between inspections, the inspections weren't comprehensive enough, or the work wasn't done properly, due to a number of reasons. It is probably a little bit of everything. Most of the FAA regulations are written in blood, meaning it takes an accident to find flaws in systems.

With all of that said, it is amazing how safe aviation is, when you are looking at the sheer number of people being flown around the world at any given time. It's truly a miracle.

just when one crashes it gets lots of pub

if there was a crack in a main component, it might not show up in regular maintenance procedures, right?

I honestly don't know. It could have been hidden from plain sight and inspected at a longer interval. The NTSB will get to the bottom of it. They are really good at what they do.

Someone educate me on this. If it was just the pylon that failed, what caused the #3 engine to fail? I thought it was debris from the #1 engine.

I don't think they have determined if it had completely failed or not. It could have ingested debris, or the hot air from the fireball could have caused a compressor stall. You can see in picture 3 that the fireball/debris went right over the engine.

Kind of didn't matter exactly what happened to #3 really
I guess one could say something significant broke
watching something like this is so eerie.

If the engine just came off cleanly, they could have climbed out on 2 engines, but yeah, you're right. We have no idea how badly the slats, wing, and other surfaces were damaged yet. The NTSB will figure it out.

I guess we are fortunate that there are so few videos of events like this. Watching people die is almost like watching a snuff film
you feel like you should not watch

From looking at the videos, it looked like the #3 engine was having a compressor stall. But apparently it was the #2 engine, the one on the back. Does pic #6 look like some flame is coming out of it?

I don't know. We're both looking at the same thing. None of it is normal. The NTSB will sort it all out.

[gtb1943]

well no surprise there

sounds like there was no way to visually catch this; so it will come down to whether there should have been a mandated replacement of those components after either so many years or so many flight hours or takeoffs/landings.

I wonder if they can figure out how long it was weakening?

With an aircraft this old, sounds to me like they (FAA) were remiss in requiring more care. Requiring replacement of critical components on a strict schedule.

Wow. Never got more than 30 feet off the ground. Amazed at how much damage these large jetliners can do with a full tank. This, 9/11, etc...

 

[Flamma]

So they grounded these types. But what about this failure makes it specific to these types only?

This plane was in for maintenance in San Antonio for 6 weeks. What were they doing?

until the NTSB releases the maintenance logs, we will not know. But from what the recent NTSB release said, a visual inspection would not have detected the metal fatigue that caused the crash.

Dallas–Fort Worth was built to be big, but it was the pandemic that proved how flexible the hub really is. Now the airport and American are pushing that advantage with a roughly $9 billion capital program: a new Terminal F, phased rebuilds of Terminals C and A, rebuilt roadways, airfield upgrades, and a modern utility backbone. It’s all aimed at pushing DFW from today’s high-80-million passenger counts toward 100 million by the end of the decade, while making the place faster for banks of American flights and simpler for drivers. Funding comes from airport revenues, airline rates and charges, PFCs, and the 2023–25 use and lease deals—not local taxes. And it’s happening in a metro whose GDP rivals whole countries. This video shows what’s changing and why it matters. We’ll look at the history, the new terminals, the roadway fixes, and how DFW plans to handle future growth at scale.

Beautiful looking plane.
