## Summary

The FAA is withdrawing a notice of proposed rulemaking (NPRM). The NPRM proposed a new airworthiness directive (AD) that had applied to all Rolls-Royce Deutschland Ltd & Co KG (RRD) Tay 650-15 and Tay 651-54 turbofan engines. The proposed action would have required reducing the cyclic life limits for certain high-pressure turbine (HPT) disks. Accordingly, we withdraw the proposed rule.
