A report in American Machinist says that ANA Holdings Inc., the world's largest operator of the 787 Dreamliner, confirmed it will replace or repair all Rolls-Royce Trent 1000 engines on its Boeing 787 Dreamliners in order to deal with an outbreak of cracks in the medium-pressure turbines caused by excessive vibration. The issue has caused All-Nippon Airways to cancel 18 flights in the past week, and reports indicate up to 300 more flights may have to be canceled in the coming weeks as the issue is addressed.
