"Rolls-Royce ... knew about the faults that the current airworthiness directive concerning these engines says are likely to have caused an intense oil fire in a structural cavity in the intermediate pressure turbine area of the engine."
"Rolls-Royce had designed and was introducing a fix for the oil leak issues for this into the engines at its own speed. "
"And the questions concerning the timeliness of the Rolls-Royce responses to a known problem, and its capacity and willingness to share them with the airlines concerned will not go away. "
So, bottom line. I'll ask if nobody else will. Is he saying that the engine blowup was due to a problem that Rolls-Royce knew about and failed to remedy in the in-service T900s?
