Airworthiness Directives; Airbus Industrie Model A300, A300-600, and A310 Series Airplanes

Résumé

This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) T94-10-51 that was sent previously to all known U.S. owners and operators of certain Airbus Model A300, A300-600, and A310 series airplanes by individual telegrams. This AD requires a detailed visual inspection to detect cracks, delamination, or discoloration of the bus bar of certain aft fixed side cockpit windows; and deactivation of the window heating system and repetitive detailed visual inspections, or replacement of the window with a modified window, if necessary. This amendment is prompted by a report of fracture of a fixed cockpit window that led to electrical arcing in the bus bar area of the window heating system on a Model A300 series airplane. The actions specified by this AD are intended to prevent decompression of the fuselage during flight due to failure of a window.
