What the agency says
The FAA proposes to supersede Airworthiness Directive (AD) 2020-06-16, which applies to certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211 Trent 768-60, 772-60, and 772B-60 engines. AD 2020-06-16 requires 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 proposed AD would continue to require 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 proposing this AD to address the unsafe condition on these products.
