Adjust the Aileron and Aileron Trim Control System
NOTE: If you adjust the aileron trim control system without hydraulic
____ power, the drag will permit the aileron system (without power) to stay out of the center. This will push the cam follower of the trim and centering mechanism out of the cam detent. When you apply hydraulic power, the control wheels and the ailerons will quickly move to the new adjusted position.
