Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines
Superseded. A later AD replaced this one: AD 2021-17-12. Comply with the one in force.
This AD applies to all Rolls-Royce Deutschland Ltd. & Co KG (Type Certificate previously held by Rolls-Royce plc) Trent 1000-D2, Trent 1000-J2, and Trent 1000-K2 model turbofan engines with fuel pump, part number (P/N) G5030FPU01, installed.
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd. & Co KG (RRD) Trent 1000-D2, Trent 1000- J2, and Trent 1000-K2 model turbofan engines with fuel pump, part number G5030FPU01, installed. This AD requires removal and replacement of the fuel pump with a part eligible for installation. This AD was prompted by the manufacturer's investigation into an unexpected reduction in fuel pump performance in certain high life fuel pumps. The FAA is issuing this AD to address the unsafe condition on these products.
Remove fuel pump, P/N G5030FPU01, and replace it with a part eligible for installation within the compliance times specified in paragraph (g)(1) or (2) of this AD, whichever occurs later:
(1) Before exceeding 16,000 hours in service or 4,900 engines cycles in service since new, or since last overhaul; or
(2) Within 30 days after the effective date of this AD.
For the purpose of this AD, a “part eligible for installation” is a fuel pump that has not exceeded the compliance times specified in paragraph (g)(1) of this AD.
Note 1 to paragraph (h): Additional information on a sub-population of parts that are eligible for installation can be found in Appendix 1 of Rolls-Royce plc Alert Non-Modification Service Bulletin Trent 1000 73-AK581, dated May 12, 2020.
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.
