Old PW4000 engines are failing at alarming rate. Not even specific to 777.
They’re being prudent.
This was from 2018 – Same type of PW4000 engine.
From 2020 Dec – Same deal. blades went missing.
this was literally yesterday.
By airline standards 3 failures in 3 years (That we know of) all in the same type of engine by the same manufacturer is an alarming rate of failure.
Its hard to say what caused this issue before the NTSB report is released so its bad to make any definitive conclusions before we get an actual answer
And that’s after 2 minutes of Google.
Someone more informed can jump in and give the juicy bits, but going off memory this all doesn’t shock me as the companies are far more cozy with the FAA and things have gotten lax.
There’s a scene in the book Airframe like this. The people who work at ‘Boeing’ are watching a news report about an engine blowing up, a woman being interviewed says “I’m never riding another ‘Boeing’ plane again,” and the employees are talking shit about her.
777’s are one of the safest plane in the sky still. Most hull losses were pilot error, shot down or burnt on the ground. The PW4077 is showing its age though. Maybe some fan/hub replacements are needed on the oldest planes. But that’s really expensive for PM.
Pilots did there jobs well here. Flew the plane, brushed up on procedures, and put it on the ground safely.
Also, though I see a lot of reports that it was an uncontained failure, I’m not so sure thats the case. The fan case was intact, it more likely shook the cowl right off with the violent vibrations of a lost blade. But I’m just speculating.
