Resumen
We are superseding airworthiness directive (AD) 2015-17-19 for all Rolls-Royce plc (RR) RB211 Trent 768-60, 772-60, and 772B-60 turbofan engines. AD 2015-17-19 required inspection of the fan case low-pressure (LP) fuel tubes and associated clips and the fuel oil heat exchanger (FOHE) mounts and associated hardware. This AD requires an engine modification, which terminates the repetitive inspections. This AD was prompted by fractures on the LP fuel return tube at mid-span locations that were found with resulting fuel leaks. We are issuing this AD to correct the unsafe condition on these products.
