## Summary

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