Given enough airplanes and time engines fail with one you are going down.
Maybe this AD is related to this incident?

Yes, however turbine bits flying out the exhaust is still considered contained.
They did not penetrate the outer engine casing, just went out the normal exit path.
@Arne, sorry, the video was too long for me, was there an information that the debris were contained inside the engine and exhaust?

Is my understanding correct that in an uncontained engine failure you have debris coming out of the engine, whereas in a contained failure the debris keeps inside? That is what skybrary teaches.skybrary for uncontained engine failure
My undersanding as well.

If it was contained engine failure, then, well, IT happens, so what.
If it was an UNcontained engine failure
Is my understanding correct that in an uncontained engine failure you have debris coming out of the engine, whereas in a contained failure the debris keeps inside? That is what skybrary teaches.

Well, the proof is in the pudding.
It looks like the whole compressor stage literally exploded. This is perhaps a common failure mode of these engines (when they eventually do fail), I don’t know, but it for sure must have made a load bang

In the video the former turbine is called PT and the latter CT .
Did he tell in one point in the video that missing blade is probably from PT?

Simply doing a lot of invasive work to be “safe” often results in the opposite. Lets cut that 80 year old person open and look inside, maybe we find something wrong. Hey wait the person died because of an unfortunate infection sustained during surgery…
During WWII, the RAF dramatically improved dispatch rate by increasing inspection intervals…
For better understanding, this is a dual-shaft engine with a “power turbine”, connected to the gearbox and driving the prop, and a “compressor turbine”, driving the..er, compressor. In the video the former turbine is called PT and the latter CT .
