Not Surprized
You are absolutely right. It is not a surprize to RR. Maybe shouldn't be a surprize to us too if we follow RR a bit closer. Below is from "Asian Aviation" for talking 787 testing... Trent 1000 involved, offcourse: "... on 2 August, Rolls-Royce had suffered an uncontained failure involving a ‘Package A’-standard Trent 1000 destined to power 787 No 9. Unofficial reports suggest an oil fire had developed in the engine during high-power runs, softening the intermediate pressure (IP) shaft. A consequent shaft failure is understood to have permitted the IP turbine (IPT) to over-speed and disintegrate. Shed parts punctured the engine casing, damaging test equipment." Change Trent 1000 to Trent 900; change "test equipment" to "QANTAS A380", oh, don't forget the date too. Then you have an initial investegation report.
