What to do
Operators of affected BD-500-1A10 and BD-500-1A11 aircraft must inspect the Hi-Lite fasteners and FIREX lines within 24 months of August 8, 2023, or before reaching 17,000 total accumulated flight hours, whichever comes first. Any fasteners not meeting clearance requirements must be replaced or reoriented, and damaged FIREX lines must be repaired according to Airbus Canada Service Bulletin BD500-534006 Issue No. 001 or later approved revisions. Compliance must be documented and maintained as per Canadian Aviation Regulations.
Summary
Airworthiness Directive CF-2023-58 addresses fire protection concerns related to the fire extinguishing system (FIREX) on Airbus Canada Limited Partnership aircraft models BD-500-1A10 and BD-500-1A11. The directive focuses on inspecting and correcting line fouling caused by Hi-Lite fasteners in the center mid fuselage and keel beam areas. It mandates inspections and potential repairs to ensure the cargo compartment fire extinguishing system remains fully operational.
What changed
This new Airworthiness Directive introduces mandatory inspections of specific Hi-Lite fasteners and FIREX lines to verify minimum clearance and prevent line fouling. It requires replacement or reorientation of fasteners that do not meet clearance standards and repair of any damaged FIREX lines. The directive applies to certain serial numbers of the BD-500-1A10 and BD-500-1A11 aircraft models.
Why it matters
This directive is critical for maintaining the integrity and reliability of the cargo compartment fire extinguishing system, which is essential for flight safety. Operators and maintenance organizations must ensure compliance to prevent potential system failures that could leave the aircraft vulnerable to undetected fires. Adhering to this directive helps avoid dormant failures that could compromise emergency fire suppression capabilities.
