EASA AD CF-2025-04
SUPERSEDED BY TCCA AD CF-2025-45
Summary
The Canadian Airworthiness Directive CF-2025-04 is a regulatory document addressing electrical wiring issues in the toilet A maintenance panel of Airbus Canada Limited Partnership BD-500-1A10 and BD-500-1A11 aircraft models. It mandates inspections and corrective actions to ensure proper securing and clearance of electrical harnesses near oxygen supply lines to prevent potential fire hazards.
What Changed
This directive introduces mandatory inspections of the electrical harness and sleeve in the toilet A circuit to detect wear or improper installation. It requires repairs of any damage found and installation of securing straps to maintain adequate clearance from oxygen supply lines, addressing a production issue with insufficient bending radii and loose harnesses.
Why It Matters
Compliance with CF-2025-04 is critical for operators and maintenance organizations to prevent electrical wear and potential ignition sources near oxygen lines, which could lead to uncontrolled fires. Ensuring proper harness installation enhances aircraft safety and regulatory compliance, reducing operational risks and maintenance costs.
What To Do
Operators must perform a detailed inspection of the electrical harness and sleeve within 12 months of the directive's effective date, following Airbus Canada Limited Partnership Service Bulletin BD500-254018 procedures. Any damage must be repaired and improperly secured harnesses must be fitted with securing straps before the next flight.
