Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines

Document 2026-11179 is a Final Rule published by the Department of Transportation in the Federal Register on June 4, 2026, with an effective date of July 9, 2026. The FAA is superseding Airworthiness Directive (AD) 2023-26-04 for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 1000-AE3, Trent 1000-CE3, Trent 1000-D3, Trent 1000-G3, Trent 1000-H3, Trent 1000-J3, Trent 1000-K3, Trent 1000-L3, Trent 1000-M3, Trent 1000-N3, Trent 1000-P3, Trent 1000-Q3, and Trent 1000-R3 engines. AD 2023-26-04 required initial and repetitive in-shop visual inspections of the intermediate-pressure stage 8 (IP8) and high-pressure stage 3 (HP3) air transfer tubes and front bearing housing IP8 air feed tubes for cracking, damage, or air leakage wear, and replacement, if necessary. Since the FAA issued AD 2023-26-04, the FAA has determined that a new set of initial and repetitive on-wing visual inspections of the IP8 and HP3 air transfer tubes for cracking, damage, or air leakage wear are necessary, and consequently the inspection interval for the repetitive in-shop visual inspections of front bearing housing IP8 air feed tubes may be increased. This AD requires initial and repetitive in-shop visual inspections of the IP8 and HP3 air transfer tubes and front bearing housing IP8 air feed tubes (with increased inspection interval) for cracking, damage, or air leakage wear, and replacement, if necessary. This AD also requires initial and repetitive on-wing visual inspections of the IP8 and HP3 air transfer tubes for cracking, damage, or air leakage wear, and replacement, if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
