This AD was prompted by a report that the aileron trim cables can be connected incorrectly on a correctly installed aileron trim chain. We are issuing this AD to prevent incorrect connection of the aileron trim cables, which could result in failure of the aileron trim system and consequent reduced controllability of the airplane.
