Airworthiness Directive · Amendment 39-22019 · Turbine engine compressor section
Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce Plc) Turbofan Engines
This AD applies to Rolls-Royce Deutschland Ltd & Co KG (RRD) 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, Trent 1000-R3, Trent 7000-72, and Trent 7000-72C model turbofan engines installed as identified in European Union Aviation Safety Agency (EASA) AD 2019-0282R1, dated August 25, 2021 (EASA AD 2019-0282R1).
The FAA is superseding Airworthiness Directive (AD) 2020-20-07 for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) 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, Trent 1000-R3, Trent 7000-72, and Trent 7000-72C model turbofan engines. AD 2020-20-07 required initial and repetitive borescope inspections (BSIs) or visual inspections of the intermediate-pressure compressor (IPC) shaft assembly and, depending on the results of the inspection, replacement of the IPC shaft assembly. This AD was prompted by the manufacturer providing optional terminating actions for the required repetitive inspections and alternative inspection instructions. This AD continues to require initial and repetitive BSIs but allows modification of the engine in accordance with RRD service information as a terminating action to these inspections, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Perform all required actions within the compliance times specified in, and in accordance with, EASA AD 2019-0282R1.
(1) Where EASA AD 2019-0282R1 requires compliance from November 27, 2019, the effective date of EASA AD 2019-0282, this AD requires compliance from November 10, 2020, the effective date of FAA AD 2020-20-07.
(2) Where EASA AD 2019-0282R1 requires contacting Rolls-Royce for approved corrective actions if a crack is detected during any on-wing inspection and in-shop inspection, this AD requires removing the IPC shaft assembly and replacing it with a part eligible for installation before further flight.
(3) Where EASA AD 2019-0282R1 defines a serviceable part as an IPC shaft assembly which is not an affected part; or an affected part which is new (never previously installed on an engine); or an affected part that, before (re)installation, has passed (no crack detected) an inspection in accordance with the instructions of the NMSB, this AD also includes in that definition an IPC shaft assembly that, before (re)installation, has passed a visual inspection (no crack detected) of the exposed part using FAA-approved maintenance procedures.
(4) Where EASA AD 2019-0282R1 references on-wing inspections, this AD allows for a visual inspection of the IPC shaft assembly using FAA-approved maintenance procedures as a substitute for any on-wing borescope inspection if the affected part is exposed, provided that the compliance times specified in this AD are not exceeded.
(5) This AD does not mandate compliance with the “Remarks” section of EASA AD 2019-0282R1.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
