EASA is expected to issue an AD on 787's powered by Rolls Royce Trent 1000 TEN after detecting higher wear on turbine blades. The AD comes after Singapore Airlines confirmed 2 787-10's being grounded due to higher wear.
The latest version of the Trent engine has been dogged by problems since entering service at the end of 2017. According to Rolls-Royce, by late February 35 787s had been grounded globally due to engine blades corroding or cracking prematurely.
“This blade deterioration is a known issue but it is occurring faster than we expected on some engines,” Chris Cholerton, Rolls-Royce President for Civil Aerospace, said on Wednesday.
