Airworthiness Directive · Amendment 39-15539 · Rolls-Royce plc (RR) RB211 Trent 500 Series Turbofan Engines
Rolls-Royce plc (RR) RB211 Trent 500 Series Turbofan Engines
This AD applies to Rolls-Royce plc (RR) RB211 Trent 553-61, 553A2-61, 556-61, 556A2-61, 556B-61, 556B2-61, 560-61, and 560A2-61 turbofan engines with an intermediate pressure compressor (IPC) drum, part number (P/N) FK30102, installed. These engines are installed on, but not limited to, Airbus A340-500 and 600 series airplanes.
The FAA is superseding an existing airworthiness directive (AD) for RR RB211 Trent 553-61, 553A2-61, 556-61, 556A2-61, 556B-61, 556B2-61, 560-61, and 560A2-61 turbofan engines. That AD currently requires removing certain serial-numbered intermediate pressure compressor (IPC) drums, part number (P/N) FK30102. This AD requires removing those same IPC drums, and requires a new reduced life limit for all other IPC drums, P/N FK30102. This AD results from an RR engineering assessment that it is necessary to reduce the cyclic lives of the other drums with the same P/N. We are issuing this AD to prevent uncontained loss of IPC stage 1 blades, which could result in damage to the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
For engines with an IPC drum, P/N FK30102, that has an SN specified in Table 1 of this AD, remove the IPC within 2,910 cycles-since-new (CSN) or the next overhaul after the effective date of this AD, whichever occurs first.
| MW0134967 | MW0131219 | MW0156891 |
| MW0158192 | MW0164840 | MW0168864 |
| MW0168190 | MW0171399 | KHI00012 |
For engines with an IPC drum, P/N FK30102, that doesn't have an SN specified in Table 1 of this AD, remove the IPC drum within 5,830 CSN.
After the effective date of this AD, do not install the following:
(1) IPC drums, P/N FK30102, that have an SN specified in Table 1 of this AD, and have accumulated or exceeded 2,910 CSN.
(2) IPC drums, P/N FK30102, that don't have an SN specified in Table 1 of this AD, and have accumulated or exceeded 5,830 CSN.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
