## Summary

This document revises an earlier proposed airworthiness directive (AD), applicable to all Dornier Model 328-100 series airplanes, that would have required repetitive inspections for chafing of various control cables, and replacement of any chafed cable with a serviceable cable. That proposal was prompted by chafing of various control cables found during inspections conducted at the manufacturer's facility and at overhaul facilities. This new action revises the proposed rule by expanding the areas to be inspected to detect damage and discrepancies, and providing for corrective action, if necessary; by adding a requirement for repetitive inspections of certain fairleads/swivel guides to detect damage and other discrepancies, and corrective action, if necessary; and by extending the compliance time for the initial inspections. The actions specified by this new proposed AD are intended to prevent failure of the pilot's control cables for the autopilot, elevator, rudder, aileron, and engine, which could result in reduced controllability of the airplane.
