Action
Final rule.
Summary
We are adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-725A1-12 turbofan engines. This AD requires removal of affected fuel metering units (FMUs) on RRD BR700-725A1-12 engines. This AD was prompted by reports of wear on the receptors of the double-ended unions in the FMU housing on BR700-725A1-12 engines causing fuel leakage. We are issuing this AD to prevent failure of the FMU, which could lead to damage to one or more engines and damage to the airplane.
