Airworthiness Directive · Amendment 39-23273 · Engine bleed air system
Rolls-Royce Deutschland Ltd & Co KG Engines
This AD applies to all Rolls-Royce Deutschland Ltd & Co KG Model Trent 7000-72 and Trent 7000-72C engines.
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 7000-72 and Trent 7000-72C engines. This AD was prompted by the manufacturer's determination that certain intervals for visual inspection of the intermediate pressure 8 (IP8) and high pressure 3 (HP3) air tubes need to be reduced for certain engines, and instructions for visual inspection of the IP8 and HP3 air tubes were not available for certain other engines. This AD requires initial and repetitive visual inspections of the IP8 and HP3 air 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.
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 2023-0186, dated October 27, 2023 (EASA AD 2023-0186).
(1) Where EASA AD 2023-0186 requires compliance from its effective date, this AD requires using the effective date of this AD.
(2) Where paragraph (6) of EASA AD 2023-0186 states “any damage is detected”, this AD requires replacing that text with “any cracking, damage, or sign of air leakage is detected”.
(3) This AD does not adopt the “Remarks” paragraph of EASA AD 2023-0186.
Although the service material referenced in EASA AD 2023-0186 specifies to submit certain information to the manufacturer, 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.
