There have been two reported cases of the Austria Alpin pulley (Model No. FL12A) failing. The cause is an improperly set axle. It affects a small percentage of one batch of Austria Alpin pulleys. Please inspect your brake pulleys and check to see that the axle is secure and has been properly set in the pulley frame. If you notice any irregularities please report it immediately to your OZONE dealer and do not fly your wing. If the pulley axle were to fail in flight the result is the brake line detaching from the rear riser.
