Louisville Plane Crash

One YouTube pilot spotted something on takeoff. Left engine had a catastrophic failure which threw shrapnel in all directions damaging the mounting points and it detached, and based on how low the engines hangs, the engine on the other side of the plane caught some of the debris and had a compressor stall (he spotted the telltale sign of the flame puffing of a compressor stall coming out of the right engine). Which means the tail engine was the only thing producing full thrust which is nowhere near enough to get that much weight into the air

 

Years ago the jet engines of certain aircraft types (Boeing 707s and early model 747s) actually had engines with fuze pins that were designed so the engines could break away from the aircraft especially in case of an engine fire so it wouldn’t compromise the rest of the aircraft. But after a few accidents where the breakaways resulted in the loss of the aircraft the fuze pins and engine pylons were redesigned to keep the engines on!

Okay then why catastrophic failure with debris flying everywhere?
I'm sure safety inspections are top-notch and these things shouldn't happen.

 

Well, I think what happened, is the fan inside disintegrated, and spinning at, what, 10,000 rpms, it appears in the video, it sheared the left wing off. The "debris" is probably cell phones and blenders and whatever else "Brown" carries, and is so important to take all these lives.

 

According to the dashcam video of it hitting the power lines before hitting the ground, the left wing was intact minus the engine. They can even zoom in to see that the slats on that wing were extended like they should be. The debris the guy mention was from the internal parts of the compressor blades when they get thrown out thru the side of the engine

 

Commerce makes the world go round the pilots got a paycheck from whatever they were hauling and that's fine. Toasters and cell phones paid the bills. We all do the same thing with the same risks to eat and keep the lights on. We dont think about it much but we all know anything could happen at anytime.

 

My money is either the compressor or even more likely the HPT or LPT(High Pressure Turbine or Low Pressure Turbine respectively) let go.
AA 767 High Pressure Turbine Failure

The aircraft involved was undergoing maintenance at LAX and doing an engine run-up when the turbine failed in spectacular fashion.
The aircraft involved was written off and scrapped due to its age.

 

it could literally be anything. A loose bolt. An incorrectly calibrated torque wrench. A slight defect in a fan blade. Just a defective part. A drone no one saw flew into it, a bird flew into it, someone shoot at it, a leak caused an unknown reaction with a newer material and made something weaker then it should be. A new part was tested on one type of plane of this class and this one was ever so slightly diffrent and caused a wobble. Someone didnt install the shroud right and it pinched enough under just such a condition to cause a failure. Bad fuel. Some little old lady throwing coins into it for luck.

All things that could and have happened before with stuff like this. Untill the report comes out, we just wont know.

Finding stress cracks so soon after the last pylon inspection... Lot of questions there. Missed? Developed that fast?
