What the agency says
The FAA is superseding Airworthiness Directive (AD) 2020-06-16 for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211 Trent 768-60, 772-60, and 772B-60 engines. AD 2020-06-16 required initial and repetitive ultrasonic inspections (UIs) of the affected low-pressure compressor (LPC) blades and, depending on the results of the UIs, replacement with a part eligible for installation. Since the FAA issued AD 2020-06-16, RRD issued updated service material providing improvements to the ultrasonic inspection procedures and updated initial inspection compliance times. This AD requires initial and repetitive UIs of the affected LPC blades for sub-surface anomalies and, depending on the results of the UIs, replacement with a part eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.
