Airworthiness Directive · Amendment 39-21648 · Engine turbine/turboprop
Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines
Superseded. A later AD replaced this one: AD 2022-13-17. Comply with the one in force.
This AD applies to Rolls-Royce Deutschland Ltd & Co KG (RRD) (Type Certificate previously held by Rolls-Royce plc) Trent XWB-75, Trent XWB-79, Trent XWB-79B, Trent XWB-84, and Trent XWB-97 model turbofan engines.
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent XWB-75, Trent XWB-79, Trent XWB-79B, Trent XWB-84, and Trent XWB-97 model turbofan engines. This AD was prompted by the manufacturer revising the time limits manual (TLM) to incorporate repairs to the low-pressure compressor (LPC) blades and introduce a new fan blade inspection. This AD requires revisions to the airworthiness limitations section (ALS) of the Rolls- Royce (RR) Trent XWB TLM and the operator's existing approved aircraft maintenance program (AMP). The FAA is issuing this AD to address the unsafe condition on these products.
Within 120 days after the effective date of this AD, revise the Rolls-Royce (RR) Trent XWB TLM, as applicable to each engine model, and the operator's existing approved aircraft maintenance program (AMP) by incorporating the following:
(1) For Trent XWB-75, Trent XWB-79, Trent XWB-79B, and Trent XWB-84 model turbofan engines, add Figure 1 to paragraph (g)(1) of this AD to the airworthiness limitations section (ALS) of RR Trent XWB TLM TRENTXWB-K0680-TIME0-01 and to the operator's existing approved AMP.
(2) For Trent XWB-97 model turbofan engines, add Figure 2 to paragraph (g)(2) of this AD to the ALS of RR Trent XWB TLM TRENTXWB-K0680-TIME0-01 and to the operator's existing approved AMP.
Note 1 to paragraph (g): Figure 1 to paragraph (g)(1) and Figure 2 to paragraph (g)(2) contain language from the original equipment manufacturer's TLM. Operators may incorporate the language referenced in Figure 1 to paragraph (g)(1) or Figure 2 to paragraph (g)(2) directly into their AMP instead of adding the respective figures into their AMP.
For the purpose of this AD, the operator's existing approved AMP is defined as the basis for which the operator or the owner ensures the continuing airworthiness of each operated airplane.
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.
