EASA AD 2025-0119
Time Limits / Maintenance Checks — Time Limits Manual / Maintenance Programme — Amendment
Summary
EASA Airworthiness Directive 2025-0119 is an amendment concerning the Rolls-Royce Trent XWB series engines installed on Airbus A350 aircraft. It updates the Time Limits Manual and Maintenance Programme requirements for Trent XWB-75, Trent XWB-79, Trent XWB-79B, Trent XWB-84, and Trent XWB-97 engines to ensure continued airworthiness. The directive mandates compliance with the latest maintenance tasks and life limits as specified in the revised Rolls-Royce Trent XWB Time Limits Manual Revision 061.
What Changed
This amendment supersedes previous EASA ADs 2024-0065 and 2024-0116 by introducing new and more restrictive maintenance tasks and inspections, including updated engine mount pin and thrust strut inspections for Trent XWB-97 engines and new engine mount pin inspections for other Trent XWB models. It also updates part numbers, inspection intervals, and Direct Accumulation Counting data in the Time Limits Manual.
Why It Matters
The updated maintenance requirements are mandatory to prevent unsafe conditions caused by component failures or exceeded life limits. Operators, maintenance organizations, and compliance teams must adhere to these revised tasks to maintain aircraft airworthiness and regulatory compliance. Failure to comply could result in grounding of aircraft or unsafe operation.
What To Do
Affected operators must implement the updated maintenance tasks and life limits from the Rolls-Royce Trent XWB Time Limits Manual Revision 061 starting from 9 June 2025. They must revise their approved Aircraft Maintenance Programme within 12 months of the effective date to incorporate these changes. Any discrepancies found during inspections must be corrected within specified compliance times or before the next flight if no time is specified.
