## Summary

We propose to adopt a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-710 series turbofan engines. This proposed AD was prompted by service experience that demonstrated premature wear of the splined coupling on the fuel pump. This proposed AD would require replacement of the affected fuel pump splined couplings. We are proposing this AD to prevent failure of the engine and loss of the airplane.
