Description
The part number A27088-18 refers to a “Link – Dummy, Trim Actuator, Aileron,” a specialized tool used in the maintenance of certain Boeing aircraft models, including the 747, 767, and 777 series. This tool facilitates the dispatch of an aircraft with an inoperative aileron trim system, as outlined in the dispatch deviation guides specific to each aircraft model.
The aileron trim system adjusts the neutral position of the ailerons to maintain level flight without continuous control input. If this system is inoperative, the A27088-18 dummy link allows maintenance personnel to mechanically set the ailerons in a neutral position, ensuring safe operation until repairs can be completed.
