Rolls-Royce plc Turbofan Engines
This AD applies to all Rolls-Royce plc (RR) RB211-524G2-19, RB211-524G2-T-19, RB211-524G3-19, RB211-524G3-T-19, RB211-524H2-19, RB211-524H2-T-19, RB211-524H-36 and RB211-524H-T-36 engines.
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211-524G2-19, RB211-524G2-T-19, RB211-524G3-19, RB211-524G3-T-19, RB211-524H2-19, RB211-524H2-T-19, RB211-524H-36 and RB211-524H-T-36 engines. This AD requires removal of affected low- pressure compressor (LPC) shafts. This AD was prompted by unauthorized repairs to the affected LPC shafts that reduced their expected life. The FAA is issuing this AD to address the unsafe condition on these products.
Within 30 days from the effective date of this AD or before exceeding 10,500 flight cycles (FCs) since new, whichever occurs later, remove LPC shaft, part number (P/N) UL24833, with serial numbers (S/Ns) PATH3113; PATH3121; PAVN1765, PAVN1853, PAVN2152, PAVN2157, PAVN2259, PAVN2636, PAVN2991, or PAVN2992.
After the effective date of this AD, do not install an LPC shaft, P/N UL24833 and with S/Ns PATH3113; PATH3121; PAVN1765, PAVN1853, PAVN2152, PAVN2157, PAVN2259, PAVN2636, PAVN2991, or PAVN2992, with 10,500 FCs since new, or greater, on any engine.
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.
