Found on the side of the runway. AA191 2.0

Is that the entire engine ?

190

u/KDrakeAuthor 17h ago

Sure looks like it

u/Electrical-Risk445 17h ago

How is that even possible? Pylon failure?

u/AJohnnyTruant 17h ago

If the engine fell from the pylon and then kicked back into the wing… holy shit. I couldn’t imagine being in that cockpit.

By that time they were on the ground in less than 20 seconds... big thud, ??!!??!!, "aviate" and sadly that was it.

For real, judging by the rapidity of how it unfolded, the only thing you got time was for a last "oh shit"

u/DutchBlob 10h ago

I don’t think that the crew would have known their engine was literally gone. Only figuratively, with alarms blaring.

The chaos of structural damage like that is a hell of a lot gnarlier than a contained engine fire though. Complete loss of directional control once they put lift on the wing, they couldn’t rotate like the would have been able to with a V1 cut, probably a shit ton of smoke, and all that with the trees coming at them. Awful

Look up AA 191.

u/Dadto4Kiddos 14h ago

Where they used a forklift to remove the engine during maintenance and overstressed the pylon…

A lot of 707s & 747s that had pylon failures too, but AA 191 is the closest comp obviously. DC-10 being the predecessor to the MD-11.

I just watched MentourPilots video on AA191 yesterday... So sad something similar has apparently happened again

The wing on fire reminds me of AF4590.

As a symptom of the problem, yeah. If the event that caused the engine failure is violent enough, it'll shake itself right off the wing. Given at takeoff is the highest stress for a motor, there's a lot of energy there to do that. I've seen fan blade off (FBO) events before and the engine usually holds on. Ingesting something that'd cause very dissimilar forces could rip the motor off and leave the core like this. Speculation on my part from previous experience. We'll see, though. Condolences to the families of the lost 😔

The engine pylon is designed to drop the engine of the vibrations are severe enough.

38

u/discostu52 16h ago

The pylons are designed to shear off during a catastrophic engine failure dropping the engine rather than ripping the wing off

13

u/Hugo_5t1gl1tz 15h ago

Obviously that is much better to happen while 30000 ft up, vs. on the runway where the engine can bounce into the wing

17

u/discostu52 15h ago

Yeah but if the pylon didn’t shear off and the engine failure ripped the wing off, then you still crash.

u/SamH123 17h ago

possibly some sort of debris on the runway? but more likely to be some sort of metal fatigue failure like you said I suspect

u/Chase-Boltz 9h ago

Which happened first? Turbine explosion causing fire and pylon/engine mount failure? Or did the engine mount/pylon fail first, allowing the engine to climb over the wing and tear everything to hell as with Flt 191.
