What to do
Operators must inspect the affected rudder drive parts within two months of 30 December 2025 and then every five years thereafter, following the instructions in the Airbus Defence and Space service bulletins. If discrepancies are found, corrective actions must be completed before the next flight. After inspections and any corrective work, corrosion inhibitor must be applied before the next flight. Only serviceable parts may be installed from the effective date onward.
Summary
EASA Airworthiness Directive 2025-0284 is an airworthiness directive addressing the rudder control system drive inspection for Airbus Defence and Space GmbH Bölkow BO 208 and BO 209 aeroplanes. It mandates repetitive inspections and corrosion inhibitor applications on specific rudder drive parts identified by part numbers 208-31014 and 209-35264. The directive applies to all serial numbers of the BO 208 C Junior, BO 209 MONSUN, and BO 209 S models.
What changed
This new airworthiness directive introduces mandatory repetitive inspections and corrosion inhibitor applications for the rudder drive system on affected Bölkow BO 208 and BO 209 aeroplanes. It requires corrective actions if corrosion damage or discrepancies are found during inspections, including part replacement or cleaning. The directive also allows installation of affected parts only if they are serviceable and inspected as required.
Why it matters
This directive is critical for maintaining the structural integrity of the rudder drive system, preventing potential loss of rudder control due to corrosion damage. Operators and maintenance organizations must comply to ensure continued airworthiness and safe flight operations. Compliance helps avoid unexpected failures and supports regulatory adherence under EASA regulations.
