## Abstract

This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) T95-15-52 that was sent previously to all known U.S. owners and operators of certain Boeing Model 747-100 and -200 series airplanes by individual telegrams. This AD requires a revision of the Airplane Flight Manual (AFM) and Airplane Weight and Balance Supplement to restrict cargo loading to a certain level. This AD also provides for the removal of the restrictions following accomplishment of a modification of the longitudinal floor beams. This amendment is prompted by a determination that inadequate strength in the floor beams exists on certain airplanes that have been modified for cargo configurations. The actions specified by this AD are intended to prevent failure of the longitudinal floor beams, which may cause the keel beam to fail and result in rupture of the fuselage.
