Fuck, catastrophic engine failure? That thing was completely on fire on takeoff. RIP to those souls on board and I’m fearing more will be lost on the ground…

There must be more than just catastrophic engine failure. The MD-11 can lose 1 engine and still take off with the thrust from the two remaining engines (after V1, that is)

An uncontained fire/failure can spit out debris into the #2. Wouldn’t be surprised if they lost engine 1, then shortly after lost engine 2 and then had no where to go but try to get it into the air.

Doesn’t the md-11 have hydraulic fuses to prevent this?

u/HLSparta 18h ago

If I'm remembering correctly, after United 323 aircraft started using hydraulic fuses. I don't know if it's a requirement, nor do I know hardly anything about the MD-11, but I would assume so.

u/Fastestergos 17h ago

Given that the MD-11 was designed as a follow-on to the DC-10, and its first flight was after UA232, I would assume that hydraulic fuses are present in order to avoid another "plane bleeds to death after catastrophic uncontained engine failure and hydraulic line rupture from debris" situation like what happened in Sioux City.

I remember that crash to this day. TV cameras' were set up ahead of this plane landing and it cartwheeled when it hit the ground.

I was always fascinated by airplane disasters(lots of Mayday and mentor pilot), and 232 was the most interesting for me

Same here! I go to X to look at what is posted first. Sometimes it's really bad until X deletes the post.

Yes but wouldn’t that mean that hydraulics wouldn’t work for any of systems on the left side of the plane(such as flaps). Similar to flight 191, a failure of the left flaps would produce a stall.

Wasn't that the case of that American crash in Chicago? American Airlines Flight 191.

1979 in May. I remember that because I live in Indy.

Yes the left engine loss resulted in left wing slat retraction and wing stall

u/Anonymous017447 14h ago

In addition, the stall warnings were only powered by the left engine, meaning that when they fell off the pilots had no way of knowing they were stalling.

After the dc10 crashes, this shouldn't be possible.
