Outside Canada, report occurrences according to local regulations.
Summary
Transport Canada Civil Aviation Safety Alert CASA 2024-01 is a safety alert addressing the incorrect installation of the outflow valve (OFV) coupling on Airbus Canada Limited Partnership aeroplanes models BD-500-1A10 and BD-500-1A11. The alert highlights that improper installation can damage the OFV coupling attachment points and potentially cause rapid cabin decompression. It provides guidance to owners, operators, and maintainers of these aircraft models to inspect and correct the installation as per Airbus service instructions.
What changed
This new safety alert identifies a specific issue with the OFV coupling assembly found during final assembly inspections, where the coupling was installed incorrectly contrary to drawing requirements. It introduces recommended inspection and corrective actions based on Airbus Canada Limited Partnership Service Bulletin BD500-213002 Issue 001 to prevent structural damage and ensure proper OFV coupling orientation.
Why it matters
The incorrect installation of the OFV coupling poses a serious safety risk by potentially causing rapid cabin decompression, which can endanger flight safety. Aviation professionals including operators, maintenance organizations, and compliance teams must address this issue promptly to maintain aircraft airworthiness and comply with regulatory reporting requirements. Timely detection and correction help avoid structural damage and ensure continued safe operation of affected aircraft.
