Also, this is not the first incident and it it's not the first Airworthiness Directive against the PW-4077. https://duckduckgo.com/?q=PW-4077+%22airworthiness+

  While I understand the point you're trying to make, I'd just like to note that if you type any mature engine for any aircraft into a search engine, you're going to find more than one Airworthiness Directive for that engine

    No point really, just interesting that they've had an eye on various metallurgy inspections for a while. This is at least the third engine--with Trent and GE--so maybe those guys had their share of AD's. Also props to the 777 platform for being modular here and bulletproof in general. edit. It's obviously a tradeoff of accepting a certain number of (usually) contained survivable fan events vs being able to afford flying them.
