Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Tay 620-15 Engines
We are adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Tay 620-15 turbofan engines. This AD was prompted by reports of low-pressure compressor (LPC) fan blade retention lug failures. This AD requires reviewing the engine maintenance records and replacing the LPC fan blade with a part eligible for installation if the dry-film lubricant (DFL) treatment limit is exceeded. We are issuing this AD to address the unsafe condition on these products.
