Summary
This document revises an earlier proposed airworthiness directive (AD), applicable to certain Saab Model SAAB 2000 series airplanes, that would have required repetitive inspections for excessive wear of the aileron control cables, cable guides, and cable pulleys located at the rear wing spars; and corrective actions, if necessary. That proposal also would have required repetitive replacement of the control cables and cable guides with new or serviceable components. That proposal was prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. This new action revises the proposed rule by expanding the applicability of the proposed rule to include additional airplanes. In addition, this new action provides for optional terminating action for the repetitive inspections. The actions specified by this new proposed AD are intended to detect and correct excessive wear on the aileron control cables, cable guides, and cable pulleys located at the rear wing spars, which could result in broken aileron control cables and consequent reduced controllability of the airplane.
