AD applies to - - T972 only?
I am really puzzled by the corrective actions in this situation. Rolls Royce must have some really solid evidence to support the application to the T972 only, and not to the T970. Will they come to rue this decision?
And if the distinction is genuine, should not Qantas elect to derate their fleet to T970 thrust as an interim measure, until they are confident of the final fix?
