  ...however the exact type of engine Boeing is using for the 777 (PW4000-112 - https://en.wikipedia.org/wiki/Pratt_%26_Whitney_PW4000#PW4000-112 https://en.wikipedia.org/wiki/Pratt_%26_Whitney_PW4000#PW400...) is not used by any other airliner. I'm no expert, but as the most powerful -112 version has almost twice the thrust of the -94 version, I wouldn't automatically conclude that problems with one type mean that there are also problems with the other types. OTOH, if they take a closer look at the 777 engines and find a lot with problems that went undetected until now, I assume the other PW4000 engines will get a closer inspection as well...

    The core is the same. The different model numbers typically represent other configurations of the stages or pump throughput, type of FADEC, and all of these things.

    Its noted that a 747 had a very similar issue the same day as this 777 with the same series of engine. Since the issue is most likely with fracture detection during maintenance inspection and P&W introduced new procedures for that a few years back, its likely the issue is with the tech being used or the procedures. Which would mean any P&W engines using the same technologies and procedures to detect fan and turbine blade cracks would be affected.
