Almost identical incident happened 3 years ago - the same type (B777-200), the same engine (PW4077), the same operator (United Airlines), the same side (right engine), the same failure (unconfined engine failure).

I would not be surprised if the whole fleet of this type/engine gets grounded for some time.
