What it does

The FAA proposes to supersede Airworthiness Directive (AD) 2023-26-04, which applies to 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 requires 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 proposed AD would continue to require 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 proposed AD would also require 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 proposing this AD to address the unsafe condition on these products.
