Abstract
We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires repetitively inspecting the interior and the exterior of the main tubular spar of the rudder assembly for corrosion, taking necessary corrective action if corrosion is found, and applying corrosion protection. This AD retains the requirements of the previous AD and changes the compliance time for certain products listed above. This AD was prompted by our determination that the compliance time specified for Models G-164, G- 164A, and G-164B airplanes does not adequately address the unsafe condition. We are issuing this AD to detect and correct corrosion in the rudder main tubular spar, which could result in failure of the rudder main spar tube. This failure could lead to loss of directional control.
