This amendment adopts a new airworthiness directive (AD), applicable to Lockheed Model L-1011-385 series airplanes, that requires modifications of various fluid drainage areas of the fuselage. This amendment is prompted by incidents involving corrosion and fatigue cracking in transport category airplanes that are approaching or have exceeded their economic design goal; these incidents have jeopardized the airworthiness of the affected airplanes. The actions specified by this AD are intended to prevent degradation of the structural capabilities of the affected airplanes due to problems associated with corrosion.
