ATA 55

Horizontal pitch trim rod end adjustments are distinctly different even though the actuator itself is the same for both part numbers (543502-1 for the 1124 and 543502-501 for the 1123 and 1124A). Due to the critical nature of the adjustment, ordering and installing the correct unit cannot be over emphasized. The proper adjustment and configuration is preset and the parts marked accordingly on all Worthington Aviation stock actuators.
