Airworthiness Directive · Amendment 39-22615 · Turbine engine compressor section
Rolls-Royce Deutschland Ltd & Co KG Engines
This AD applies to Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211-Trent 875-17, RB211-Trent 877-17, RB211-Trent 884-17, RB211-Trent 884B-17, RB211-Trent 892-17, RB211-Trent 892B-17, and RB211-Trent 895-17 engines.
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211-Trent 800 engines. This AD is prompted by reports of cracks on certain intermediate-pressure compressor (IPC) rotor shaft balance lands. This AD requires initial and repetitive on-wing or in-shop borescope inspections (BSIs) of certain IPC rotor shaft balance lands for cracks, dents, and nicks, and replacement of the IPC rotor shaft if necessary, and would prohibit the installation of a certain 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 (EASA) AD 2023-0040, dated February 16, 2023 (EASA AD 2023-0040).
(1) Where EASA AD 2023-0040 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 2023-0040.
(3) Where the service information referenced in EASA AD 2023-0040 specifies to use certain tooling, equivalent tooling may be used.
Although the service information referenced in EASA AD 2023-0040 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.
