Boeing 787 Engine Problems
 

It seems that not only there is a problem with General Elelectric's GEnx engines but also the Rolls-Royce Trent 1000.
ANA are cancelling flights, 9 on Friday and could be at least 350 till the end of September.
Apparently the anti-corrosion coating on the medium pressure turbine blade is failing.
Aircraft are being taken out of service to have this fixed.

There is a story here from Nikkei Asian Review.

Throw in the Neo issues with engines from P&W and it's fun all round for suppliers.

Neo = No Engine Option
