The FAA's summary their words, unchanged

The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) Tay 611-8, Tay 620-15, Tay 650-15, and Tay 651-54 series turbofan engines, with certain low pressure (LP) compressor modules installed. This AD requires an ultrasonic inspection (UI) of LP compressor fan blades for cracks, within 30 days after the effective date of the AD on certain serial number (SN) Tay 650-15 engines. This AD also requires initial and repetitive UIs of LP compressor fan blades on all engines. This AD 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. This AD results from a report that a set of LP compressor fan blades failed before reaching the LP compressor fan blade full published life limit. We are issuing this AD to prevent LP compressor fan blades from failing due to blade root cracks, leading to uncontained engine failure and damageto the airplane.

The following P/N LP compressor fan blades are installed in these modules: Tay 611-8 LP Compressor Fan Blade P/Ns Tay 620-15 LP Compressor Fan Blade P/Ns Tay 650-15 LP Compressor Fan Blade P/Ns Tay 651-54 LP Compressor Fan Blade P/Ns JR30649 JR31702 JR31983 JR30649 JR31702 JR31983 JR33863 JR33864 JR31911 JR31912 JR35120 JR35121 JR33865 JR33866 JR31911 JR31912 JR35120 JR35121 Unsafe Condition (d) This AD results from a report that a set of LP compressor fan blades failed before reaching the LP compressor fan blade full published life limit. We are issuing this AD to prevent LP compressor fan blades from failing due to blade root cracks, leading to uncontained engine failure and damage to the airplane. Compliance (e) You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done. Ultrasonic Inspection (UI) of LP Compressor Fan Blades for Certain Tay 650-15 Engines That Have Not Yet Had UI of the LP Compressor Fan Blades (f) For Tay 650-15 engines, serial numbers 17201, 17202, 17226, 17253, 17341, 17356, 17428, 17450, 17457, 17458, 17497, 17530, 17622, 17643, 17655, 17678, 17709, 17751, 17755, 17805, and 17806 that have not yet had UI of the LP compressor fan blades: (1) Within 30 days after the effective date of this AD, perform UI of the LP compressor fan blades for cracks.
