## Abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to all British Aerospace Model BAC 1-11 200 and 400 series airplanes, that currently requires a one-time inspection to determine the tension of the control cables of the thrust reversers, and to detect breakage, damage, wear, or signs of corrosion; and corrective actions, if necessary. This amendment requires that the inspections be repeated at certain intervals. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent failure of the control cables, which may lead to the inability of the thrust reverser to deploy and/or an uncommanded deployment of the thrust reverser while the airplane is in flight.
