## Abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to all Lockheed Model L-1011 series airplanes, that currently requires the implementation of a corrosion prevention and control program either by accomplishing specific tasks or by revising the maintenance inspection program to include such a program. This action requires accomplishment of new specific tasks and visual inspections for corrosion of certain structural areas and repair if necessary, or revision of the maintenance inspection program. This amendment relates to the recommendations of the Airworthiness Assurance Task Force assigned to review Model L-1011 series airplanes, which indicate that, to ensure long-term continued operational safety, various structural inspections should be accomplished. The actions specified by this AD are intended to prevent structural failure of the airplane due to corrosion.
