Time Limits / Maintenance Checks — Time Limits Manual / Maintenance Programme — Amendment
Summary
EASA Airworthiness Directive 2024-0062 is an amendment addressing Rolls-Royce Trent 1000 engine models Trent 1000-A, -AE, -C, -CE, -D, -E, -G, and -H. This directive updates the Time Limits Manual and Maintenance Programme requirements to ensure continued airworthiness of these engines. It mandates compliance with the latest maintenance tasks and life limits as specified in the revised Rolls-Royce Trent 1000 Time Limits Manual Revision 32.
What Changed
EASA Airworthiness Directive 2024-0062 supersedes the previous AD 2022-0259 and introduces updated maintenance instructions including new and/or more restrictive tasks, reduced thresholds, life limits, and intervals. It also requires operators to ensure that Direct Accumulation Counting (DAC) data files match the updated DAC tables in the maintenance documentation. The directive incorporates the latest revision of the Time Limits Manual published by Rolls-Royce.
Why It Matters
This directive is critical for aviation professionals because it mandates updated maintenance and replacement schedules to prevent unsafe conditions in Trent 1000 engines. Operators and maintenance organizations must comply to ensure regulatory conformity and maintain engine reliability and safety. Failure to comply could lead to unsafe engine operation and regulatory penalties.
What To Do
Operators must, from 20 March 2024, comply with the updated maintenance tasks and life limits specified in the Rolls-Royce Trent 1000 Time Limits Manual Revision 32. They must revise their approved Aircraft Maintenance Programme within 12 months of the effective date to incorporate these changes. Any discrepancies found during maintenance must be corrected according to Rolls-Royce approved procedures before the next flight or within specified compliance times.
