@enginealliance has announced today to the concerned A380 operators that an engine inspection campaign will be launched soon.
Well if "triple melt" didn't get it, what happened to the manufacturers incoming sonic inspection? surely in this day and age we shouldn't be talking about a defect so small that still resulted in a catastrophic crack progression in so few cycles.
So which is it?.
