EASA AD 2023-0195
Time Limits / Maintenance Checks — Time Limits Manual / Maintenance Programme — Amendment
Summary
EASA Airworthiness Directive 2023-0195 is an amendment addressing Rolls-Royce Trent 1000 engine models including Trent 1000-AE3 through Trent 1000-R3. This directive updates the Time Limits Manual and Maintenance Programme to ensure continued airworthiness by mandating compliance with revised maintenance tasks and life limits. It applies to all serial numbers of the affected engines and supersedes a previous directive.
What Changed
EASA AD 2023-0195 supersedes AD 2023-0115 and incorporates updates from Rolls-Royce Trent 1000 Time Limits Manual Revision 29. Changes include the addition of a new low pressure compressor blade part number, a special tool update, and new overhaul limits for specific intermediate pressure compressor rotor blade part numbers. These revisions introduce new or more restrictive maintenance tasks and life limits.
Why It Matters
This directive is critical for operators and maintenance organizations to ensure compliance with mandatory airworthiness limitations, preventing unsafe conditions. It affects maintenance planning, requiring updates to Aircraft Maintenance Programmes and adherence to new inspection intervals and component life limits. Non-compliance could lead to grounding or unsafe operation of aircraft equipped with these engines.
What To Do
Operators must implement the updated maintenance tasks and component replacements as specified in the revised Time Limits Manual starting from the effective date. They must revise their approved Aircraft Maintenance Programme within 12 months of 23 November 2023 to incorporate the new limitations and thresholds. Any discrepancies found during maintenance must be corrected per Rolls-Royce approved instructions before further flight.
