What to do
Operators of ACLP BD-500-1A10 and BD-500-1A11 aeroplanes must modify the mid avionics bay by applying sealant as detailed in Parts A and B of ACLP Service Bulletin BD500-530017 Issue 001. This modification must be completed within 2,450 flight hours from the effective date of 18 November 2026. The modification can be performed over multiple maintenance visits if necessary.
Summary
EASA Airworthiness Directive 2026-0213 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus Canada Limited Partnership BD-500-1A10 and BD-500-1A11 aeroplanes. The directive addresses a safety issue related to water ingress into the mid avionics bay, which can cause multiple system failures and increase flight crew workload. It mandates a modification to seal spaces in the fuselage to prevent fluid infiltration.
What changed
This new directive requires operators to apply sealant modifications as specified in ACLP Service Bulletin BD500-530017 Issue 001 to the mid avionics bay area of affected BD-500 aircraft. It reduces the compliance time compared to the previously issued Canadian AD CF-2026-16, which it also revokes concurrently. The directive introduces a mandatory modification to prevent water ingress that was not previously required by EASA.
Why it matters
This directive is critical for maintaining the continued airworthiness and safe operation of affected BD-500 aircraft by preventing water ingress that can lead to cascading failures of essential avionics systems. Operators and maintenance organizations must comply to avoid potential flight diversions and increased crew workload caused by system losses. Compliance ensures regulatory adherence and reduces operational risks associated with fluid infiltration in the mid avionics bay.
