Since the rudder autopilot interface is similar, the same condition could exist. Loose bridle cable clamps, unless detected and corrected, could result in the swaged ball unseating from the recess in the servo drum and contacting the cable guard pin. This failure could lead to very limited control of the rudder and/or aileron with consequent loss of control.                                                                                                                                                     |\n\n![](image.001.png)  \nDavid Villiers  \nDelegate of the Civil Aviation Safety Authority\n\n17 July 2009","sortOrder":0},{"sectionNumber":"AD/CESSNA 208/26","sectionType":"part","heading":"AD/CESSNA 208/26","content":"## AD/CESSNA 208/26","sortOrder":1},{"sectionNumber":"Autopilot Roll and Yaw ServosBridle Cabl","sectionType":"part","heading":"Autopilot Roll and Yaw ServosBridle Cable Clamps","content":"## Autopilot Roll and Yaw Servos  \nBridle Cable Clamps","sortOrder":2},{"sectionNumber":"9/2009 DM","sectionType":"part","heading":"9/2009 DM","content":"## 9/2009 DM","sortOrder":3}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":3,"scope_assessment":{"changed":false,"description":"This is a standard single-issue Airworthiness Directive addressing a specific safety defect in specific aircraft.
