What to do
Operators must remove existing forward galley slotted drain covers and replace them with solid blanking plates, and block the associated drain tubing following Airbus Canada Service Bulletin BD500-530009. These actions must be completed within 12 months from 18 September 2020 unless already done. Maintenance teams should refer to the approved service bulletin for detailed instructions.
Summary
Airworthiness Directive CF-2020-30R1 addresses water ingress issues in the forward avionics bay caused by forward galley drains on Airbus Canada Limited Partnership aircraft models BD-500-1A10 and BD-500-1A11. This directive applies to specific serial numbers of these models and aims to prevent water from causing electrical short circuits that could affect avionics functionality. The directive updates previous requirements to reflect production modifications.
What changed
CF-2020-30R1 revises the original AD CF-2020-30 by reducing the applicability to exclude aircraft that have already been modified equivalently in production. It maintains the requirement to install solid blanking plates and block associated drain tubing to prevent water ingress into the forward avionics bay.
Why it matters
This directive is critical for operators and maintenance teams to prevent water damage that can cause avionics failures and increase crew workload. Compliance ensures continued airworthiness and operational safety by mitigating risks of electrical short circuits in the forward avionics bay. It also helps maintain regulatory compliance under Canadian Aviation Regulations.
