Summary
The Transport Canada Civil Aviation Safety Alert CASA 2025-13 addresses inspection requirements for the A220 aircraft models BD-500-1A10 and BD-500-1A11 equipped with PW1500G engines. It highlights potential engine issues caused by debris from the number 4 bearing compartment detected through Oil Debris Monitoring (ODM) indications. The alert aims to inform owners, operators, and maintainers about these risks and recommended corrective actions.
What changed
This new safety alert introduces mandatory inspections and corrective maintenance actions for the PW1500G engine oil system following ODM indications related to number 4 bearing debris. It specifically applies to engines transported between Mirabel, Canada, and Airbus's final assembly line in Mobile, Alabama. The alert references ACLP Operators Information Transmission A220-OIT-79-00-001 Revision B dated 26 June 2024 as the source of detailed procedures.
Why it matters
This alert is critical for aviation professionals because unscheduled engine removals and in-flight shutdowns have occurred due to bearing debris, posing safety and operational risks. Operators and maintenance teams must promptly identify and address these issues to prevent engine failures and ensure continued airworthiness. Compliance with this alert supports regulatory reporting requirements and helps maintain fleet reliability.
