We propose to adopt a new airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) Tay 620-15 turbofan engines. This AD limits service life of the low-pressure compressor (LPC) fan blades based on the number of dry-film lubricant (DFL) treatments. The AD was prompted by reports of LPC fan blade retention lug failures. We are proposing this AD to correct the unsafe condition on these products.
