Abstract
We are superseding an existing airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211 Trent 500 series turbofan engines. That AD currently requires a one-time inspection of the fuel tubes and fuel tube clips for evidence of damage, wear, and fuel leakage. This AD requires the same inspection, and adds additional repetitive inspections. This AD was prompted by additional RR engineering analysis. We are issuing this AD to prevent engine fuel leaks, which could result in engine damage and damage to the airplane.
