Summary
EASA Airworthiness Directive 2021-0217R1 is an amendment concerning Rolls-Royce Deutschland Ltd & Co KG Trent XWB-75, Trent XWB-79, Trent XWB-79B, and Trent XWB-84 engines, commonly installed on Airbus A350 aircraft. This directive mandates compliance with updated airworthiness limitations and maintenance instructions specified in the Rolls-Royce Trent XWB Time Limits Manual. It ensures continued airworthiness by enforcing mandatory inspections and life-limited part replacements.
What Changed
This revision removes Trent XWB-97 engines from the applicability of the directive following their coverage under a separate AD. It retains and updates the requirements for mandatory inspections and life-limited part replacements based on the latest Rolls-Royce Time Limits Manual revisions. The directive also clarifies compliance methods and AMP revision timelines.
Why It Matters
This directive is critical for aviation professionals to maintain the safety and airworthiness of Airbus A350 aircraft powered by Trent XWB engines. Operators and maintenance organizations must adhere to the updated maintenance schedules and life limits to prevent unsafe conditions. Compliance ensures regulatory conformity and reduces the risk of in-service engine failures.
What To Do
Operators must replace components before exceeding life limits and perform mandatory inspections within specified intervals as per the Rolls-Royce Trent XWB Time Limits Manual. They must revise their approved Aircraft Maintenance Programme within 12 months after 7 October 2021 to incorporate these instructions. Any discrepancies found during inspections require corrective actions according to approved Rolls-Royce procedures before the next flight or within specified compliance times.
