"To detect cracks in the low-pressure turbine (LPT) casings, which could result in the release of uncontained high- energy debris in the event of a stage 1 blade failure."

Two ADs for other models - but with similar causes. Vent tube blockages.
AD 2010-06-14. 700s series has a problem similar to 800s series. (Boeing 777s) Could this same problem extend to 900s series on A-380s ?
"The Trent 800 has a similar type design standard to that of the Trent 700 and has also been found in service to be susceptible to carbon deposits in the oil vent tube. We are issuing this AD to prevent internal oil fires due to coking and carbon buildup in the HP/IP turbine bearing oil vent tube that could cause uncontained engine failure and damage to the airplane".

AD 2010-07-09. RB211-Trent 700 Series. This AD supersedes AD 2007-02-05. These engines are installed on, but not limited to, Airbus A330-243, -341, -342 and -343 series airplanes. "Background; This AD results from further analysis that the cleaning of the vent tubes required by AD 2007-02-05 could lead to loosened carbon fragments, causing a blockage downstream in the vent flow restrictor. We are issuing this AD to prevent internal oil fires due to coking and carbon buildup that could cause uncontained engine failure and damage to the airplane."

Another AD for 900s series but no mention of uncontained explosion.
2009-18-13; Title: Rolls-Royce plc. (RR) RB211 Trent 900 Series Turbofan Engines
"We are issuing this AD to prevent the release of a high-pressure (HP) turbine blade, which could result in an engine power loss or in- flight shut down of one or more engines, resulting in an inability to continue safe flight. Evidence from development testing and flight test Trent 900 engines has identified cracking on some HP Turbine Nozzle Guide Vane (NGV) Convex Surfaces."
