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

What this AD requires

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.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Whether AD 2026-10-21 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2026-10-21 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
