What to do
Operators of affected Airbus Canada BD-500-1A10 and BD-500-1A11 aircraft must inspect the Motive Flow flexible fuel line assemblies within four months from March 25, 2021. If twisted or damaged fuel lines or shrouds are found, they must be replaced following the instructions in Airbus Canada Service Bulletin BD500-282011, Issue 001, or later approved revisions. Compliance with this directive is mandatory before conducting take-off operations.
Summary
Canadian Airworthiness Directive CF-2021-09 addresses a potential safety issue in Airbus Canada Limited Partnership BD-500-1A10 and BD-500-1A11 aircraft. It mandates inspection and corrective actions for twisted or damaged Motive Flow flexible fuel line assemblies in the pylon to wing area to prevent fuel leaks and fire risks. This directive applies to specific serial numbers of these aircraft models.
What changed
This new Airworthiness Directive introduces a requirement to inspect and, if necessary, replace the left and right Motive Flow flexible fuel line assemblies due to a newly introduced configuration that may cause twisting and abrasion. It specifies compliance with Airbus Canada Service Bulletin BD500-282011, Issue 001, or later approved revisions. The directive establishes a clear inspection and corrective action process to mitigate the identified risk.
Why it matters
This directive is critical for aviation professionals to prevent fuel leaks and potential fires caused by abrasion of twisted fuel lines near electrical harness connectors. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. Failure to comply could result in increased risk of in-flight fire hazards and regulatory non-compliance.
