Airworthiness Directives; Airbus Defence and Space GmbH Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Defence and Space GmbH Model BO-209-150 FF, BO-209-150 FV, BO-209-150 RV, BO-209-160 FV, BO-209-160 RV, and B[ouml]lkow Jr. airplanes. This proposed AD was prompted by reports of corrosion damage on the rudder drive. This proposed AD would require repetitive inspections of the rudder drive, corrective actions including replacement if corrosion is detected and the application of a corrosion inhibitor. This proposed AD would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
