## Summary

We propose to adopt a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) model Tay 611-8C turbofan engines. This proposed AD was prompted by reports of low- pressure compressor (LPC) rotor blade retention lug failures. This proposed AD would limit the service life of the LPC rotor blades based on the number of dry-film lubricant (DFL) re-applications. We are proposing this AD to address the unsafe condition on these products.
