Unsafe Condition

The high-pressure turbine (HPT) blades may deteriorate, despite being subject to the inspections and life limits as specified in the current Rolls-Royce Time Limits Manual, T-Trent-10RRT, Chapters 05-10 and 05-20. This condition, if not detected and corrected, could lead to HPT blade failure, possibly resulting in engine in-flight shut-down (IFSD) and consequent reduced control of the aeroplane.

AI-generated summary from the source AD text. Verify against the official source before acting.

Required Actions

Initial and repetitive borescope inspections (BSI) of the HPT blades. Replacement of the HPT blades with parts eligible for installation when the HPT blades fail inspection or reach the new life limit.
