AD 2019-15-05 Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Turbofan Engines
Applicability*9
This AD applies to all Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent 1000-AE3, Trent 1000-CE3, Trent 1000-D3, Trent 1000-G3, Trent 1000-H3, Trent 1000-J3, Trent 1000-K3, Trent 1000-L3, Trent 1000-M3, Trent 1000-N3, Trent 1000-P3, Trent 1000-Q3 and Trent 1000-R3 engines.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Remove the HPT disk front cover plate, part number KH59279, from service prior to it reaching 1,250 engine cycles since first installation on an engine and replace with a part eligible for installation.
Unsafe condition
This AD was prompted by recent analysis of the material condition used in the manufacture of these parts that determined the high-pressure turbine (HPT) disk front cover plate may have a safe life below its declared safe cyclic life. The FAA is issuing this AD to prevent failure of the HPT disk front cover plate. The unsafe condition, if not addressed, could result in uncontained release of the HPT turbine disk front cover plate, damage to the engine, and damage to the airplane.
Affected ADs
None.
