Can some of the geniuses making these decisions explain to me HOW these incidents are supposed to indicate an endemic engine problem after over a quarter century of excellent service life of the PW4000?

And if throwing a fan blade out is such a huge issue why is it NOT an endemic problem for most of the ANA B787 fleet to be GROUNDED CONTINUOUSLY for about 7 YEARS due to the utterly inoperable trash RR motors?

And while we are at it, anyone has any memory of the Southwest B737-700 a few years ago that threw a compressor blade into the cabin causing the death of a passenger? Why wasn't the GE CFM56 engine grounded along with the tens of thousands of aircraft that use it?

Guess what folks: after these three motor makers all you got left is the Russian and the stolen copy Chinese engines!

Why don't you put yourself and your loved ones into aircraft powered by those if you are so worried about the safety of the PW4000? Because other than those options NO BIG JET MOVES!

Bruce, the PW4000-112 series engines are the highest thrust variant of that series of engines and are used only in the 777. That model engine has a history of fan blade failures. The FAA has increased the frequency of inspections of this series of engines however the most recent failure shows that even this higher frequency of inspections doesn't catch bad blades before they can fail. It is the only model of this engine with a history of multiple uncontained failures. Lower powered versions of the PW4000 series used in other aircraft do not have the same failure history the -112s have.
