Why It Matters
This directive is critical for aviation professionals to ensure the continued airworthiness and safety of Airbus A350 aircraft powered by Trent XWB engines. Compliance prevents unsafe conditions caused by failure to adhere to mandatory life limits and inspection requirements. Maintenance organizations and operators must update their maintenance programs and procedures to align with the latest manufacturer-approved limitations, ensuring regulatory compliance and operational safety.
What To Do
Operators and maintenance organizations must replace engine components before exceeding life limits and perform mandatory inspections as specified in the updated Time Limits Manual starting from 06 April 2020. They must revise the approved Aircraft Maintenance Programme to include the new or more restrictive instructions within 12 months of the effective date.
