in 1996 Michael Crichton published his great book Airframe in which he discusses that very issue, including counterfeit parts.

The extension to all MD-11 regardless of engine is probably because it is unclear as to the cause of the pylon detaching. They may think it is due to engine failure, but are being cautious until they are certain of this. I expect to see a more specific directive, but that could take a while.

Seems likely, given that it has happened before.
Poor old DC-10 MD-11 rep takes another big hit. Does the USAF still use the KC-10?

According to WIkipedia, not since September 2024.

GE have covered this before, looking at turbine discs with both original and "pattern" turbine blades and the significant differences between them.
