FAA proposes AD for Airbus BO-209 rudder corrosion inspections

The FAA proposes a new airworthiness directive for all Airbus Defence and Space BO-209 and Bölkow Jr. models after corrosion damage was reported on the rudder drive. The AD would mandate repetitive inspections, corrective actions including replacement, and corrosion inhibitor application, and would prohibit installation of affected parts. This is a routine safety regulation with no immediate market impact.
