Airworthiness Directive 2003-22-03
one-timeAirworthiness Directives; Rolls-Royce plc Trent 768-60 and Trent 772-60 Turbofan Engines
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) RB211 Trent 768-60 and Trent 772-60 turbofan engines. This AD requires reworking the low pressure (LP) turbine nozzle vane case, the LP turbine bearing support exhaust case, and the support arm bracket assemblies. This AD is prompted by a report of an LP stage 4 blade failure at the blade shank, resulting in severe radial distortion of the rear flange of the LP turbine case and failure of a number of attaching bolts, resulting in enough flange separation to allow the release of high energy debris. We are issuing this AD to prevent possible uncontained LP turbine case failure and damage to the airplane.
Which aircraft AD 2003-22-03 applies to
Applies to RB211 Trent 768-60 engines with serial numbers before SN 41056, and RB211 Trent 772-60 engines with serial numbers before SN 41056. Installed on, but not limited to, Airbus A330 series airplanes.
Whether AD 2003-22-03 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
