Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines

Riepilogo

The FAA is adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Tay 611-8C model turbofan engines. This AD was prompted by reports of low-pressure compressor (LPC) rotor blade retention lug failure. This AD requires limiting the service life of the LPC rotor blades based on the number of dry-film lubricant (DFL) re-applications. The FAA is issuing this AD to address the unsafe condition on these products.
