Airworthiness Directive · Amendment 39-22538 · Turbine engine compressor section
Rolls-Royce Deutschland Ltd. & Co. KG Engines
This AD applies to Rolls-Royce Deutschland Ltd. & Co. KG Model RB211 Trent 768-60, 772-60, and 772B-60 engines.
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd. & Co. KG (RRD) Model RB211 Trent 768-60, 772-60, and 772B-60 engines. This AD was prompted by reports of cracks on affected intermediate-pressure compressor (IPC) rotor shaft balance lands. This AD requires repetitive on-wing or in-shop borescope inspections (BSIs) of the affected IPC rotor shaft balance land for cracks and replacement of any IPC rotor shaft if necessary and prohibits the installation of an affected IPC rotor shaft on any engine, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraphs (h) and (i) of this AD: Perform all required actions within the compliance times specified in, and in accordance with, European Union Aviation Safety Agency AD 2022-0055, dated March 23, 2022 (EASA AD 2022-0055).
(1) Where EASA AD 2022-0055 refers to its effective date, this AD requires using the effective date of this AD.
(2) This AD does not adopt the Remarks paragraph of EASA AD 2022-0055.
(3) Where the service information referenced in EASA AD 2022-0055 specifies to use certain tooling, equivalent tooling may be used.
Although the service information referenced in EASA AD 2022-0055 specifies to notify the manufacturer or supply pictures to the manufacturer of any cracks, dents, or nicks, this AD does not include that requirement.
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.
