## Summary

We propose to supersede airworthiness directive (AD) 2007-03- 02 for all Rolls-Royce Deutschland (RRD) Tay 620-15, Tay 650-15, and Tay 651-54 turbofan engines. AD 2007-03-02 requires an ultrasonic inspection (UI) of low-pressure (LP) compressor fan blades for cracks on certain serial number (S/N) Tay 650-15 engines. AD 2007-03-02 also requires, for all Tay 611-8, 620-15, Tay 650-15, and Tay 651-54 engines, initial and repetitive UIs of LP compressor fan blades. AD 2007-03-02 also requires, for Tay 650-15 and Tay 651-54 engines, UIs of LP compressor fan blades whenever the blade set is removed from one engine and installed on a different engine. Since we issued AD 2007-03- 02, we received a report of an additional engine failure due to multiple fan blade separation. This proposed AD would require additional inspections for the affected engines and removal of the Tay 611-8 engine from the applicability of this AD. We are proposing this AD to prevent failure of the LP compressorfan blade, engine failure, and damage to the airplane.
