I smell niggercrime! All of P&W's PW1000G engines produced since 2016 must be replaced/repaired. (The PW1000G belongs to the new generation of geared turbofans, in theory a gorgeous piece of engineering. "Geared" fans are some sort of holy grail of jet engines. They decouple the fan from the jet engine via a gearbox, to greatly improve efficiency.)
The core of engine disks are usually made of various high temperature steels, depending on where in the engine they sit. And they get powder coated to make them durable&heat resistant. Now, these coatings are flawed. Because, the powder used was defective.
Here's why I smell nigger: I know that in aircraft QM, these powders are actually mandatory checked through spectral analysis before they are used. The lab technician must have turned a blind eye so that defective metal powder would pass through. It's simply not possible they didn't notice.
To repair the affected engines, the whole engine needs to be taken apart, and reassembled, rechecked etc. Essentially, a new engine. Reportedly, per engine that process takes about 250 days.
