Gain visual access to the rudder bar assembly and check for proper rudder control operation, as follows: a. Ensure that there are no hose clamps or zip ties (Ty-Raps) attached to the torque tubes of the rudder pedal and bar assembly. Verify the free and correct movement of the rudder pedal and bar assembly. b. Ensure that the routing of wiring, cables, and plumbing, and system components adjacent to the rudder controls, do not present a snagging hazard to, or interference with, the rudder controls. 2.
