## Summary

We propose to adopt a new airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co. KG (RRD) Tay 620-15, 650-15, and 651- 54 turbofan engines. This proposed AD was prompted by the discovery that the low-pressure compressor (LPC) fan blades leading edges erode in service and create an unacceptable blade flutter margin. This proposed AD would require replacement of LPC fan blades. We are proposing this AD to prevent LPC fan blade failure, damage to the engine, and damage to the airplane.
