Summary
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
several reports regarding an important corrosion on the bearings with propagation to the bracket-hinge of the rudder. This corrosion has been discovered after rudder removals. This condition, if left uncorrected, could result in the loss of the rudder control on the airplane.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
