A) Inspect those portions of the aileron control cables that move in the area of the fair-leads near B.L. 20 (aft of the rear spar) for frayed or broken cable strands.

B) 1. To perform the inspections required by Paragraph B) 2.(a), identify those portions of the aileron control cables that move around the pulleys and:

  (a) disconnect either end of each aileron cable to provide sufficient slack to conduct the inspections, or

  (b) remove the aileron cables per manufacturer's instructions to conduct the inspections.

2. Inspect those portions of the aileron cables that move around the pulleys as follows:

  (a) Rotate the cable so that the cable tends to untwist and simultaneously simulate the curvature of the cable over the pulley and check for fraying and broken outer and inner cable strands.

C) Prior to further flight replace aileron control cables showing fraying or broken strands that are discovered during any inspections required by this AD.

D) Upon accumulation of 500 hours' time in service and at 500 hour intervals thereafter, replace all aileron control cables.
