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