A proposal is not in force. If adopted, it becomes an AD, usually with changes. Only the Federal Register edition is official.

Summary

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.

The resulting AD
