Abstract
We are superseding airworthiness directive (AD) 2013-05-18 for certain Rolls-Royce plc (RR) RB211 Trent 500 series turbofan engines. AD 2013-05-18 required initial and repetitive inspections of the low- pressure (LP) fuel tubes, fuel tube clips, and fuel/oil heat exchanger (FOHE) mounts for evidence of damage, wear, and fuel leakage. This AD reduces the repetitive inspection intervals. This AD was prompted by additional service experience. We are issuing this AD to correct the unsafe condition on these products.
