What to do
Operators of Airbus Canada BD-500-1A10 and BD-500-1A11 aircraft within the specified serial number ranges must modify the VFG power-feeder harness routing according to the instructions in the referenced Service Bulletin before accumulating 12,000 total flight hours if not already done. Maintenance teams should verify if the modification was previously completed under earlier Service Bulletin issues to receive credit. Compliance must be documented and maintained as per Canadian Aviation Regulations.
Summary
Canadian Airworthiness Directive CF-2023-24 addresses a safety issue on Airbus Canada Limited Partnership BD-500-1A10 and BD-500-1A11 aircraft models. The directive mandates modification of the variable frequency generator (VFG) power-feeder harness routing to prevent chafing that could cause loss of electrical power or fire. This directive applies to specific serial numbers of these aircraft and is issued under Canadian Aviation Regulation 521.427.
What changed
This new Airworthiness Directive requires operators to perform a modification on the VFG power-feeder harness routing as specified in Airbus Canada Limited Partnership Service Bulletin BD500-534101, Issue 007 or later approved revisions. Previously, this modification was managed as a fleet campaign without an AD, but due to incomplete compliance, the AD now mandates the modification to ensure all affected aircraft are addressed.
Why it matters
This directive is critical for aviation professionals because it addresses a potential safety hazard that could lead to electrical power loss or fire, impacting aircraft safety and reliability. Operators and maintenance organizations must ensure compliance to avoid operational disruptions and regulatory penalties. Compliance also supports continued airworthiness and reduces risk of in-service failures related to the VFG power-feeder harness.
