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

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2020-05- 01, which applied 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 2020-05-01 required initial and repetitive borescope inspections (BSI) of the high-pressure turbine (HPT) blades. AD 2020-05-01 also required replacement of HPT blades with parts eligible for installation when the HPT blades fail inspection or reach the new life limit. Since the FAA issued AD 2020- 05-01, RRD published updated service material introducing improved HPT blades and a combustion rear inner casing bypass case assembly, adding an acceptable method for installation of HPT blades, expanding the inspection area for BSIs of the HPT blade, adding limits for axial cracks of the HPT blades, reducing certain BSI thresholds, and removing a certain HPT blade life-limit. This AD requires performing initial and repetitive BSIs of the HPT blades for axial cracks and, depending on the results of the BSIs, this AD requires either performing additional BSIs or replacing the HPT blades. This AD also adds an optional terminating action for the repetitive BSIs of the HPT blades. 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 2026-12-06 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2026-12-06 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.
