AD 97-23-08 62 FR 60772

This amendment adopts a new airworthiness directive (AD) that applies to all Avions Pierre Robin Model R3000 airplanes that are equipped with yaw damper Modification No. 013. This AD requires inspecting the bridle cable ends for correct installation in the grooved screw, inspecting for correct cable winding on the capstan and correct cable tension, and correcting any discrepancies found. This AD also requires installing lockwire to the tension adjustment screw. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. The actions specified in this AD are intended to prevent the rudder control from becoming jammed because of the yaw damper control cables slipping out of the groove on the tension adjustment screw, which could result in a reduction in the directional controllability of the airplane.
