Description

The FAA is superseding Airworthiness Directive (AD) 2023-26-04 for all Rolls-Royce Deutschland Ltd & Co KG Model Trent 1000 series engines. The previous AD required initial and repetitive in-shop visual inspections of certain air transfer tubes and air feed tubes for cracking, damage, or air leakage wear, with replacement if necessary. The new AD adds initial and repetitive on-wing visual inspections of these tubes and increases the inspection interval for the in-shop inspections of front bearing housing IP8 air feed tubes. This action addresses an unsafe condition that could lead to engine damage and reduced control of the airplane.
