EASA AD 2022-0247
SUPERSEDED BY EASA AD 2023-0115
Summary
EASA Airworthiness Directive 2022-0247 is issued for Rolls-Royce Deutschland Ltd & Co KG Trent 1000 series engines, including models AE3, CE3, D3, G3, H3, J3, K3, L3, M3, N3, P3, Q3, and R3. This directive mandates compliance with updated airworthiness limitations and maintenance tasks as specified in the Rolls-Royce Trent 1000 Time Limits Manual Revision 23 dated 01 July 2022. It applies to all serial numbers of the affected engine models to ensure continued airworthiness.
What Changed
EASA AD 2022-0247 supersedes the previous AD 2020-0243 and incorporates new and more restrictive maintenance tasks, life limits, and inspection intervals introduced in the latest revisions of the Rolls-Royce Trent 1000 Time Limits Manual. Changes include updates to the Direct Accumulation Counting software, new inspection requirements for compressor shaft assemblies and high-pressure nozzle guide vane flap seals, and revised overhaul limits for certain components. The directive also mandates updating the Aircraft Maintenance Programme to reflect these changes.
Why It Matters
This directive is critical for aviation professionals as it ensures the safe operation and continued airworthiness of aircraft powered by Trent 1000 engines. Operators and maintenance organizations must adhere to the updated maintenance tasks and life limits to prevent unsafe conditions that could arise from component failures. Compliance helps avoid unplanned downtime, enhances safety, and meets regulatory requirements under EU aviation regulations.
What To Do
Operators must replace components before exceeding their life limits and perform all maintenance tasks within specified thresholds and intervals as detailed in the updated Time Limits Manual. Any discrepancies found during inspections must be corrected promptly following approved Rolls-Royce maintenance documentation. Additionally, the approved Aircraft Maintenance Programme must be revised within 12 months of the effective date to incorporate the new limitations and tasks.
